Functional Description 4.1 General The Stream810 module contains the core functions of a network audio streaming client featuring a dual core ARM Cortex microprocessor and a variety of data and control interfaces for flexible and economical use. Stream810 also contains the digital signal processing and networking functions required for many kinds of next generation network enabled products. The module can be the core of a complete, stand-alone network player or can serve as an add-in module providing network and USB playback capability for a more sophisticated audio product. A high quality clock is provided to support high performance A/D and D/A converters. Advanced clock synchronization features allow support of multi-room audio applications. When used in stand-alone mode, the audio output of Stream810 can be synchronized to an external IS Master Clock for ultimate audio performance (lowest jitter). Dual band WLAN 802.11a/b/g/n/ac and an Ethernet interface are provided for network connection. Two antennas are supported in 2T2R configuration; one of these is shared between WLAN and Bluetooth. Up to two USB OTG interfaces are supported. Bluetooth 4.2 is supported with internal WLAN coexistence interface. However, WLAN throughput may be reduced while Bluetooth A2DP audio is received. All functions are incorporated on a small footprint 47x51mm low-profile PCB board featuring dual 1.27mm male headers providing both mechanical and electrical connection to base board. Only few external components are required to build up a complete product, however Stream810 also fits perfectly into complex product architectures. Typical applications include:

Consumer Electronics o Connected Speakers o Mainstream CE products such as connected AV receivers o Premium CE products Building Technology o Residential Audio o Home Automation Institutional Audio/Video o Audio distribution in Hotels, Supermarkets, Airports Professional Audio Gateways between internet and proprietary interfaces 4.2 Default Software Configuration and Security The Stream810 supports secure boot and Trustzone. The boot sequence is configured to NAND flash boot regardless of state of pins on the external interfaces. Secure boot prevents that the module is booted with a non-authenticated bootloader. Trustzone is a secure sub-system in which calculations involving secret keys can be executed. StreamUnlimited Engineering GmbH Gutheil-Schoder-G. 10, 1100 Vienna, Austria Gutheil-Schoder-G. 10, 1100 Vienna, Austria T +43-1-667 2002, F +43-1-667 2002 4401 Stream810_HW_Specification_V_2_0_20180116.docx January 16, 2018 Updating Stream810 to customized SW, enabling security StreamUnlimited provides modules with a generic software (bootloader/linux image for upgrade/recovery) USB thumbdrive or network (tftp) can be used to program customized software image. For large volume production, a special programming jig is recommended, StreamUnlimited can provide reference schematics and layout. Although the update will start and complete autonomously, a PC or microcontroller should be used to monitor UART output of the module to notify operator when update has completed The customized software image has to be signed by module customer (referred to as OEM in this section). Signing happens offline, once per software release. This protects the software image against modification by third party (hacker), it is a requirement for GoogleCast enabled products. This Key will be referred to as OEM private Key StreamUnlimited provides tools and instructions for creation of key and signing of images. Only module customer/OEM knows the key, StreamUnlimited does not. If the key would be made publicly available, hackers could modify the software image and sign it again after the modification such that the module accepts booting it Modules delivered by StreamUnlimited accept any signed or unsigned software. After programming custom software which is signed using OEM private key, modules must be locked via UART to accept only images with the correct OEM key. No one except OEM (also not StreamUnlimited) will be able to run their own SW on such locked modules. Thus modules must only be locked AFTER product-level testing. To use GoogleCast and Google Voice Assistant, authentication with Google servers is required. Every module using these services must contain a secret key. It is usually unique for a product model but not unique for each sample, it is referred to as the "Google model key"

For security reasons, this "model key" is not part of the software image but needs to be inserted on the production line via UART The "model key" must be inserted AFTER module is locked For security reasons, locked modules do not provide access to linux debug shell via UART. They only allow insertion of "model key" via UART using a special protocol The "Google model key" is also created by OEM using tools provided by StreamUnlimited. It is only known to OEM, if it is made publicly available and used by hackers Google may revoke access to their services for all products based on this key StreamUnlimited will ensure that the key is registered at Google. OEM creates a public key using tools provided by SUE and transfers this to StreamUnlimited. StreamUnlimited will return a "certificate" based on this key. OEM must patch the customized SW image using this certificate During development, special keys and certificates can be created which have shorter validity than production keys SUMMARY:

OEM must create OEM key and Google model key, add Google certificate and sign image OEM production must lock modules after testing and insert Google key Both Google model key and OEM key are to be treated highly confidential, if they leak to the public products may stop to function in the field Backups of Google model key and OEM key need to be kept, if the keys are lost, field-

upgrades of products will not be possible anymore. SUE cannot retrieve the keys StreamUnlimited Engineering GmbH Gutheil-Schoder-G. 10, 1100 Vienna, Austria T +43-1-667 2002, F +43-1-667 2002 4401 Stream810_HW_Specification_V_2_0_20180116.docx January 16, 2018 4.3 Interfaces Stream810B / Basic Interface Single +5V power supply 100MBit Ethernet (on board PHY) Dual-band 802.11a/b/g/n/ac, 2 U.FL connectors to external antennas Bluetooth 4.2 Up to 5 GPIOs (typically one used as mute output) UART1 or 2 additional GPIOs. This UART is normally used for debug purposes. If UART1 pins are used for other function, debugging is possible via UART6 which is available on testpoints (not connected to interface header). High speed USB2.0 OTG port 10 bit ADC input (typically used for board revision detection) Audio interfaces:

o o IS out, up to two data lines IS in 1x IC (Master or Slave) Stream810B4.4W Interface To address the need for basic Voice Assistant products which only feature wireless network connection, a special interface option was introduced which replaces Ethernet lines with one additional I2S digital audio input for digital microphones. Separate clock lines are provided to be able to interface directly to digital (I2S-) microphones running at 16kHz. A third input is provided as echo-cancellation back-channel from external audio DSP. This back-channel line runs synchronously to the audio outputs. Stream810X / Extended Interface Interface options:

Three digital audio ports o Separate clock lines for input and output o Up to 3 I2S data input and output lines (up to 6 channels) One port can be run at different sampling frequency or even different format (TDM) than other two ports Two USB2.0 OTG interfaces 16 bit (RGB 565) LCD interface plus PWM output for external Backlight converter LCD pins can be used as GPIOs Two UARTs Three IC interfaces SPI interface with single chip select (Stream810 is master, to control more SPI peripherals, use GPIO in combination with hardware chip select) Three analog inputs (10 bit) I2C and I2S port pins can be used as GPIOs if primary function not required StreamUnlimited Engineering GmbH Gutheil-Schoder-G. 10, 1100 Vienna, Austria T +43-1-667 2002, F +43-1-667 2002 4401 Stream810_HW_Specification_V_2_0_20180116.docx January 16, 2018 Stream810H / Extended+ Interface Additional interface options:

All other pull-up resistors (including those for I2C) must be placed on application level. Supply pin 3V3_OUT is provided for that purpose. This supply output can be switched off to save power in a standby mode if Ethernet is not present on the product or not required to remain connected in a standby mode. Maximum external load on 3V3_OUT is 100mA. On-board Ethernet port Stream810 offers an integrated Fast Ethernet PHY. Magnetics and ESD protection has to be provided externally from the Stream810 module. No LED outputs are provided. Network connection status is available on host interface (HostLink). For host-less applications, LED for connection status (including WLAN) can be driven by GPIO or PWM. Route the Ethernet lines as differential pairs with differential impedance of 100 Ohms. Note that the Center Tap of Ethernet magnetic should be connected to 3V3_OUT. Figure 6 Ethernet Example Schematics MAC addresses: Stream810 is delivered with unique MAC address.

The ID pin should be grounded on application level to select host mode. Although the hardware is able to serve as USB device, only host mode is supported in software. Voltages on USB1_VBUS and USB2_VBUS must be within 4.5V and 5.2V when USB is active. These voltages must follow control signals USB1_DRVVBUS and USB2_DRVVBUS (high-

active, 3V3 logic). When VBUS voltage of active port drops below 4.5V then an overload/short circuit condition is assumed and the port will be disabled by application software. The VBUS level will subsequently be checked every second and the port will be enabled again as soon as the voltage recovers. If a port is not used/connected on product level it must be disabled in devicetree configuration which describes the hardware. Note that the overload/short circuit checking algorithm is only enabled after booting completed, it is not present in the bootloader.

An external display backlight converter is required. The converter can be controlled via LCD_DIM_PWM for on/off and brightness level control. See below for schematics example. Figure 9 LCD Backlight dimming example Please note that Stream810 does not feature an OpenGL graphics accelerator to offload the CPU. Any rendering is done via CPU. Optionally the integrated "pixel processor" could be used which offers acceleration of basic GUI related operations such as scaling and alpha-blending. Note that higher display resolution will increase both EMI and CPU load. A resolution of 800x480 or lower is recommended.

The Master clock is by default provided from an on-board PLL or provided from an external clock generator. The on board PLL allows fine-adjustment to synchronize multiple clients playing the same content synchronously. For Stream810B (Basic Interface) the input and output must run synchronously. This is also the preferred operating mode for Stream810X and Stream810H, however dedicated input and output clock lines are provided on the extended interface. These can also be used for other purposes such as additional GPIOs or I2S data lines. Default clock ratios/frequency I2S_BCLK / I2S_WCLK: 64 I2S_MCLK: 22.5792MHz or 24.576MHz If SPDIF output is required use of an external SPDIF transmitter (such as AK4104) driven from I2S output is recommended. Contact StreamUnlimited should you wish to use an external audio clock. Adding the required host interface and appropriate clock control algorithms may require customization work. A tune-

able external clock is required.

The WLAN interface is IEEE 802.11ac compliant, with 2x2 MIMO spatial stream multiplexing with data rates up to MSC9. Antenna ports are 50 Ohms using IPEX (U.FL.) type connectors, no external matching components are required. CON107 is only for WLAN, CON108 is shared between WLAN and Bluetooth. CON108 is located near to corner of module pcb. Module Reset Stream810 features a reset input. To avoid corruption of the NAND flash content it is recommended to pull the module reset line low immediately when the external supply voltage decreases below the specified minimum voltage. As an example, if the product is supplied by 12V AC/DC adapter and a 5V DC/DC converter is used to supply Stream810, the reset line can be activated when external supply drops below 10V in which case the 5V DC/DC converter will still keep the supply of Stream810 stable long enough to allow the internal NAND flash controller to finish the write access before NAND flash supply drops and thus flash integrity is maintained. To reset the module via an external controller an open drain output must be used. Figure 21 Reset schematic suggestion StreamUnlimited Engineering GmbH Gutheil-Schoder-G. 10, 1100 Vienna, Austria T +43-1-667 2002, F +43-1-667 2002 4401 Stream810_HW_Specification_V_2_0_20180116.docx January 16, 2018 Made For iDevice / AirPlay The Stream810 can support AirPlay, iDevice control and audio over USB. These features require the Apple authentication co-processor to be mounted externally to the Stream810 (connected via I2C). A license agreement with Apple must be in place in order to sell products that use either of these features. StreamUnlimited will provide reference schematics for interfacing to the Apple Authentication Processor to MFi licensees on request. If you are interested in using the iDevice control feature please register at https://mfi.apple.com and send us your registration confirmation. We will then forward you the reference schematics and the interface specification to the Stream810 as soon as possible. Power On/Off and Software recovery Stream810 can be powered on and off by a push button or host microcontroller using NPB_IN signal. When powered off, the module consumes less than 10mW. NPB_IN signal is connected to onboard power management IC but also sensed by software, the implementation is as follows:

When 5V comes up, the onboard power controller will activate the supplies automatically. There is no need to toggle NPB_IN in this case. NPB_IN should remain floating (a pullup resistor is included in the Stream810; do not overrule externally). See Figure 22. As soon as linux is booted (typically 30s), the NPB_IN signal is monitored by software. When NPB_IN is pulled low externally for more than 10ms but less than 1s, the Stream810 will stop playback, deregister on the network and shut down. The Stream810 will then issue a power off command to the power management IC. The complete shutdown sequence may take 10 seconds. VDD_1V8 and 3V3_OUT drops to zero volts after completion of the shutdown sequence. See Figure 23. To power the module on again without toggling 5V supply, pull the NPB_IN line low for more than 2 seconds. The power management IC will then re-enable the supplies. The NPB_IN line should be returned to High-Z state after being held low for more than 2 seconds. The power management IC includes a hard power off function similar to a PC. When the system is booted but for some reason not responsive, the Stream810 can be powered down by keeping NPB_IN low for 10 or more seconds, and simultaneously driving SYSRESETN_INOUT low. See Figure 25. Do not use this method during a software update, since the Stream810 may be unresponsive for long periods during a software update. Should it be required that the Stream810 does not boot up when 5V becomes active, keep SYSRESETN_INOUT low and pull NPB_IN low for more than 15 seconds. See Figure 24. The Stream810 will only sense NPB_IN after the Linux kernel is booted, pulling NPB_IN low within the first 30 seconds after power on may be ignored by the Stream810. Please make sure that the Linux kernel is booted before driving NPB_IN.

However, for factory-programming or to recover a module which does not boot correctly, the software image can be updated from a USB mass storage device attached to a Stream810 USB port. This method requires that the onboard flash still contains a valid bootloader. The recovery mode is triggered by pulling NPB_IN low for >3s and <10s, rather than only for 2s for normal power up. See Figure 26. Software recovery can also be initiated after the Stream810 has been powered off, see Figure 23. If no mass storage device is connected or no software image file found, the module will boot up normally. This will avoid malfunction if the NPB_IN is held low for >3s and <10s accidentally, for example if the customer keeps the power button pressed too long. NPB_IN Functionality NPB_IN is connected directly to the PWRON pin of the PMIC (Power Management IC). It is the Power On-Off key (PEK) input with an internal 100k pull-up resistor.

Modules specified for 1.2 GHz operation can be limited to 1GHz operation to be used in applications which were developed and released using 1GHz modules. Modules specified for 1GHz operation can be over-clocked to 1.2GHz for development and release activities, they should however not be used for final products since operation at 1.2GHz is not guaranteed. Contact StreamUnlimited should you wish to change the default configuration. When CPU junction temperature exceeds 85C, the operating frequency will be limited by software to 800MHz to avoid damage or reduction of lifetime. When the temperature drops below 83C again, the limit is disabled and full CPU speed becomes available.
