A high degree of integration enables very low system costs requiring only a single 3.3V power input, a 38.4 MHz crystal, and SPI Flash. The RF path needs only a lowpass filter for antenna connection. The SoC includes a full-featured W LAN subsystem powered by proven and mature IEEE 802.11n/g/b Marvell technology. The WLAN subsystem integrates a WLAN MAC, baseband, and direct-conversion RF radio with integrated PA, LNA, and transmit/receive switch. It also integrates a CPU subsystem with integrated memory to run Marvell WLAN firmware to handle real time WLAN protocol processing to off-load many WLAN functions from the main application CPU. The 88MW300/302 application subsystem is powered by an ARM Cortex-M4F CPU that operates up to 200 MHz. The device supports an integrated 512 KB SRAM, 128 KB mask ROM, and a QSPI interface to external Flash. An integrated Flash Controller with a 32 KB SRAM cache enables eXecute In Place (XIP) support for firmware from Flash. am1uypvwincml8vcyp7azhga8189kcblgwl8g12a4v3hp-iob1swd7 * Global Network Lighting & Con MARVELL CONFIDENTIAL, UNDER NDA# 12150208 1uypvwincml8vcyp7azhga8189kcblgwl8g12a4v3hp-iob1swd7 * Global Network Lighting & Control In MARVELL CONFIDENTIAL, UNDER NDA# 12150208 The SoC is designed for low-power operation and includes several low-power states and fast wake-up times. Multiple power domains and clocks can be individually shut down to save power. The SoC also has a high-efficiency internal PA that can be operated in low-power mode to save power. The microcontroller and WLAN subsystems can be placed into low-power states, independently, supporting a variety of application use cases. An internal DC-DC regulator provides the 1.8V rail for the WLAN subsystem. The SoC provides a full array of peripheral interfaces including SSP/SPI/I2S (3x), UART (3x), I2C (2x), General Purpose Timers and PWM, ADC, DAC, Analog Comparator, and GPIOs. It also includes a hardware cryptographic engine, RTC, and Watchdog Timer. The 88MW302 includes a high speed USB On-The-Go
(OTG) interface to enable USB audio, video, and other applications. A complete set of digital and analog interfaces enable direct interfacing for I/O avoiding the need for external chips. The application CPU can be used to support custom application development avoiding the need for another microcontroller or processor. Figure 1 shows an overall block diagram of the device. 7 d w s 1 b o i
