FCC ID: EP9-TMXM05L modular

M05L User muanal 1. General Description 1.1.
Overview The RTL8762CK (hereafter referred to as the RTL8762C except where differences exist) is an ultra-low-power system on-chip solution for Bluetooth 5.0 low energy applications that combines the excellent performance of a leading RF transceiver with a low-power ARM Cortex-M4F and rich powerful supporting features and peripherals. The RTL8762C supports an analog MIC interface that integrates a sigma-delta ADC, programmable gain amplifier, 5-Band equalizer and microphone bias circuit for voice command application. The RTL8762C embeds IR transceiver, hardware key-scan, and Quad-decoder on a single IC, and is provided in a QFN package. 1.2. MCU Platform The embedded ARM Cortex-M4F 32-bit CPU features a 16-bit instruction set with 32-bit extensions (Thumb-2 technology) that delivers high-density code with a small memory footprint. By using a single-cycle 32-bit multiplier, a 3-stage pipeline, and a Nested Vector Interrupt Controller (NVIC), the ARMCortex-M4F makes program execution simple and highly efficient. Serial Wire Debug (SWD) interface provided as part of the Debug Access Port (DAP), in conjunction with the Basic Branch Buffer (BBB). This offers a flexible and powerful mechanism for non-intrusive program code debugging. Developers can easily add breakpoints in the code and perform single-step debugging. The RTL8762C memory architecture includes ROM, 160kByte RAM and 8MByte Flash Address Space. The 160kByte RAM consists of RAM1 (112kByte Data RAM), RAM2 (8kByte Cache Shared RAM), RAM3 (8kByte Cache Shared RAM), and RAM4 (32kByte Buffer RAM). All the RAM regions can be used to execute code and hold data. Flash Address Space is a virtual space which is mapped to external Flash to extend the code space in XIP (eXecute In Place) mode. 2.

-20C to +60C FCC Regulatory notices Modification statement Timex Group USA, Inc. has not approved any changes or modifications to this device by the user. Any changes or modifications could void the users authority to operate the equipment. Interference statement This device complies with Part 15 of the FCC Rules and Industry Canada licence-exempt RSS standard(s). Operation is subject to the following two conditions: (1) this device may not cause interference, and (2) this device must accept any interference, including interference that may cause undesired operation of the device. RF exposure This equipment complies with FCC and ISED radiation exposure limits set forth for an uncontrolled environment. The antenna should be installed and operated with minimum distance of 20 cm between the radiator and your body. Antenna gain must be below 3 dBi. This transmitter must not be co-located or operating in conjunction with any other antenna or transmitter. The host end product must include a user manual that clearly defines operating requirements and conditions that must be observed to ensure compliance with current FCC RF exposure guidelines. For portable devices, in addition to above, a separate approval is required to satisfy the SAR requirements of FCC Part 2.1093. If the device is used for other equipment that separate approval is required for all other operating configurations, including portable configurations with respect to 2.1093 and different antenna configurations. FCC Class B digital device notice This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures:

Reorient or relocate the receiving antenna. Increase the separation between the equipment and receiver. Connect the equipment into an outlet on a circuit different from that to which the receiver is connected. Consult the dealer or an experienced radio/TV technician for help. Labelling Requirements for the Host device The host device shall be properly labelled to identify the modules within the host device. The certification label of the module shall be clearly visible at all times when installed in the host device, otherwise the host device must be labelled to display the FCC ID and ISED of the module, preceded by the words

"Contains transmitter module", or the word "Contains", or similar wording expressing the same meaning, as follows:

Model: WIFI module Contains FCC IDEP9-TMXM05L The host OEM user manual must also contain clear instructions on how end users canfind and/or access the module and the FCC ID and ISED. Model: WIFI module Contains FCC IDEP9-TMXM05L OEM Statement a. The module manufacturer must show how compliance can be demonstrated only for specific host or hosts b. The module manufacturer must limit the applicable operating conditions in which t transmitter will be used, and c. The module manufacturer must disclose that only the module grantee can make the te evaluation that the module is compliant in the host. When the module grantee either refuses to make this evaluation, or does not think it is necessary, the module certification is rendered invalid for use in the host, and the host manufacturer has no choice other than to use a different module, or take responsibility ( 2.929) and obtain a new FCC ID for the product. d. The module manufacturer must provide the host manufacturer with the followi requirements:

i. The host manufacturer is responsible for additional testing to verify compliance as composite system. When testing the host device for compliance with Part 15 Subpart B, the host manufacturer is required to show compliance with Part 15 Subpart B while the transmitter module(s) are installed and operating. The modules should be transmitting and the evaluation should confirm that the modules intentional emissions are compliant (i.e. fundamental and out of band emissions). Part 15 Subpart C Section 15.249 The EUT uses external antenna, antenna gain: 0 dBi. There is no restriction on the installation method. EP9-TMXM05L The EUT uses external antenna, antenna gain: 0 dBi. EP9-TMXM05L
