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) t hat delive rs high-dens ity code w ith a small memory footpr int.
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), an d 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 th e code space
in XIP (eXecute In Place) mode.

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 user’s 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-loc

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.

ated or operating in conjunction with any other antenna or transmitter.

• 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 ID：EP

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

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 module’s 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.

The EUT uses external antenna, antenna gain: 0 dBi.
