The RC6621A Module is a power-optimized true system-on-chip (SoC)

solution for both Bluetooth low energy and proprietary 2.4-GHz applications. It

integrates a high performance and low power RF transceiver with Bluetooth

baseband and rich peripheral IO extension. It targets 2.4-GHz Bluetooth low

energy systems, proprietary 2.4-GHz systems, Human-Interface Devices (keyboard,

mouse, and remote control), sports and leisure equipment, mobile phone

accessories and consumer electronics.

RC6621A on-chip Bluetooth system compliant with version 5.1, support all of

Bluetooth standard 5.1 feature.

The chip integrates up to 64Mhz high-performance MCU, DMA, GPIO, I2S,

I2C, SPI, UART, TIMER, RTC, watch dog, supports 32Mhz external crystal,

integrates multi-purpose 12 bit ADC.

The RC6621A integrates on chip 48KB ROM, 64K SRAM and supports user

defined IDE system, on chip SFLASH MCU development and JTAG software

upgrade.

FCC WARNING FCC Caution: Any changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate this equipment. This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation.

when the module is installed inside another device, the user manual of this device must contain below warning statements; 1. This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1)This device may not cause harmful interference. (2)This device must accept any interference received, including interference that may cause undesired operation. 2.

module manufacturer reviews detailed test data or host designs prior to giving the host manufacturer approval. This limited module procedure is also applicable for RF exposure evaluation when it is necessary to demonstrate compliance in a specific host. The module manufacturer must state how control of the product into which the modular transmitter will be installed will be maintained such that full compliance of the product is always ensured.

The module manufacturers shall provide a list of acceptable unique connectors. Explanation: The EUT has one PCB antenna, the antenna can be replaced by other authorized antennas, and the gain of each replacement antenna is no more than 1.06dBi 2.8 Label and compliance information Grantees are responsible for the continued compliance of their modules to the FCC rules.

as being Part 15 Subpart B compliant (when it also contains unintentional-radiator digital circuity), then the grantee shall provide a notice stating that the final host product still requires Part 15 Subpart B compliance testing with the modular transmitter installed. Explanation: The module without unintentional-radiator digital circuity, so the module does not require an evaluation by FCC Part 15 Subpart B. The host shoule be evaluated by the FCC Subpart B.
