Product Introduction

RF-BM-2642B1 is a Bluetooth 5.0 module independently developed based on Texas Instruments CC2642R as the core. In addition to integrating a high-performance ARM Cortex-M4F processor responsible for application logic and an ARM Cortex-M0 processor dedicated to the RF core, the module also features a distinctive 16-bit low-power sensor processing core. It has 352 KB of programmable flash memory and 80 KB of ultra-low leakage RAM (SRAM). It supports Bluetooth Low Energy 5.0 and is backward compatible with Low EnergyBluetooth 4.2, etc.

The module has all I/Os brought out and complies with FCC, CE, and RoHS regulations for RF and electromagnetic compatibility, meeting export requirements. The module integrates an industrial-grade 48 MHz crystal oscillator and a 32.768 kHz low-power clock crystal. It includes various peripherals such as I2C, I2S, UART, SPI, ADC, and GPIO.
