Texas Instruments (TI) licensed solution provider RF-star Technology recently released the 2.4GHz multi-protocol module RF-BM-2651B1.This module is developed based on Texas Instruments' SoC CC2651R3 and supports Thread, Zigbee 3.0, Bluetooth®5.2 Low Energy, IEEE 802.15.4g, TI 15.4-Stack (2.4 GHz) and proprietary protocols.CC2651R3 contains 48 MHz ARM® Cortex®-M4F main processor, 40 KB RAM, 352 KB Flash, suitable for Zigbee, Thread networking and Bluetooth low energy applications，It is optimized for low-power wireless communication and advanced sensing scenarios, and can be widely used in power grid infrastructure, building automation, retail automation, personal electronics and medical applications.

In addition to the high-performance ARM Cortex M4 processor in charge of application logic, the main chip of the module also integrates an ARM Cortex-M0 processor dedicated to radio frequency management, supporting multiple physical layers and radio frequency standards.The module has 352 KB of programmable flash memory, 32 KB of ultra-low leakage SRAM and 8 KB of cache SRAM, on-board industrial-grade 48MHz crystal oscillator and 32.768kHz low-power clock crystal oscillator, meeting the needs of various solutions.

Compared with TI CC2652 series multi-protocol modules, the Flash 352 KB of CC2651 series modules remains unchanged.

The RAM is reduced from 88 KB to 40 KB, the sensor controller is removed, and the RF direction finding (Direction Finding) function is not supported. In terms of multi-protocol, it still supports Thread, Zigbee, BLE 5.2, IEEE 802.15.4g, TI 15.4- Stack (2.4 GHz) and proprietary protocol systems are suitable for customers who are more cost-sensitive.
