1 Device Overview

1.1 Description

RF-BM-2652P2(I) is an RF module based on TI lower-power CC2652P SoC, which is a multiprotocol 2.4 GHz wireless

module supporting Thread, Zigbee®, Bluetooth®5.3 Low Energy, IEEE 802.15.4, IPv6-enabled smart objects

(6LoWPAN), proprietary systems, including the TI 15.4-Stack (2.4 GHz), and concurrent multiprotocol through a

Dynamic Multiprotocol Manager (DMM) driver. It integrates a 48 MHz crystal and a 32.768 kHz crystal, 352 KB of

in-system Programmable Flash, 256 KB ROM, 8 KB of Cache SRAM, and 80 KB of ultra-low leakage SRAM. Its ARM®

Cortex®-M4F core application processor can operate at an extremely low current at flexible power modes. And the

module enables long-range and low-power applications using an integrated +20 dBm high-power amplifier with

best-in-class transmit current consumption at 85 mA. It features a small size, robust connection distance, and rigid

reliability. Optional antenna output modes (PCB, IPEX connector, and half-hole interface) make the module more

convenient for application and development.
