Product details
Overview
CC2640R2FRHBR from Texas Instruments is a Bluetooth® 5.1 Low Energy wireless microcontroller integrating an Arm® Cortex®-M3 CPU (48 MHz), 128 KB Flash, 20 KB SRAM, 2.4-GHz RF transceiver with –97 dBm sensitivity, and autonomous ultra-low-power sensor controller. It delivers 5.9 mA RX current, 1.1 µA standby with RTC and RAM retention, and supports over-the-air upgrades for secure firmware updates in battery-powered IoT edge nodes.
For engineers reviewing the CC2640R2FRHBR datasheet, CC2640R2FRHBR pinout, CC2640R2FRHBR application, or CC2640R2FRHBR equivalent, this page provides verified package mapping (5-mm × 5-mm RHB VQFN32), confirmed pin functions including RF_P/RF_N, DIO_0–DIO_14, RESET_N, and JTAG_TMSC/TCKC, plus real-world BLE 5.1 use cases in medical wearables and industrial asset tracking.
Technical Context
The CC2640R2FRHBR implements a dual-core architecture: the Arm Cortex-M3 handles application logic and BLE protocol stack execution, while a dedicated Arm Cortex-M0 core manages RF PHY layer operations-including LE Coded PHY (Long Range) and LE 2-Mbit PHY (High Speed)-enabling concurrent high-speed data transfer and low-latency sensor processing.
Its integrated sensor controller operates autonomously with 2 KB SRAM and ultra-low leakage, enabling sub-µA wake-up and 1-Hz ADC sampling without waking the main CPU. The on-chip DC/DC converter supports 1.8–3.8 V input and supplies separate VDDR (1.7–1.95 V) and VDDR_RF rails for optimized RF efficiency and digital logic stability.
