Product details
Overview
CC2640R2FRSMT 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, and a dedicated ultra-low-power sensor controller. It delivers -97 dBm RX sensitivity, +5 dBm programmable TX output, and 1.1 µA standby current with full RAM retention - enabling multi-year battery life in compact IoT edge nodes like smart locks and medical sensors.
For engineers reviewing the CC2640R2FRSMT datasheet, CC2640R2FRSMT pinout, CC2640R2FRSMT application, or CC2640R2FRSMT equivalent, key selection criteria include its VQFN32 (4 mm × 4 mm) package with 10 GPIOs, integrated DC/DC converter, Bluetooth 5.1 LE Coded PHY support, and autonomous sensor controller capable of 1-Hz ADC sampling at 1 µA system current.
Technical Context
The CC2640R2FRSMT implements a dual-core architecture: the Arm Cortex-M3 handles application and BLE stack execution, while a separate Arm Cortex-M0 core manages RF protocol timing and modulation. Its RF subsystem supports Bluetooth 5.1 LE Coded PHY (125/500 kbps), 2-Mbps GFSK, and advertising extensions - all compliant with FCC Part 15, ETSI EN 300 328, and ARIB STD-T66.
Power management integrates an on-chip DC/DC converter, ultra-low-leakage SRAM (20 KB), and a programmable sensor controller with 2 KB SRAM that operates independently of the main CPU. Peripherals include a 12-bit 200-ksps ADC, AES-128, TRNG, RTC, UART/I²C/I²S, and two SSI interfaces - all routable to any GPIO via flexible pin mapping.

Does the CC2640R2FRSMT include an integrated DC/DC converter?
Yes, the CC2640R2FRSMT integrates a high-efficiency DC/DC converter with dedicated SW, VDDR, VDDR_RF, and DCOUPL pins. This allows direct regulation from 1.8–3.8 V input to 1.7–1.95 V core/RF rails, achieving >85% efficiency and reducing external component count. The converter is enabled by default and supports seamless transition between LDO and DC/DC modes based on load conditions.
How many GPIOs are available on the CC2640R2FRSMT package?
The CC2640R2FRSMT uses the RSM VQFN32 (4 mm × 4 mm) package and provides 10 user-configurable GPIOs. These pins support digital I/O, analog input (ADC, comparator), capacitive sensing, UART, I²C, SPI, and JTAG debugging - all fully routable to any peripheral function via software configuration without hardware changes.
What is the role of the sensor controller in the CC2640R2FRSMT?
The sensor controller in the CC2640R2FRSMT is a dedicated 16-bit autonomous processor with 2 KB SRAM, capable of running independent firmware while the main Cortex-M3 remains in deep sleep. It directly interfaces with the 12-bit ADC, comparators, and current source - enabling ultra-low-power tasks like 1-Hz temperature sampling at 1 µA system current, eliminating wake-up latency and MCU power overhead.
Is the CC2640R2FRSMT pin-compatible with other SimpleLink devices?
The CC2640R2FRSMT is pin-compatible with the CC2640 and CC2650 in all VQFN packages, and with the CC1350 in 4-mm × 4-mm and 5-mm × 5-mm VQFN packages. However, pin compatibility does not imply identical peripheral routing or register mapping - firmware must be validated per device. The RSM package shares pinout with CC2640R2FRHB but differs from RGZ/RSM/YFV variants.
