Product details
Overview
CC2640R2FRSMR 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 supports BLE Coded PHY (Long Range), 2-Mbit PHY (High Speed), and operates from 1.8–3.8 V with standby current of 1.1 µA - deployed in smart locks, asset trackers, and medical sensors.
For engineers reviewing the CC2640R2FRSMR datasheet, CC2640R2FRSMR pinout, CC2640R2FRSMR application, or CC2640R2FRSMR equivalent, key selection criteria include its 4×4-mm VQFN32 package with 10 GPIOs, integrated DC/DC converter, BLE 5.1 protocol stack in ROM, and autonomous sensor controller enabling sub-µA sensing duty cycles.
Technical Context
The CC2640R2FRSMR implements a dual-core architecture: an Arm Cortex-M3 main CPU handles application and BLE stack execution, while a separate Arm Cortex-M0 radio controller manages RF PHY layer timing and modulation. Its sensor controller is a 16-bit autonomous engine with 2 KB SRAM, capable of running ADC sampling at 1 Hz with only 1 µA system current.
RF performance includes –97 dBm BLE sensitivity, +5 dBm programmable output power, and compliance with FCC Part 15, ETSI EN 300 328, and ARIB STD-T66. The device uses a 24-MHz crystal oscillator for RF timing and a 32.768-kHz crystal for RTC, with internal DC/DC conversion supporting efficient operation across the full 1.8–3.8 V supply range.

FAQ
What Bluetooth 5.1 features does the CC2640R2FRSMR support?
The CC2640R2FRSMR supports all mandatory and key optional Bluetooth 5.1 Low Energy features, including LE Coded PHY (S=2/S=8 for Long Range), LE 2-Mbit PHY (High Speed), Advertising Extensions, and Multiple Advertisement Sets. It maintains full backward compatibility with Bluetooth 4.x and earlier specifications. These capabilities are enabled by the ROM-resident BLE stack included in the SimpleLink CC2640R2F SDK, and verified per Bluetooth SIG qualification ID QDID 102812.
Does the CC2640R2FRSMR include an integrated DC/DC converter?
Yes, the CC2640R2FRSMR integrates a buck DC/DC converter with dedicated power terminals (DCDC_SW, VDDR, VDDR_RF, VDDS_DCDC). This allows direct connection to a single 1.8–3.8 V supply while generating regulated 1.7–1.95 V rails for core and RF domains - reducing external component count and improving efficiency over LDO-only designs. The converter is fully configurable via software and supports seamless transition between DC/DC and LDO modes.
How many GPIOs does the CC2640R2FRSMR provide in its RSM package?
The CC2640R2FRSMR in the 4-mm × 4-mm VQFN32 (RSM) package provides 10 GPIOs: DIO_0 through DIO_9. All are software-configurable for digital I/O, analog input (with ADC/MUX support), UART/I²C/SSI peripheral assignment, and sensor controller interface. Unlike larger packages (e.g., RGZ with 31 GPIOs), the RSM variant prioritizes minimal footprint over I/O count - ideal for size-constrained BLE endpoints.
Is the CC2640R2FRSMR pin-compatible with other SimpleLink devices?
Yes, the CC2640R2FRSMR is pin-compatible with the CC2640, CC2650, and CC1350 in the same 4-mm × 4-mm VQFN32 (RSM) package. This enables hardware reuse across BLE-only, multi-protocol (BLE + Zigbee/Thread), and Sub-1 GHz + BLE designs. However, it is not pin-compatible with the 5-mm × 5-mm RHB or 7-mm × 7-mm RGZ variants of the CC2640R2F family due to differing pin counts and layouts.
What development tools support the CC2640R2FRSMR?
The CC2640R2FRSMR is supported by TI's complete SimpleLink™ ecosystem: Code Composer Studio™ IDE, IAR Embedded Workbench®, SmartRF™ Studio for RF configuration, Sensor Controller Studio for autonomous sensor firmware, and the CC2640R2 LaunchPad™ Development Kit (LP-CC2640R2). The SimpleLink CC2640R2F SDK includes certified BLE 5.1 protocol stack, driver libraries, and reference examples - all optimized for the RSM package's memory and peripheral constraints.
