It carries 128 KB of Flash and 20 KB of RAM, enough for a BLE stack plus a small application on a single chip. The part is built for low-power wireless sensor nodes, beacons, and portable medical devices where battery life matters — receive current sits at 5.9 mA and transmit at 9.1 mA at 5 dBm output. ## 10 GPIOs and serial interfaces for sensor integration With 10 GPIOs and a set of serial interfaces including I²C, I²S, SPI, and UART, this part can talk to most common sensors, codecs, and peripherals without extra glue logic. The 32-VFQFN package with exposed pad (4x4 mm) keeps the board footprint small — useful for space-constrained designs like a wearable or a coin-cell-powered tag. Supply voltage spans 1.8 V to 3.8 V, so it runs directly from a single Li-ion cell or two alkaline batteries. ## 5 dBm TX power and -97 dBm sensitivity The transmitter puts out 5 dBm — about 3 dB more than the typical 0 dBm BLE part — which translates to roughly 40% extra range in free space, or better margin through walls in a factory or warehouse. The receiver sensitivity of -97 dBm is solid for a 2 Mbps data rate; it keeps the link alive at the far edge of range where cheaper parts start dropping packets. If your design needs reliable communication across a few tens of metres indoors, this part gives you headroom.","metaTitle":"CC2640R2FRSMT SimpleLink Bluetooth 5.1 MCU, 2.4 GHz","metaDescription":"Texas Instruments CC2640R2FRSMT is a Bluetooth 5.1 wireless MCU with 128 KB Flash, 20 KB RAM, 5 dBm output, -97 dBm sensitivity.
