It carries 128kB of Flash and 28kB of SRAM, enough to run a BLE stack and a moderate application without external memory. The RF front end delivers a -103dBm sensitivity and a 5dBm output power, giving a link budget that works through a couple of interior walls in a smart-home or beacon deployment. ## Power budget and battery life Current draw sits at 5.9mA in receive and 9.1mA in transmit at 5dBm output. For a coin-cell-powered sensor that wakes, sends a packet, and goes back to sleep, those numbers keep the average current low enough for multi-year operation with a CR2032. Supply range from 1.8V to 3.8V means the part runs directly off a lithium primary cell or a 3.3V rail without an extra regulator. ## GPIO and serial interface count Fifteen GPIOs are available, which covers a typical sensor node with an I²C accelerometer, a SPI flash, a UART for debug, and a couple of button/LED lines. The serial interfaces include I²C, I²S, SPI, and UART, so audio streaming or external codec connection is possible without bit-banging.","metaTitle":"CC2640R2FRHBR Bluetooth v5.0 MCU, 128kB Flash, 28kB SRAM","metaDescription":"Texas Instruments CC2640R2FRHBR SimpleLink™ wireless MCU with Bluetooth v5.0, 128kB Flash, 28kB SRAM, -103dBm sensitivity, 5dBm output.
