The CC2540F256RHAR from Texas Instruments (TI) is a low-power Bluetooth Low Energy (BLE) wireless microcontroller designed for wireless connectivity and embedded applications. It integrates a 2.4GHz RF transceiver, an enhanced 8051 microcontroller, 256KB of in-system programmable Flash memory, and 8KB of RAM into a single-chip solution.
The device features 21 general-purpose I/O pins and a range of integrated peripherals, including a full-speed USB interface, ADC, timers, SPI, and UART interfaces. Its integrated BLE protocol stack supports the development of compact wireless systems without requiring a separate dedicated Bluetooth controller.
Operating from a 2V to 3.6V supply voltage, the CC2540F256RHAR offers low-power operating modes that help reduce energy consumption in battery-powered products. The 40-pin VQFN package, measuring 6mm × 6mm, is suitable for space-constrained PCB designs.
This wireless MCU is suitable for Bluetooth-enabled peripherals, USB dongles, wireless sensors, consumer electronics, remote controls, and other low-power wireless devices.
