CC2540F256RHAR Description

Short technical summary and product information.

The Texas Instruments CC2540F256RHAR is a true single-chip solution for Bluetooth Low Energy (BLE) applications, also supporting USB connectivity. This device integrates a high-performance, low-power 8051 microcontroller core with a 2.4GHz RF transceiver, making it suitable for a wide range of wireless applications.

 

Key electrical specifications include a wide operating voltage range of 2V to 3.6V, with active mode current consumption as low as 19.6mA for RX and 24mA for TX at -6 dBm. It offers a maximum output power of 4dBm and a receiver sensitivity of -93dBm, with an excellent link budget of up to 97dB enabling long-range communication.

 

The microcontroller features 256KB of in-system-programmable Flash memory and 8KB of SRAM. Peripherals include a 12-bit ADC with eight channels and configurable resolution, SPI, USART, and USB interfaces, along with 21 GPIO pins.

 

Packaged in a 40-VQFN (6x6mm) format, the CC2540F256RHAR is designed for surface mount applications and operates within a temperature range of -40°C to 85°C. It is compatible with worldwide radio frequency regulations including ETSI EN 300 328 and FCC CFR47 Part 15.
