CC2540 Description

Short technical summary and product information.

The Texas Instruments CC2540 is a true single-chip Bluetooth Low Energy (BLE) solution designed for 2.4-GHz wireless applications. It features a high-performance, low-power 8051 microcontroller core, enabling it to run both application code and the BLE protocol stack simultaneously. With up to 256 KB of in-system-programmable Flash and 8 KB of SRAM, it offers ample memory for complex designs.

 

The CC2540 boasts excellent RF performance with a link budget of up to 97 dB, facilitating long-range applications. It includes a 12-bit ADC with eight channels, general-purpose timers, 21 GPIO pins, and a full-speed USB interface. Its low-power modes are optimized for battery-operated devices, with active RX current down to 19.6 mA and sleep modes consuming as little as 0.4 µA.

 

This device is suitable for systems targeting compliance with worldwide radio frequency regulations, including ETSI EN 300 328 and EN 300 440 Class 2 (Europe), FCC CFR47 Part 15 (US), and ARIB STD-T66 (Japan). The CC2540 is available in a compact 6-mm × 6-mm QFN40 package, making it ideal for space-constrained designs.
