Wireless Connectivity Guide Texas Instruments 4Q 2014
The CC2540 is a cost-effective, low-
power, true System-on-Chip (SoC)
solution for single-mode Bluetooth low
energy applications, including
mobile accessories, sports and
fitness, consumer health, sensors
and actuators, remote controls, HID,
proximity, and more. The CC2540
combines a 1-Mbps GFSK RF
transceiver, offering superior range
over the competition with a periph-
eral rich 8051 MCU core. This highly
integrated and low cost SoC, coupled
with TI’s Bluetooth low energy stack,
offers a true one-chip integrated
solution.
