Product Introduction

The CC2540F256RHAR is a cost-effective, low-power, true system-on-chip (SoC) suitable for low-power Bluetooth applications. It can build a powerful BLE master node or slave node at a very low total bill of materials cost.

The CC2540F256RHAR combines an outstanding RF transceiver with an industry-standard enhanced 8051 MCU, in-system programmable flash memory, 8KB RAM, and many other powerful support functions and peripherals. The CC2540F256RHAR is suitable for systems that require extremely low power consumption. Provide a very low-power sleep mode. The short conversion time between working modes further achieves low power consumption.

The CC2540F256RHAR, combined with the low-power Bluetooth protocol stack of Texas Instruments, constitutes the most flexible and cost-effective single-mode low-power Bluetooth solution on the market.

Application field

The CC2540F256RHAR is suitable for systems requiring ultra-low power consumption, including:

2.4GHz Bluetooth Low Energy System

Mobile phone accessories

Sports and leisure equipment

Consumer electronic products

Human-machine interface products (keyboards, mice, remote controls)

USB encryption dog

Health and Medical Care

Its low power consumption design and short mode transition time make the CC2540F256RHAR excel in these applications ‌.
