CC2540 BLE 4.0 Bluetooth Module

CC2540 BLE 4.0 Bluetooth Module


The CC2540 is a cost-effective, low-power, true system-on-chip (SoC) for Bluetooth low energy applications. It enables robust BLE master or slave nodes to be built with very low total bill-of-material costs. The CC2540 combines an excellent RF transceiver with an industry-standard enhanced 8051 MCU, in-system programmable flash memory, 8-KB RAM, and many other powerful supporting features and peripherals. The CC2540 is suitable for systems where very low power consumption is required. Very low-power sleep modes are available. Short transition times between operating modes further enable low power consumption.

The CC2540 comes in two different versions: CC2540F128/F256, with 128 and 256 KB of flash memory, respectively.

Combined with the Bluetooth low energy protocol stack from Texas Instruments, the CC2540F128/F256 forms the market’s most flexible and cost-effective single-mode Bluetooth low energy solution.

Module Specs:

Vcc:3.3-5.0 Vdc

default baudrate:115200

TX,RX level: 3.3-5.0V tolerent

when be used with any microcontroller the module can be enable or disabled using the (EN) pin which is active low

so if you will use the module with USB-TTL module you can connect EN and RTS to GND of the module
