Overview

The BM70BLES1FC2-0B05BA is a shielded Bluetooth Low Energy (BLE) 5.0 module from Microchip Technology featuring an integrated chip antenna and a complete onboard software stack. It is designed to simplify adding wireless connectivity to embedded systems via a standard UART interface, operating within a 1.9V to 3.6V range. The module includes 256kB of Flash memory and supports a wide array of peripherals including a 12-bit ADC, PWM, and multiple serial interfaces.

Why Choose This Part

The module is fully shielded and regulatory certified, which significantly reduces RF design complexity and time-to-market. It features a very low shutdown current of 2.9uA and supports a versatile 1.9V to 3.6V supply range, making it ideal for direct operation from coin cell batteries.

Applications

Secure Payment Terminals
Utilizes the integrated BLE stack for secure, low-power data transmission in point-of-sale systems.
Industrial IoT Sensors
Monitors remote hardware using the 8-channel, 12-bit ADC and transmits data to gateways via BLE.
Wearable Health Monitors
Leverages the small 12x22mm form factor and 60uA sleep current for battery-operated medical devices.
Home Automation Controllers
Acts as a bridge between smartphone apps and household appliances using I2C and GPIO controls.
