SiLBGM123A256V2R
Overview
The BGM123A256V2R is a high-performance Bluetooth Low Energy (BLE) System-in-Package (SiP) module from Silicon Labs, measuring just 6.5 x 6.5 mm. It integrates a 2.4 GHz transceiver, an ARM Cortex-M4 core with a floating-point unit (FPU), and a built-in antenna into a single compact package. With 256 kB of flash and 32 kB of RAM, it provides a complete wireless solution for space-constrained applications.
Why Choose This Part
This module offers a significant space advantage by integrating the antenna and all necessary timing crystals into a SiP, reducing the PCB footprint by up to 90 percent compared to discrete designs. It features an ultra-low sleep current of 2.5 uA and a high-efficiency DC-DC converter, making it suitable for devices running on coin cell batteries.
Applications
Getting Started
Developers should use the Silicon Labs Simplicity Studio IDE, which provides the Bluetooth SDK and configuration tools. For hardware evaluation, the Wireless Gecko Starter Kit (SLWSTK6101C) with a BGM123 radio board is the standard entry point. The module's pre-certified radio stack simplifies the regulatory approval process for FCC, IC, and CE compliance.
