SiLEFM8BB10F8G-A-QFN20R
Overview
The EFM8BB10F8G-A-QFN20R is part of Silicon Labs' Busy Bee family of 8-bit microcontrollers, based on a high-speed pipelined CIP-51 8051 core. Operating at up to 25 MHz, this MCU integrates a highly flexible I/O priority crossbar and a 12-bit ADC in a compact 3x3mm QFN20 package. It is designed for simple, high-volume control tasks that require small footprints and reliable 8-bit performance.
Why Choose This Part
This MCU offers a 12-bit ADC which is uncommon in budget 8-bit devices, providing higher precision for analog sensing. The high-speed 25 MHz core and 5V-tolerant I/Os allow for easier integration into mixed-voltage systems without external level shifters. Its tiny 3x3mm QFN20 package and built-in oscillator minimize the total Bill of Materials and PCB area.
Applications
Getting Started
Development is supported by the Simplicity Studio IDE, which provides automated configuration tools and a compiler. For hardware evaluation, the EFM8BB1 LCK Low Cost Starter Kit offers a built-in debugger and access to all GPIOs. The crossbar configuration tool within the IDE simplifies the mapping of digital peripherals to the 16 available GPIO pins.
