SiLEFM8BB31F64G-D-QFN24

Overview

The EFM8BB31F64G-D-QFN24 is a high-performance 8051-based 8-bit microcontroller from Silicon Labs Busy Bee family, operating at up to 50 MHz. It features 64 kB of flash memory, 4.25 kB of RAM, and is AEC-Q100 qualified for automotive applications. This MCU integrates flexible digital and analog peripherals, including Configurable Logic Units (CLUs) and a multi-channel ADC in a compact 4x4 mm QFN24 package.

Why Choose This Part

This MCU offers exceptional throughput for an 8051 device, reaching nearly 50 MIPS at its maximum clock speed. The integrated peripheral crossbar simplifies PCB design by allowing I/O to be mapped to any pin, while the ultra-low shutdown current of 0.91 uA enables long battery life in standby modes.

Applications

Getting Started

Engineers can begin development with the EFM8BB3 Busy Bee Starter Kit (EFM8BB3-STK). Software development is supported by Simplicity Studio, which provides a free 8051 compiler, configuration tools, and non-intrusive on-chip debugging via the C2 interface.
