EFM8BB51F16G-C-QFN20R 8-Bit Microcontroller | 50MHz | 16KB Flash | QFN-20 Package | Silicon Labs

The EFM8BB51F16G-C-QFN20R is a versatile 8-bit microcontroller from Silicon Labs' EFM8 Busy Bee family, featuring an efficient CIP-51 8051 core running up to 50MHz. It integrates 16KB of Flash memory and 1.25KB of RAM, sufficient for most embedded control tasks. The standout feature of this device is its integration of rich analog and digital peripherals—including a 12-bit ADC, multi-channel PWM, and Configurable Logic Units—into a tiny 3x3mm QFN-20 package, making it ideal for PCB space-constrained applications. It operates from 1.8V to 5.5V across an industrial temperature range of -40°C to +85°C. We supply 100% original, new products with ample stock and fast delivery.
