EFM8BB21F16G-C-QFN20R 8-bit MCU | 50MHz | 16KB Flash | 20-QFN | Silicon Labs Busy Bee

In motor control, sensor nodes, or portable consumer electronics, selecting an 8-bit MCU that offers sufficient performance and ease of development is key to rapid project delivery. The EFM8BB21F16G-C-QFN20R is a high-performance 8-bit microcontroller from Silicon Labs' Busy Bee family, packing powerful features into a compact 3x3mm QFN package. Powered by a pipelined CIP-51 8051 core running at up to 50MHz, it features 16KB Flash and 2.25KB RAM. Rich peripherals include a 12-bit ADC, two analog comparators, 3-channel PWM/PCA, and multiple communication interfaces including UART, SPI, and I2C. Its flexible priority crossbar allows functions to be mapped to 16 I/O pins, simplifying PCB layout. The device operates from 2.2V to 3.6V across -40°C to +85°C, and comes in Tape & Reel packaging (1,500/reel). We supply 100% original, new products with ample stock and fast delivery.
