EFM8UB20F32G-B-QFN32 Description

Short technical summary and product information.

The EFM8UB20F32G-B-QFN32 is an 8-bit microcontroller from Silicon Labs' Universal Bee family, designed for multi-purpose embedded applications with USB functionality. It features a pipelined CIP-51 8051 core capable of operating at a maximum frequency of 48MHz.

 

This MCU offers 32KB of FLASH program memory and 2.25KB of RAM. It includes essential peripherals such as 2 UARTs, SPI, 2 SMBus/I2C serial communications, a 10-bit ADC, and two analog comparators. The device supports crystal-less full-speed USB 2.0 compliant controller with a 1KB buffer.

 

With up to 25 multifunction I/O pins, it provides flexibility for various designs. The operating voltage ranges from 2.65V to 3.6V, and it operates within a temperature range of -40°C to 85°C. The microcontroller is housed in a 32-QFN (5x5) package and is designed for surface mount.

 

Key features include an internal 48MHz precision oscillator with ±0.25% accuracy when USB clock recovery is active, making it suitable for USB and UART operations without external components. It also includes power management features like an internal LDO regulator, brown-out detector, and power-on reset.
