EFM8 Universal Bee Family
EFM8UB2 Data Sheet
The EFM8UB2, part of the Universal Bee family of MCUs, is a
multi-purpose line of 8-bit microcontrollers with USB feature set.
These devices offer high value by integrating a USB peripheral interface with a high precision oscillator, clock recovery circuit, and integrated transceiver, making them ideal for
any full speed USB applications with no external components required. With an efficient
8051 core and precision analog, the EFM8UB2 family is also optimal for embedded applications. • Pipelined 8-bit 8051 MCU Core with 48
MHz maximum operating frequency
• Up to 40 multifunction I/O pins
• Crystal-less full speed/low speed USB 2.0
compliant controller with 1 KB buffer
memory
• One differential 10-bit ADC and two analog
comparators EFM8UB2 applications include the following:
• Consumer electronics
• Medical equipment • USB I/O controls, dongles
• High-speed communication bridge KEY FEATURES • Internal 48 MHz oscillator with ±0.25%
