EFM8UB Universal Bee Microcontrollers, Silicon Labs


The Universal Bee Microcontroller (MCU) family are designed for USB applications. Operating at up 50 MHz with a pipelined 8-bit C8051 core.

Up to 22 multifunction, 5 V tolerant I/O pins
Low energy USB support
Priority crossbar for flexible pin mapping
12-bit Analogue to Digital converter (ADC)and 2 analogue comparators with internal voltage DAC as reference input
5 16-bit timers
Integrated temperature sensor
2 UARTs, SPI and SMBus/I2C master/slave and I2C slave


The EFM8 8-bit microcontroller family has an unparalleled combination of features and capabilities including a high-speed pipelined 8051 core, ultra-low power, precision analogue and enhanced communication peripherals, integrated oscillators, small-footprint packages, and a crossbar architecture that enables flexible digital and analogue multiplexing to simplify PCB design and I/O signal routing. These next-generation 8-bit devices are aimed at the engineer developing products for the Internet-of-Things (IoT) which will be very small, perform complex processing and run off tiny batteries.
