EFM8SB Sleepy Bee Microcontrollers, Silicon Labs


The Sleepy Bee Microcontroller (MCU) family are deigned for low power and battery powered systems. Operating at up to 25 MHz with short wakeup times and low power consumption in both active and sleep modes.

8051 MCU core
Integrated temperature sensor
Integrated LDO maintains low active current at all voltages
Up to 14 capacitive sense channels
UART and I2C
4 16-bit timers


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.
