EFM8™ Universal Bee 8-bit Microcontrollers (MCUs)
The Universal Bee family of EFM8™ microcontrollers (MCUs) is ideal for space constrained USB applications. Universal Bee MCUs operate at up to 48 MHz and the family includes devices with a low-power USB 2.0 peripheral interface, charger detect circuit, 8 kV ESD protection, and enhanced high-speed communication interfaces.
Universal Bee Common Specs
- Pipelined 8-bit C8051 core with 48 MHz maximum operating frequency
- 5 V tolerant I/O pins
- Low Energy USB with full- and low-speed support saves 60% of the USB power consumption
- USB charger detect circuit (USB-BCS 1.2 compliant)
- 12-bit ADC
- Two analog comparators with internal voltage DAC for reference
- 16-bit timers
- UARTs, SPI, SMBus/I²C master/slave and I²C slave
- Priority crossbar for flexible pin mapping
