EFM8™ Laser Bee 8-bit Microcontrollers (MCUs)

The Laser Bee family of EFM8 microcontrollers (MCUs) includes analog intensive MCUs that operate at up to 72 MHz. These MCUs offer high performance analog including 14-bit ADC, 12-bit DAC, ±3 °C temperature sensor and high speed communication peripherals in packages as small as 3 mm x 3 mm, making them ideal for applications that require performance analog.

Core frequency
72 MHz
High performance integration
14-bit ADC, 4 x 12-bit DACs
