C8051F042-GQ Description

Short technical summary and product information.

The C8051F042-GQ is a high-performance 8-bit microcontroller from Silicon Labs based on the 8051 core. It operates at up to 25 MHz with a pipelined instruction architecture achieving 25 MIPS throughput. The device features 64 KB of in-system programmable Flash memory and 4.25 KB of internal data RAM.

 

This microcontroller is equipped with a rich set of analog peripherals including a 10-bit SAR ADC with 13 channels and an 8-bit SAR ADC with 8 channels, as well as two 12-bit DACs. It also includes a temperature sensor, three analog comparators, and a precision voltage reference. Digital peripherals include 64 I/O pins, multiple communication interfaces such as CANbus, SMBus/I2C, SPI, and UART/USART, and a PWM module.

 

The C8051F042-GQ is designed for surface-mount assembly in a 100-TQFP package (14x14 mm). It operates from a supply voltage of 2.7V to 3.6V and over an industrial temperature range of -40°C to +85°C. The device includes an internal oscillator and a brown-out detect/reset circuit for reliable operation.
