C8051F312-GQ Description

Short technical summary and product information.

The C8051F312-GQ is a high-performance 8-bit microcontroller from Silicon Labs based on the pipelined 8051 core. It operates at up to 25 MHz, delivering 25 MIPS throughput. The device includes 8KB of in-system programmable Flash memory and 1280 bytes of internal RAM. Analog peripherals include a 10-bit ADC with 21 external channels and a sampling rate of 200 ksps, along with a built-in temperature sensor and comparators. Digital peripherals provide 29 general-purpose I/O pins, hardware UART, SMBus (I²C), and SPI interfaces, plus a programmable counter array with 5 PWM channels and 4 timers. The microcontroller operates from 2.7V to 3.6V and features an internal oscillator (24.5 MHz) with ±2% accuracy. It is offered in a 32-pin LQFP package (7x7 mm) for surface-mount assembly. With on-chip debug circuitry and wide industrial temperature range (-40°C to +85°C), it is suitable for a variety of embedded control applications requiring low power and analog integration.
