C8051F320-GQ Description

Short technical summary and product information.

The C8051F320-GQ is an 8-bit microcontroller from Silicon Labs based on the high-speed 8051 core. It operates at up to 25 MHz, delivering 25 MIPS throughput. The device integrates 16 KB of in-system programmable Flash memory and 2.25 KB of RAM (including 1 KB USB FIFO).

Connectivity includes a USB 2.0 controller supporting full-speed (12 Mbps) and low-speed (1.5 Mbps) operation with integrated clock recovery, eliminating the need for an external crystal. Additional serial interfaces include SMBus/I2C, SPI, and UART/USART. The microcontroller features a 10-bit ADC with up to 200 ksps sampling rate and 17 external single-ended or differential inputs, along with two comparators, a temperature sensor, and brown-out detection.

The device operates from a 2.7V to 3.6V supply and includes an internal voltage regulator that can accept 4.0V to 5.25V for USB bus-powered applications. It is specified for industrial temperature range (-40°C to +85°C) and is available in a 32-pin LQFP (7x7 mm) surface mount package. The internal oscillator is accurate to 0.25% with clock recovery enabled.
