The C8051F347-GQ is an 8-bit microcontroller from Silicon Labs based on the high-speed 8051 core. It operates at up to 25MHz and includes 32KB of Flash program memory and 2.25KB of on-chip SRAM. The device features a full-speed USB 2.0 controller with integrated transceiver and clock recovery, supporting both full-speed (12 Mbps) and low-speed (1.5 Mbps) operation without requiring an external crystal.
Analog peripherals include a 10-bit successive-approximation ADC with up to 200 ksps sample rate, built-in analog multiplexer with 21 single-ended or differential inputs, internal voltage reference, and temperature sensor. Additionally, two comparators and a brown-out detect/reset circuit are integrated.
Digital interfaces include SMBus (I²C), SPI, and a UART/USART serial port. The microcontroller provides 25 general-purpose I/O pins, all 5V tolerant with high sink current. On-chip debug circuitry enables full-speed, non-intrusive in-system debugging without an emulator.
The device is supplied in a 32-LQFP package (7x7mm) with surface-mount mounting. Operating voltage range is 2.7V to 3.6V and temperature range is -40°C to +85°C. Internal oscillator accuracy is ±0.25% with clock recovery enabled, supporting all USB and UART modes.
