C8051F342-GQ

The C8051F342-GQ is an 8-bit microcontroller from Silicon Laboratories based on the high-speed 8051 core. It operates at a maximum clock frequency of 48 MHz and includes 64KB of Flash program memory and 4.25KB of RAM. The device integrates a USB 2.0 function controller supporting full-speed (12 Mbps) and low-speed (1.5 Mbps) operation with an integrated clock recovery circuit, eliminating the need for an external crystal.

Analog peripherals include a 10-bit ADC with a sampling rate of up to 200 ksps, a built-in temperature sensor, and two comparators. Digital peripherals include SMBus/I²C, SPI, and UART/USART serial interfaces, a 16-bit programmable counter array (PCA) with five capture/compare modules, and four general-purpose 16-bit counter/timers. The microcontroller also features a brown-out detector, power-on reset (POR), and a watchdog timer (WDT).

The device operates from a 2.7V to 3.6V supply and over a temperature range of -40°C to 85°C. It is available in a 32-LQFP (7x7 mm) surface-mount package with 25 general-purpose I/O pins. On-chip debug circuitry enables non-intrusive, full-speed in-system debugging without an emulator.
