The C8051F344-GQ is an 8-bit microcontroller based on the high-speed 8051 core from Silicon Labs. It delivers up to 48 MIPS performance with a pipelined architecture that executes 70% of instructions in 1 or 2 system clocks. The device features 64KB of in-system programmable Flash memory and 4.25K x 8 RAM. It includes a USB 2.0 compliant function controller supporting full speed (12 Mbps) and low speed (1.5 Mbps) operation with integrated clock recovery, eliminating the need for an external crystal.
On-chip analog peripherals include a 10-bit ADC with up to 200 ksps sampling rate, a built-in temperature sensor, two comparators, and an internal voltage reference. Digital peripherals include four 16-bit timers, a 16-bit programmable counter array (PCA) with five capture/compare modules, and a brown-out detect/reset circuit, power-on reset (POR), and watchdog timer (WDT). The internal oscillator provides ±0.25% accuracy with clock recovery enabled.
Connectivity options include EBI/EMI, SMBus (I²C), SPI, UART/USART, and USB. The device offers 40 general-purpose I/O pins, all 5V tolerant with high sink current. The operating voltage range is 2.7V to 3.6V, and the device is available in a 48-TQFP (7x7 mm) surface-mount package. Operating temperature range is -40°C to 85°C.
