The C8051F34A-GQR is an 8-bit microcontroller from Silicon Laboratories based on the high-speed 8051 core. It operates at a maximum clock speed of 48MHz and features 64KB of Flash program memory and 4.25KB of RAM. The device includes a 10-bit ADC with a sampling rate of up to 200 ksps, a built-in temperature sensor, and multiple peripherals such as Brown-out Detect/Reset, POR, PWM, and WDT.
Connectivity options include SMBus (I²C), SPI, UART/USART, and a USB 2.0 controller supporting full-speed (12 Mbps) and low-speed (1.5 Mbps) operation. The internal oscillator achieves ±0.25% accuracy with clock recovery enabled, eliminating the need for an external crystal in many applications.
The microcontroller is supplied in a 32-LQFP (7x7 mm) surface-mount package and operates over a temperature range of -40°C to 85°C. The supply voltage range is 2.7V to 3.6V. It has 25 general-purpose I/O pins that are 5V tolerant.
