The C8051F340-GQR is a high-performance 8-bit microcontroller from Silicon Labs based on the 8051 core architecture. It operates at up to 48 MHz and provides 64 KB of Flash program memory and 4.25 KB of RAM. The device includes a full-speed USB 2.0 controller with integrated clock recovery, eliminating the need for an external crystal.
It features 40 general-purpose I/O pins, a 10-bit ADC with 20 channels (up to 200 ksps), two comparators, and an internal voltage reference. Connectivity options include SMBus (I2C), SPI, UART/USART, and an external memory interface (EMI). On-chip peripherals include a brown-out detector, POR, PWM, temperature sensor, and watchdog timer.
The microcontroller is housed in a 48-TQFP package (7x7 mm) with surface mount mounting. It operates over a supply voltage range of 2.7 V to 5.25 V and a temperature range of -40°C to 85°C. The device is RoHS compliant and lead-free.
