The C8051F389-B-GQ is an 8-bit microcontroller from Silicon Labs based on the high-speed 8051 core. It operates at up to 48 MIPS and features 64KB of in-system programmable Flash memory and 4.25KB of RAM. The device includes 25 general-purpose I/O pins, all 5V tolerant, and supports I²C, SPI, and UART/USART serial interfaces.
On-chip peripherals include a 10-bit ADC with 21 channels and up to 500 ksps sampling rate, two comparators, a temperature sensor, brown-out detection, power-on reset, PWM, and a watchdog timer. The internal oscillator provides ±1.5% accuracy, and a low-frequency 80 kHz oscillator is also available.
The device operates from 2.7V to 5.25V over a temperature range of -40°C to 85°C and is available in a 32-LQFP (7x7 mm) surface-mount package. It includes on-chip debug circuitry for non-intrusive in-system debugging.
