The C8051F389-GQ is an 8-bit microcontroller based on the high-performance 8051 core, capable of executing up to 48 MIPS. It integrates 64KB of Flash program memory, 4.25KB of RAM, and a full-speed USB 2.0 controller supporting both 12 Mbps and 1.5 Mbps operation. The device includes a 10-bit ADC with a sampling rate of up to 500 ksps, a built-in temperature sensor, and multiple serial interfaces: I2C, SPI, and UART/USART.
Key peripherals include brown-out detect, power-on reset (POR), PWM outputs, and a watchdog timer (WDT). The internal oscillator provides ±0.25% accuracy with clock recovery, eliminating the need for an external crystal in many applications. Operating from a supply voltage range of 2.7V to 5.25V, the MCU is suited for both 3.3V and 5V systems.
The C8051F389-GQ is housed in a 32-pin LQFP package with 25 general-purpose I/O pins, all 5V tolerant with high sink current. It operates over the industrial temperature range of -40°C to +85°C, making it appropriate for embedded control, USB peripherals, and mixed-signal applications.
