The C8051F394-A-GM is a highly integrated mixed-signal 8-bit microcontroller from Silicon Labs, built around a powerful 8051 core capable of up to 50MHz operation. It offers 8KB of Flash program memory and 1KB of internal RAM, making it suitable for a wide range of embedded control applications.
On-chip analog peripherals include a 10-bit ADC with up to 500 ksps throughput and 16 external inputs, two 10-bit current-output DACs, a comparator, and a precision temperature sensor accurate to ±2°C without user calibration. Digital peripherals include 21 general-purpose I/O pins, UART, SMBus/I²C, and SPI serial interfaces, along with six 16-bit timers and a programmable counter array with PWM capability.
The device operates from 1.8V to 3.6V and over a temperature range of -40°C to +105°C. It is housed in a 24-pin QFN package measuring 4x4 mm, making it ideal for space-constrained designs. The C8051F394-A-GM is not recommended for new designs; Silicon Labs recommends the EFM8BB31F64I-4QFN24 as a replacement.
