C8051F330-GMR

The Silicon Labs C8051F330-GMR is an 8-bit microcontroller based on the high-performance 8051 core, operating at up to 25 MHz. It integrates 8 KB of Flash program memory and 768 bytes of internal RAM, along with 17 general-purpose I/O pins that are 5 V tolerant. The device includes a rich set of digital peripherals: SMBus (I²C), SPI, and UART serial interfaces, four 16-bit timers, a programmable counter array (PCA) with three capture/compare modules, and a watchdog timer. Analog features include a 10-bit ADC with up to 200 ksps and 16 external channels, a 10-bit current-output DAC, an internal temperature sensor, and a comparator. The MCU operates from 2.7 V to 3.6 V and features two internal oscillators: a 24.5 MHz oscillator with ±2% accuracy for crystal-less UART operation and a low-power 80/40/20/10 kHz oscillator. Typical operating current is 6.4 mA at 25 MHz and 9 µA at 32 kHz; stop mode current is just 0.1 µA. The device is housed in a 20-VFQFN Exposed Pad package (20-MLP 4x4 mm), surface mountable, and rated for -40°C to +85°C operation. This mixed-signal MCU is suitable for embedded control, sensor interface, and low-power applications.
