C8051F332-GMR

The C8051F332-GMR is a mixed-signal ISP Flash microcontroller from Silicon Laboratories, based on the high-speed 8051 core. It operates at up to 25 MHz, delivering 25 MIPS throughput. The device includes 4 KB of in-system programmable Flash memory and 768 bytes of internal data RAM. It features 17 general-purpose I/O pins, all 5V tolerant with high sink current. Connectivity options include SMBus (I2C), SPI, and UART/USART serial interfaces. On-chip peripherals include a 10-bit ADC (up to 200 ksps, 16 channels), a comparator, programmable counter array, and four 16-bit timers. The microcontroller also integrates a temperature sensor, POR, PWM, and watchdog timer. It operates from 2.7V to 3.6V supply voltage and draws typically 6.4 mA at 25 MHz or 9 µA at 32 kHz. The stop mode current is only 0.1 µA. The device is available in a 20-VFQFN exposed pad package (20-QFN 4x4 mm) and is specified for -40°C to +85°C operation. It is suitable for embedded control applications requiring analog integration and low power consumption.
