C8051F850-C-GU

The C8051F850-C-GU is a highly integrated mixed-signal 8-bit Flash Microcontroller featuring a powerful 8051 core with 25MHz performance. The MCU offers 8kB flash, 0.5kB RAM along with I²C, SPI, UART communication interfaces and 4 x 16-bit timers. On-chip analog features include a 12-bit 15-channel 200ksps ADC and 2 comparators. With on-chip power-on reset, VDD monitor, watchdog timer, a ±2% internal oscillator. The device is truly standalone system-on-a-chip solutions. The flash memory is reprogrammable in circuit, providing non-volatile data storage and allowing field upgrades of the firmware.
