C8051F02x Analog-Intensive MCUs

The C8051F02x family devices are highly integrated mixed-signal MCUs featuring two separate high speed ADC sub-systems (either 10/12-bit, 100 ksps and 8-bit, 500 ksps). These devices also include two separate 12-bit DACs.

With on-chip VDD monitor, Watchdog Timer and clock oscillator, the C8051F020/1/2/3 devices are truly stand-alone System-on-a-Chip solutions. All analog and digital peripherals are enabled/disabled and configured by user firmware. The FLASH memory can be reprogrammed even in-circuit, providing non-volatile data storage, and also allowing field upgrades of the 8051 firmware.
