Product Summary
The C8051F021-GQR is a mixed-Signal 8KB ISP flash MCU. With on-chip VDD monitor, Watchdog Timer, and clock oscillator, the C8051F021-GQR IS truly stand-alone System-on-a-Chip solutions. All analog and digital peripherals are enabled/disabled and configured by user firmware. The C8051F021-GQR can be reprogrammed even in-circuit, providing non-volatile data storage, and also allowing field upgrades of the 8051 firmware.
