Product Summary

The C8051F340-GQR is a Full Speed USB Flash MCU fully integrated mixed-signal System-on-a-Chip MCUs. With on-chip Power-On Reset, VDD monitor, Voltage Regulator, Watchdog Timer, and clock oscillator, the C8051F340-GQR is truly stand-alone System-on-a-Chip solutions. The Flash memory can be reprogrammed in-circuit, providing non-volatile data storage, and also allowing field upgrades of the 8051 firmware. User software has complete control of all peripherals, and may individually shut down any or all peripherals for power savings.
