C8051F340 Datasheet

Full Speed USB Flash MCU Family


C8051F340 is fully integrated mixed-signal System-on-a-Chip MCUs.C8051F340 device 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.
