Product Summary

The C8051F326-GMR is a Full Speed USB. With on-chip power-on reset, VDD monitor, voltage regulator, and clock oscillator, The C8051F326-GMR 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. The C8051F326-GMR is available in two 28-pin QFN packages with different pinouts. The RoHS compliant devices are marked with a -GQ suffix in the part number. The port I/O on C8051F326-GMR is powered from a separate I/O supply allowing it to interface to low voltage logic.
