SUMMARY DESCRIPTION

The M58CR064 is a 64 Mbit (4Mbit x16) non-volatile Flash memory that may be erased electrically at block level and programmed in-system on a Word-by-Word basis using a 1.65V to 2V VDD supply for the circuitry and a 1.65V to 3.3V VDDQ supply for the Input/Output pins. An optional 12V VPP power supply is provided to speed up customer programming. In M58CR064C and M58CR064D the VPP pin can also be used as a control pin to provide absolute protection against program or erase. In M58CR064P and M58CR064Q this feature is disabled.
