SUMMARY DESCRIPTION
The M58CR032 is a 32 Mbit (2Mbit 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 2.0V 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. The VPP pin can also be used as a control pin to provide absolute protection against program or erase.
