SUMMARY DESCRIPTION

The M58WR064FT/B is a 64 Mbit (4Mbit x16) nonvolatile Flash memory that may be erased electrically at block level and programmed in-system on a Word-by-Word basis using a 1.7V to 2V VDD supply for the circuitry and a 1.7V to 2.24V 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.
