SUMMARY DESCRIPTION
The M58WR032FT/B is a 32 Mbit (2 Mbit 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 1.7V 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.
FEATURES SUMMARY
◾ SUPPLY VOLTAGE
– VDD = 1.7V to 2V for Program, Erase and
Read
