... SUMMARY DESCRIPTION The M28W160B Mbit (1 Mbit x 16) non-vol- atile Flash memory that can be erased electrically at the block level and programmed in-system on a Word-by-Word basis. These operations can be performed using a single low voltage (2.7 to 3.6V) supply. V allows to drive the I/O pin down to DDQ 1 ...
