GENERAL DESCRIPTION
The MR27V1602F is a 16 Mbit electrically One Time Programmable Read-Only Memory that can be
electrically switched between 1,048,576-word
×
16-bit and 2,097,152-word
×
8-bit by the state of the BYTE# pin.
The MR27V1602F supports high speed asynchronous read operation using a single 3.3V power supply.
