GENERAL DESCRIPTION
The MR27V1652F is a 16 Mbit Production Programmed Read-Only Memory (P2ROM) with page mode. Its
configuration 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 MR27V1652F supports high speed asynchronous read operation using a single 3.3V
power supply.
