MR27V1652F
P2ROM1M–Word × 16–Bit or 2M–Word × 8–Bit Page Mode
FEDR27V1652F-02-02
Issue Date: Jul. 9, 2004
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.
