Issue Date: Jul. 9, 2004 MR27V3252J 2M–Word × 16–Bit or 4M–Word × 8–Bit Page Mode OTP GENERAL DESCRIPTION The MR27V3252J is a 32 Mbit electrically One Time Programmable Read-Only Memory with page mode. Its configuration can be electrically switched between 2,097,152-word × 16-bit and 4,194,304-word × 8-bit by the state of the BYTE# pin. The MR27V3252J supports high speed asynchronous read operation using a single 3.3V power supply.
