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.

Notes for Mounting the Surface Mount Type Package
The surface mount type packages are very susceptible to heat in reflow mounting and humidity
absorbed in storage.
Therefore, before you perform reflow mounting, contact Oki's responsible sales person for the product
name, package name, pin number, package code and desired mounting conditions (reflow method,
temperature and times).
