PIN CONFIGURATION (TOP VIEW)
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 x 16-bit and 4,194,304-word x 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
Package material Lead frame material Pin treatment Package weight (g) Rev. No./Last Revised
Epoxy resin 42 alloy Solder plating (5m) 0.55 TYP. 1/Dec. 2, 1999
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).
