This version:
Jan. 2001
GENERAL DESCRIPTION
The MR27V852E is a 8 Mbit electrically One Time Programmable Read-Only Memory with page mode. Its configuration can be electrically switched between 524,288-word x 16-bit and 1,048,576-word x 8-bit by the state of the BYTE pin. The MR27V852E supports high speed asynchronous read operation using a single 3.3V power supply.

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).
