GENERAL DESCRIPTION

The MR27V802F is a 8Mbit electrically One Time Programmable Read-Only Memory that can be electrically
switched between 524,288-word

× 16-bit and 1,048,576-word × 8-bit by the state of the BYTE# pin. The

MR27V802F 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).
