GENERAL DESCRIPTION
The MR27V1602E is a 16 Mbit electrically One Time Programmable Read-Only Memory with page mode. Its
configuration can be electrically switched between 1,048,576-word × 16-bit and 2,097,152-word × 8-bit by the
state of the BYTE pin. The MR27V1652E 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).
