MSM6685
8,388,608-Word x 1-Bit Serial Register
This version: JManS.M19696885
Previous version: May. 1997
GENERAL DESCRIPTION
The MSM6685 is a serial register composed of 8,388,608 words x one bit, characterized by medium-
speed, low power consumption operation.
This device has a built-in internal address generation circuit allowing continuous serial read/write
operationbyexternalclockinput. Read/writeoperationcausestheinternaladdresstobeincremented
automatically by +1.
External address input enables addressing in units of 1024 words. Furthermore, a refresh timer and
a refresh address counter are installed, which makes an external refresh circuit unnecessary. In
addition, this configuration allows lower power consumption.
The device is packaged in 26-pin SOJ having a width of 300 mil.
It is well adapted for storing much data by means of a battery backup. Its combination with OKI's
recording and playback IC enables the easy implementation of a solid recording and playback
system.
