Previous version: May. 1997

GENERAL DESCRIPTION

MSM66V84B is a serial register organized as 4,194,304 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

operation by external clock input.

Read/write operation causes the internal address to be incremented 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 26/20-pin SOJ or 26/20 TSOP having a width of 300 mil.

It is well adapted for storing much data by means of a battery backup. Its combination with our

recording and playback LSI enables the easy implementation of a solid recording and playback

system.
