GENERAL DESCRIPTION
MSM66V84B is a serial register organized as 4,194,304 words x one bit, characterized by mediumspeed, 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.
