MSM63V89C

1/10

GENERAL DESCRIPTION

The MSM63V89C is a solid-state recorder data register in 1,048,576 words x 1 bit configuration.

The MSM63V89C has a built-in internal address generator circuit allowing continuous serial read/

write operation by single external clock input. The internal address is automatically incremented by

one by read/write operation.

Address designation in units of 1024 words in the direction of words is possible by an external

serial address input.

The built-in refresh timer and refresh counter have eliminated the need of an external refresh circuit

and realized a low power consumption.

26/20-pin plastic TSOP is used as the package and the operating temperature range is between 0

°C

and 70

°C.

The MSM63V89C is suitable for storing large capacity data with battery backup. A solid state

recording and playback system can easily be constructed in combination with OKI’s voice synthesizer

ICs.
