MSM63V89C
1,048,576-Word x 1-Bit Solid-State Recorder Data Register
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.
