Description

The MSM6389C is a solid-state recorder data register in 1,048,576 words x 1 bit configuration.

The MSM6389C has a built-in internal address generator circuit allowing continuous serial read/ write operation by si-ngle 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 of MSM6389C have eliminated the need of an external refresh circuit and realized a low power consumption.

18-pin plastic QFJ of MSM6389C is used as the package and the operating temperature range is between 0°C and 70°C.

The MSM6389C 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.
