1997 GENERAL DESCRIPTION The MSM6587 is a serial register in 524,288 words x 1 bit configuration featuring medium speed operation with low-power consumption.
The MSM6587 has a built-in internal address generator circuit allowing continuous serial read/write operation by external clock input.
The internal address is automatically incremented or decremented www.

com by one by read/write operation.
Address increment or decrement can be selected by external input.
Address designation in units of 1024 words in the direction of words is possible by an external serial address input.
A refresh timer and refresh counter are built in to eliminate the need of the external refresh circuit and to realize low power consumption.
18-pin plastic QFJ (PLCC) is used as the package and the operating temperature range is between 0°C and 70°C.
The MSM6587 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.
