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 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 externalserial 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) of MSM6587 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.
