262,144-Word x 1-Bit Serial Register
This version: FMebS.M19695986
Previous version: May. 1997
The MSM6586 is a serial register in 262,144 words x 1 bit configuration featuring medium speed
operation with low power consumption.
The MSM6586 has a built-in internal address generator circuit allowing continuous serial read/write
www.DataShebety4Uo.nceomby 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
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 MSM6586 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.
