Oki Electric Industry MSM6389C
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 single external clock input. The internal address is automatically incremented by one by read/write operation.GENERAL DESCRIPTION
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. 18-pin plastic QFJ 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.FEATURES
