MSM63V89C
1,048,576-Word x 1-Bit Solid-State Recorder Data Register
GENERAL DESCRIPTION
The MSM63V89C is a solid-state recorder data register in 1,048,576 words x 1 bit configuration.
The MSM63V89C 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.
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.
26/20-pin plastic TSOP is used as the package and the operating temperature range is between 0°C
and 70°C.
The MSM63V89C 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
• Configuration: 1,048,576 x 1 bit
• Serial access operation:
Serial access time 1.5 ms (3.0 ms)
Serial read/write cycle time 2.0 ms (4.0 ms)
Fast mode read/write cycle time 0.4 ms (0.4 ms)
Times in parentheses indicate ones in self-refresh mode.
• Low current consumption: 50 mA max. (for data holding, VCC=3.0 V)
• Wide operating supply voltage range: Single 2.7 to 3.6V
• Auto-refresh/self-refresh changeable
• Package:
26/20-pin plastic TSOP (TSOPII26/20-P-300-1.27-K) (Product name: MSM63V89CTS-K)
