| MITSUBISHI LSIs M5M51008CP,FP,VP,RV,KV,KR -55HI, -70HI, -55XI, -70XI 1048576-BIT(131072-WORD BY 8-BIT)CMOS STATIC RAM DESCRIPTION The M5M51008CP,FP,VP,RV,KV,KR are a 1048576-bit CMOS static RAM organized as 131072 word by 8-bit which are fabricated using high-performance quadruple-polysilicon and double metal CMOS technology. The use of thin film transistor (TFT) load cells and CMOS periphery result in a high density and low power static RAM. They are low standby current and low operation current and ideal for the battery back-up application. The M5M51008CVP,RV,KV,KR are packaged in a 32-pin thin small outline package which is a high reliability and high density surface mount device(SMD). Two types of devices are available. M5M51008CVP,KV(normal lead bend type package), M5M51008CRV,KR(reverse lead bend type package).Using both types of devices, it becomes very easy to design a printed circuit board.

Each mode is summarized in the function table. A write cycle is executed whenever the low level W overlaps with the low level S1 and the high level S2. The address must be set up before the write cycle and must be stable during the entire cycle. The data is latched into a cell on the trailing edge of W,S1 or S2, whichever occurs first,requiring the set-up and hold time relative to these edge to be maintained. The output enable input OE directly controls the output stage. Setting the OE at a high level, the output stage is in a high-impedance state, and the data bus contention problem in the write cycle is eliminated. A read cycle is executed by setting W at a high level and OE at a low level while S1 and S2 are in an active state(S1=L,S2=H). When setting S1 at a high level or S2 at a low level, the chip are in a non-selectable mode in which both reading and writing are disabled. In this mode, the output stage is in a high- impedance state, allowing OR-tie with other chips and memory expansion by S1 and S2. The power supply current is reduced as low as the stand-by current which is specified as ICC3 or ICC4, and the memory data can be held at +2V power supply, enabling battery back-up operation during power failure or power-down operation in the nonselected mode.
