RENESAS LSIs M5M5256DFP,VP -70G,-70GI,-70XG 262144-BIT (32768-WORD BY 8-BIT) CMOS STATIC RAM DESCRIPTION The M5M5256DFP,VP is 262,144-bit CMOS static RAMs organized as 32,768-words by 8-bits which is f abricated using high-perf ormance 3 poly silicon CMOS technology . The use of resistiv e load NMOS cells and CMOS periphery results in a high density and low power static RAM. Stand-by current is small enough f or battery back-up application. It is ideal f or the memory sy stems which require simple interf ace. Especially the M5M5256DVP are packaged in a 28-pin thin small outline package.

Each mode is summarized in the f unction table. A write cy cle is executed whenev er the low lev el /W ov erlaps with the low lev el /S. The address must be set up bef ore the write cy cle and must be stable during the entire cy cle. The data is latched into a cell on the trailing edge of /W, /S, whichev er occurs f irst, requiring the setup and hold time relativ e to these edge to be maintained. The output enable /OE directly controls the output stage. Setting the /OE at a high lev el,the output stage is in a high-impedance state, and the data bus contention problem in the write cy cle is eliminated. A read cy cle is executed by setting /W at a high lev el and /OE at a low lev el while /S are in an activ e state. When setting /S at a high lev el, the chip is in a nonselectable mode in which both reading and writing are disabled. In this mode, the output stage is in a highimpedance state, allowing OR-tie with other chips and memory expansion by /S. The power supply current is reduced as low as the stand-by current which is specif ied as Icc3 or Icc4, and the memory data can be held at +2V power supply , enabling battery back-up operation during power f ailure or power-down operation in the nonselected mode.
