revision-K0.1e, ' 98.07.30 MITSUBISHI LSIs M5M5408BFP/TP/RT/KV/KR PRELIMINARY Notice: This is not a final specification. Some parametric limits are subject to change 4194304-BIT (524288-WORD BY 8-BIT) CMOS STATIC RAM DESCRIPTION The M5M5408B is a family of 4-Mbit static RAMs organized as 524,288-words by 8-bit, fabricated by Mitsubishi's highperformance 0.25µm CMOS technology. The M5M5408B is suitable for memory applications where a simple interfacing , battery operating and battery backup are the important design objectives. M5M5408B is packaged in 32-pin plastic SOP, 32-pin plastic TSOP and 32-pin 8mm x 13.4mm STSOP packages. Two types of TSOPs and two types of STSOPs are available , M5M5408BTP (normal-lead-bend TSOP) , M5M5408BRT (reverse-lead-bend TSOP) , M5M5408BKV (normal-lead-bend STSOP) and M5M5408BKR (reverse-lead-bend STSOP). These two types TSOPs and two types STSOPs are suitable for a surface mounting on double-sided printed circuit boards. From the point of operating temperature, the family is divided into three versions; "Standard", " W-version", and "I-version". Those are summarized in the part name table below. FEATURES Single +5V power supply Small stand-by current: 0.4µA(3V,typ.) No clocks, No refresh Data retention supply voltage=2.0V to 5.5V All inputs and outputs are TTL compatible. Easy memory expansion by S Common Data I/O Three-state outputs: OR-tie capability OE prevents data contention in the I/O bus Process technology: 0.25...
