DESCRIPTION

The M5M5V408B is a family of low voltage 4-Mbit static RAMs organized as 524,288-words by 8-bit, fabricated by Mitsubishis high performance 0.25μm CMOS technology.

The M5M5V408B is suitable for memory applications where a simple interfacing , battery operating and battery backup are the important design objectives.

M5M5V408B 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, M5M5V408BTP (normal-lead-bend TSOP), M5M5V408BRT (reverse-lead-bend TSOP), M5M5V408BKV (normal-lead-bend STSOP) and M5M5V408BKR (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.
