M5M5V408BFP Datasheet PDF – 4-Mbit static RAM

Part Number : M5M5V408BFP

Function : 4194304-BIT (524288-WORD BY 8-BIT) CMOS STATIC RAM

Package : 32 Pin SOP, TSOP, STSOP

Manufacturers : Mitsubishi Electric Semiconductor




Description :

The M5M5V408BFP  is a family of low voltage 4-Mbit static RAMs organized as 524,288-words by 8-bit, fabricated by Mitsubishi’s 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.
