Description

The Hitachi HM62V16256C Series is 4-Mbit static RAM organized 262,144-word × 16-bit. HM62V16256C

Series has realized higher density, higher performance and low power consumption by employing CMOS

process technology (6-transistor memory cell). It offers low power standby power dissipation; therefore, it is

suitable for battery backup systems. It is packaged in standard 44-pin plastic TSOPII.

Features

• Single 2.5 V and 3.0 V supply: 2.2 V to 3.6 V

• Fast access time: 55 ns/70 ns (max)

• Power dissipation:

 Active: 5.0 mW/MHz (typ)(VCC = 2.5 V)

: 6.0 mW/MHz (typ) (VCC = 3.0 V)

 Standby: 2 µW (typ) (VCC = 2.5 V)

: 2.4 µW (typ) (VCC = 3.0 V)

• Completely static memory.

 No clock or timing strobe required

• Equal access and cycle times

• Common data input and output.

 Three state output

• Battery backup operation.

 2 chip selection for battery backup
