4 M SRAM (256-kword × 16-bit)
ADE-203-976B (Z)
Rev. 2.0
Oct. 14, 1999
Description
The Hitachi HM62W16258B Series is 4-Mbit static RAM organized 262,144-word × 16-bit. HM62W16258B
Series has realized higher density, higher performance and low power consumption by employing Hi-CMOS
process technology. 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 3.3 V supply: 3.3 V ± 0.3 V
Fast access time: 55 ns/70 ns (max)
Power dissipation:
Active: 9.9 mW (typ)
Standby: 3.3 µW (typ)
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.
