HM62V16256C Series
4 M SRAM (256-kword × 16-bit)
ADE-203-1099D (Z)
Rev. 1.0
Jan. 31, 2001
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
