Description
The Hitachi HM62V16256CI Series is 4-Mbit static RAM organized 262,144-word à 16-bit.
HM62V16256CI 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: 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
⢠Temperature range: â40 to +85°C
