HM628100I Series
Wide Temperature Range Version
8 M SRAM (1024-kword × 8-bit)
ADE-203-1302B (Z)
Rev. 1.0
Sep. 25, 2002
Description
The Hitachi HM628100I Series is 8-Mbit static RAM organized 1,048,576-word × 8-bit. HM628100I 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 TSOP II for high density surface mounting.
Features
• Single 5.0 V supply: 5.0 V ± 10 %
• Fast access time: 55 ns (max)
• Power dissipation:
Active: 10 mW/MHz (typ)
Standby: 7.5 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.
2 chip selection for battery backup
• Temperature range: –40 to +85°C
