ESA2UN321(1/4)-(60/70)(J/T)(G/S)-S
8MByte (2M x 32) CMOS EDO DRAM Module
General Description
The ESA2UN321(1/4)-(60/70)(J/T)(G/S)-S is a high performance, EDO (Extended Data Out) 8-megabyte dynamic RAM module
organized as 2M words by 32bits, in a 72-pin, leadless, single-in-line memory module (SIMM) package. ESA2UN3211 supports
2K refresh. ESA2UN3214 supports 4K refresh.
The module utilizes four, Fujitsu MB811(8/6)1605A-(60/70)PJ CMOS 1Mx16 EDO dynamic RAM in a surface mount package on
an epoxy laminate substrate. Each device is accompanied by a decoupling capacitor for improved noise immunity.
Control lines provided are such that byte control is possible.
Features
• High Density: 8MByte
• Fast Access Time of 60/70 ns (max.)
• Low Power:
Active (60/70 ns)
1.8/1.7 W (max.) - 1K
1.3/1.2 W (max.) - 4K
44mW (max.) - Standby (TTL)
22mW (max.) - Standby (CMOS)
• TTL-compatible inputs and outputs
• Separate power and ground planes
• Single power supply of 5V
±
10%
• Height: 1.000 inch (TSOP)
0.850 inch (SOJ)
