PDC4UL6484H-(102/103)T-S
32MByte (4M x 64) CMOS, PC/100
Synchronous DRAM Module
General Description
The PDC4UL6484H-(102/103)T-S is a high performance, 32-megabyte synchronous, dynamic RAM module organized as 4M
words by 64 bits, in a 168-pin, dual-in-line memory module (DIMM) package.
The module utilizes sixteen Fujitsu MB81F16822D-(102/103)LFN CMOS 2Mx8 synchronous dynamic RAMs in surface mount
package (TSOP) on an epoxy laminated substrate. Each device is accompanied by a decoupling capacitor for improved noise
immunity.
A 256 Byte Serial EEPROM contains the module configuration information.
Features
• High Density
• Cycle Time:
• Low Power:
32MByte
10ns
Active 5.6W
• LVTTL-compatible inputs and outputs
• Separate power and ground planes to improve noise immunity
• Single power supply of 3.3V±0.3V
• Height: 1.250 inch
