HDD16M72D9W

DDR SDRAM Module 128Mbyte (16Mx72bit), based on 16Mx8, 4Banks

4K Ref., 184Pin-DIMM with Unbuffered ECC Part No. HDD16M72D9W

GENERAL DESCRIPTION

The HDD16M72D9W is a 64M x 72 bit Double Data Rate(DDR) Synchronous Dynamic RAM high-density memory

module. The module consists of nine CMOS 16M x 8 bit with 4banks DDR SDRAMs in 66pin TSOP-II 400mil packages and

2K EEPROM in 8-pin TSSOP package on a 184-pin glass-epoxy. Four 0.1uF decoupling capacitors are mounted on the

printed circuit board in parallel for each DDR SDRAM. The HDD16M72D9W is a DIMM(Dual in line Memory

Module) .Synchronous design allows precise cycle control with the use of system clock. Data I/O transactions are possible

on both edges of DQS. Range of operating frequencies, programmable latencies and burst lengths allows the same device

to be useful for a variety of high bandwidth, high performance memory system applications. All module components may be

powered from a single 2.5V DC power supply and all inputs and outputs are SSTL_2 compatible.
