GENERAL DESCRIPTION
The HDD32M72D9RPW is a 32M x 72 bit Double Data Rate(DDR) Synchronous Dynamic RAM high-density memory
module. The module consists of nine CMOS 32M 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 HDD32M72D9RPW 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.
