HSD32M72D18P
Synchronous DRAM Module 256Mbyte (32Mx72bit), DIMM with ECC based on
16Mx8, 4Banks, 4K Ref., 3.3V Part No. HSD32M72D18P (Unbuffered)
GENERAL DESCRIPTION
The HSD32M72D18P is a 32M x 72 bit Synchronous Dynamic RAM high-density memory module. The module consists
of eighteen CMOS 16M x 8 bit with 4banks Synchronous DRAMs in TSOP-II 400mil packages and 2K EEPROM in 8-pin
TSSOP package on a 168-pin glass-epoxy. Two 0.33uF-decoupling capacitors are mounted on the printed circuit board in
parallel for each SDRAM. The HSD32M72D18P is a DIMM (Dual in line Memory Module) and is intended for mounting into
168-pin edge connector sockets. Synchronous design allows precise cycle control with the use of system clock. I/O
transactions are possible on every clock cycle. Range of operating frequencies, programmable latencies 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 3.3V DC power supply and all inputs and outputs are LVTTL-compatible.
