HSD32M64D16R
Synchronous DRAM Module 256Mbyte (32Mx64bit), DIMM with based on 16Mx8,
4Banks, 4K Ref., 3.3V
GENERAL DESCRIPTION
The HSD32M64D16R is a 32M x 64 bit Synchronous Dynamic RAM high-density memory module. The module consists
of sixteen 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. One 0.22uF and two 0.0022uF decoupling capacitors are mounted on the
printed circuit board in parallel for each SDRAM. The HSD32M72D18AR 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.
