HSD32M64D8A
Synchronous DRAM Module 64Mbyte (8Mx72bit),DIMM based on
32Mx8, 4Banks, 8K Ref., 3.3V
Part No. HSD32M64D8A
GENERAL DESCRIPTION
The HSD32M64D8A is a 32M x 64 bit Synchronous Dynamic RAM high density memory module. The module consists
of eight
CMOS 8M x 8 bit with 4banks Synchronous DRAMs in TSOP-II 400mil packages on a 168-pin glass-epoxy
substrate. Two 0.33uF decoupling capacitors are mounted on the printed circuit board in parallel for each SDRAM. The
HSD32M64D8A 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.
