HSD8M64D4B
Synchronous DRAM Module 64Mbyte (8Mx64-Bit), DIMM, 4Banks,
4K Ref., 3.3V
Part No. HSD8M64D4B
GENERAL DESCRIPTION
The HSD8M64D4B is a 8M x 64 bit Synchronous Dynamic RAM high density memory module. The module consists of
four CMOS 2M x 16 bit with 4banks Synchronous DRAMs in TSOP-II 400mil packages on a 168-pin glass-epoxy substrate.
Two 0.1uF decoupling capacitors are mounted on the printed circuit board in parallel for each SDRAM. The HSD8M64D4B
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.
