HSD4M64B4
Synchronous DRAM Module 32Mbyte (4Mx64-Bit), SO-DIMM,
4Banks, 4K Ref., 3.3V
Part No. HSD4M64B4
GENERAL DESCRIPTION
The HSD4M64B4 is a 4M x 64 bit Synchronous Dynamic RAM high density memory module. The module consists of
four CMOS 1M x 16 bit with 4banks Synchronous DRAMs in TSOP-II 400mil packages on a 144-pin glass-epoxy substrate.
Two 0.1uF decoupling capacitors are mounted on the printed circuit board in parallel for each SDRAM. The HSD4M64B4
is a SO-DIMM(Small Outline Dual in line Memory Module) and is intended for mounting into 144-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.
