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.
