HSD2M64B2
Synchronous DRAM Module 16Mbyte (2Mx64-Bit), SO-DIMM,
4Banks, 4K Ref., 3.3V
Part No. HSD2M64B2
GENERAL DESCRIPTION
The HSD2M64B2 is a 2M x 64 bit Synchronous Dynamic RAM high density memory module. The module consists of
two CMOS 512K x 32 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
HSD2M64B2 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.
