HSD32M32M4V
Synchronous DRAM Module 128Mbyte ( 32M x 32-Bit ) 72-Pin SIMM based on
32Mx8, 4Banks, 8K Ref., 3.3V
Part No. HSD32M32M4V
GENERAL DESCRIPTION
The HSD32M32M4V is a 32M x 32 bit Synchronous Dynamic RAM high density memory module. The module consists
of four CMOS 8M x 8 bit with 4banks Synchronous DRAMs in TSOP-II packages mounted on a 72-pin, FR-4-printed circuit
board. Two 0.01uF decoupling capacitor is mounted on the printed circuit board in parallel for each SDRAM. The
HSD32M32M4V is a SIMM designed. 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.
