HSD32M64F8V/VA
Synchronous DRAM Module, 256Mbyte ( 32M x 64-Bit ) SMM based
on 32Mx8, 4Banks, 8K Ref., 3.3V
Part No. HSD32M64F8V/VA
GENERAL DESCRIPTION
The HSD32M64F8V/VA is a 32M x 64 bit Synchronous Dynamic RAM high density memory module. The module
consists of eight CMOS 8M x 8 bit with 4banks Synchronous DRAMs in TSOP-II packages is mounted on a 120-pin,
double-sided, FR-4-printed circuit board., Two 0.1uF decoupling capacitors are mounted on the printed circuit board in
parallel for each SDRAM. The HSD32M64F8V/VA is a SMM (Stackable Memory Module) designed and is intended for
mounting into two 60-pin 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.
