HSD64M64F8KA
Synchronous DRAM Module 512Mbyte (64Mx64bit), SMM, based on
32Mx8 ,4Banks, 4K Ref., 3.3V
GENERAL DESCRIPTION
The HSD64M64F8KA is a 64M x 64 bit Synchronous Dynamic RAM high-density memory module. The module consists
of sixteen CMOS 32M x 8 bit with 4banks Synchronous DRAMs in TSOP-II 400mil packages on a 120-pin glass-epoxy.
One 0.22uF and two 0.1uF decoupling capacitors are mounted on the printed circuit board in parallel for each SDRAM.
The HSD64M64F8KA is a SMM(Stackable Memory Module type) .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.
