HSD64M64F8K
Synchronous DRAM Module 512Mbyte (64Mx64bit), SMM, based on
32Mx8, 4Banks, 4K Ref., 3.3V
Part No. HSD64M64F8K
GENERAL DESCRIPTION
The HSD64M64F8K 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 and 2K EEPROM in 8-pin
TSSOP package on a 120-pin glass-epoxy. One 0.22uF and two 0.0022uF decoupling capacitors are mounted on the
printed circuit board in parallel for each SDRAM. The HSD64M64F8k 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.
