Synchronous DRAM Module 256Mbyte (32Mx64bit), SMM ,16Mx16,
4Banks, 8K Ref. 3.3V
Part No. HSD32M64F8R
GENERAL DESCRIPTION
The HSD32M64F8R is a 32M x 64 bit Synchronous Dynamic RAM high-density memory module. The module consists
of eight CMOS 16M 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. Three 0.1uF decoupling capacitors are mounted on the printed circuit board in
parallel for each SDRAM. The HSD32M64F8R 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.
