GENERAL DESCRIPTION

The HDD16M64F8 is a 32M x 64 bit Double Data Rate(DDR) Synchronous Dynamic RAM high-density memory module.

The module consists of eight CMOS 16M x 8 bit with 4banks DDR SDRAMs in 66pin TSOP-II 400mil packages and 2K

EEPROM in 8-pin TSSOP package on a 200-pin glass-epoxy. Four 0.1uF decoupling capacitors are mounted on the printed

circuit board in parallel for each DDR SDRAM. The HSD16M64F8L is a SMM(Stackable Memory Module

type) .Synchronous design allows precise cycle control with the use of system clock. Data I/O transactions are possible on

both edges of DQS. Range of operating frequencies, programmable latencies and burst lengths 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 2.5V DC power supply and all inputs and outputs are SSTL_2 compatible.
