General Description

The ADATA’s ADQYE1B16 is a 256Mx64 bits 2GB(2048MB) DDR2-1066(CL5) SDRAM EPP memory module,

The SPD is programmed to JEDEC standard latency 800Mbps timing of 5-5-5-18 at 1.8V. The module is composed

of sixteen 128Mx8 bits CMOS DDR2 SDRAMs in FBGA package and one 2Kbit EEPROM in 8pin TSSOP (TSOP)

package on a 240pin glass–epoxy printed circuit board.

The ADQYE1B16 is a Dual In-line Memory Module and intended for mounting onto 240-pins edge connector

sockets. 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 allow

the same device to be useful for a variety of high bandwidth, high performance memory system applications.
