Transcend 512MB DDR266 ECC Registered Memory TS64MDR72V6L5 User Manual

 

Description 

The TS64MDR72V6L5 is a Low Profile 64M x 72bits 

Double Data Rate SDRAM high density for PC-266. The 

TS64MDR72V6L5 consists of 18pcs CMOS 64Mx4 bits 

Double Data Rate SDRAMs in 66 pin TSOP-II 400mil 

packages, 2pcs drive ICs for input control signal, 1pcs PLL, 

and a 2048 bits serial EEPROM on a 184-pin printed circuit 

board. The TS64MDR72V6L5 is a Dual In-Line Memory 

Module and is intended for mounting into 184-pin 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 operation frequencies, 

programmable latencies allow the same device to be useful 

for a variety of high bandwidth, high performance memory 

system applications. 

 

•  Max clock Freq: 133MHZ. 
•  Burst Mode Operation. 
•  Auto and Self Refresh. 

• 

All inputs except data & DM are sampled at the 

positive going edge of the system clock (ck).

 

• 

Data I/O transactions on both edge of data strobe.

 

• 

Edge aligned data output, center aligned data input.

 

•  Serial Presence Detect (SPD) with serial EEPROM   
•  SSTL-2 compatible inputs and outputs. 
•  Single 2.5V ± 0.2V power supply. 
•  MRS cycle with address key programs.
