184PIN DDR266 Unbuffered DIMM

512MB With 32Mx8 CL2.5

Description

The TS64MLD72V6F5 is a 64M x 72bits Double

Data Rate SDRAM high-density for DDR266. The

TS64MLD72V6F5 consists of 18pcs CMOS 32Mx8 bits

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

packages and a 2048 bits serial EEPROM on a 184-pin

printed circuit board. The TS64MLD72V6F5 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.

Features

• Power supply: VDD: 2.5V ± 0.2V, VDDQ: 2.5V ± 0.2V

• Max clock Freq: 133MHZ.

• Double-data-rate architecture; two data transfers per

clock cycle

• Differential clock inputs(CK and /CK)

• DLL aligns DQ and DQS transition with CK transition

• Auto and Self Refresh 7.8us refresh interval.

• 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.

• MRS cycle with address key programs.

CAS Latency (Access from column address) : 2.5
