Description

The TS256MDR72V6S is a 256M x 72bits Double Data Rate SDRAM high-density for DDR266. The TS256MDR72V6S consists of 36pcs CMOS 128Mx4 bits Double Data Rate SDRAMs in 60 ball FBGA packages, 2pcs drive ICs for input control signal, 1pcs PLL, and a 2048 bits serial EEPROM on a 184-pin printed circuit board. The TS256MDR72V6S 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

•         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 2.6V ± 0.1V power supply.

•         MRS cycle with address key programs.

CAS Latency (Access from column address): 2.5

Burst Length (2,4,8)
