NT5TU128M8DE-3C - 1Gb DDR2 SDRAM

Download the NT5TU128M8DE-3C datasheet PDF. This datasheet also covers the NT5TU256M4GE variant, as both devices belong to the same 1gb ddr2 sdram family and are provided as variant models within a single manufacturer datasheet.

Description

The 1giga-bit (1Gb) Double-Data-Rate-2 (DDR2) DRAMs is a high-speed CMOS Double Data Rate 2 SDRAM containing 1,073,741,824 bits.

It is internally configured as an octal-bank DRAM.

The 1Gb chip is organized as 32Mbit x 4 I/O x 8 bank, 16Mbit x 8 I/O x 8 bank or 8Mbit x 16 I/O x 8 bank device.

Features

  • (1) posted CAS with additive latency, (2) write latency = read latency -1, (3) normal and weak strength data-output driver, (4) variable data-output impedance adjustment and (5) an ODT (On-Die Termination) function. All of the control and address inputs are synchronized with a pair of externally supplied differential clocks. Inputs are latched at the cross point of differential clocks (CK rising and  falling). All I/Os are synchronized with a single ended DQS or differential DQS pair in a so.
