HYS72T64900 - (HYSxxTxxxxx0) 240-Pin Unbuffered DDR2 SDRAM Modules

Download the HYS72T64900 datasheet PDF. This datasheet also covers the HYS64T128920 variant, as both devices belong to the same (hysxxtxxxxx0) 240-pin unbuffered ddr2 sdram modules family and are provided as variant models within a single manufacturer datasheet.

General Description

The memory array is designed with 512-Mbit Double-DataRate-Two (DDR2) Synchronous DRAMs.

Decoupling capacitors are mounted on the PCB board.

The DIMMs feature serial presence detect based on a serial E2PROM device using the 2-pin I2C protocol.

Key Features

  • Auto Refresh (CBR) and Self Refresh Programmable self refresh rate via EMRS2 setting Programmable partial array refresh via EMRS2 settings DCC enabling via EMRS2 setting All inputs and outputs SSTL_1.8 compatible Off-Chip Driver Impedance Adjustment (OCD) and On-Die Termination (ODT) Serial Presence Detect with E2PROM UDIMM Dimensions (nominal): 30 mm high and 133.35 mm wide Based on standard refe.
