DTM65525B

2 GB, 240-Pin DDR2 FB-DIMM

Features Description

240-pin JEDEC-compliant DIMM, 133.35 mm wide by

30.35 mm high

Data Transfer Rate: 6.4 Gigabytes/sec

Operating Voltage: VDD = 1.8 V ±0.1; VCC = 1.5V ±0.1

SMBus interface to AMB for configuration register

access

MBIST and IBIST test functions

Transparent mode for DDR2 SDRAM test support

Full DIMM Heat Spreader

High-speed differential point-to-point link

Fully RoHS Compliant

The DTM65525B is a Dual Rank PC2-6400 Fully Buffered

256MX72 ECC DIMM that conforms to the JEDEC FB-DIMM

standard. Each rank is comprised of nine Hynix 128Mx8

DDR2 DRAMs. One IDT (Rev C1) Advanced Memory Buffer

(AMB) is used as the interface between the system memory

bus and DIMM DRAMs. One 2K-bit EEPROM is used for

Serial Presence Detect. For improved thermal performance,

a Full DIMM Heat Spreader with thermal interface material

(TIM) is attached to the front and back of the DIMM.
