DDR SDRAM SO-DIMM MODULE, 2.5V 1GByte - 128MX72 AVK7228U52C3400K8-AP FEATURES JEDEC Compliant DDR 400MHz Version 1.0, Lead Free, RoHS compliant Clock frequency: 200MHz with CAS latency 3 256 byte serial EEPROM Data input and output masking Programmable burst length: 2, 4, 8 Programmable burst type: sequential and interleave Programmable CAS latency: 3 Auto refresh and self refresh capability Gold card edge fingers 8K refresh per 64ms Low active and standby current consumption SSTL-2 compatible inputs and outputs Decoupling capacitors at each memory device Double-sided module 30mm (1.181 inch) height DESCRIPTION The AVK7228U52C3400K8-AP is an Unbuffered DDR SDRAM SODIMM memory module. This module is JEDEC- standard 200-pin, small-outline, dual in-line memory module. A 256 byte serial EEPROM on board can be used to store module information such as timing, configuration, density, etc. The AVK7228U52C3400K8-AP memory module is 1GByte and organized as a 128MX72 array using (18) 64MX8 DDR SDRAMs in lead free BGA packages. All memory modules are fabricated using the latest technology design, six-layer printed circuit board substrate construction with low ESR decoupling capacitors on-board for high reliability and low noise.
