W9751G6IB-25 +BOM

ROHS compliant WBGA-84 memory component

W9751G6IB-25 Allgemeine Beschreibung

With cutting-edge technology and a state-of-the-art design, the W9751G6IB-25 redefines memory performance with its 512MB capacity and lightning-fast 400MHz speed rating. The module's 64Mx8 configuration optimizes data processing efficiency, supported by a low 1.8V voltage for enhanced energy savings. Its 8 banks of 8Mx8 bits ensure seamless operation across various computing and networking applications, while the programmable CAS latency and refresh cycle time of 15.6μs guarantee smooth performance. Featuring a Serial Presence Detect EEPROM, the module effortlessly communicates vital information to the system BIOS, enabling optimal memory settings and system compatibility. Additionally, its RoHS compliance and wide temperature range of 0°C to 85°C make it a reliable choice for diverse operating environments
