Technical Specifications

The UPD45128441G5-A10 SDRAM operates with a clock frequency that allows for access times of 10ns. It is packaged in a standard TSOP package for easy board mounting. The device supports burst read and write operations, which enhances data throughput. It operates with a single 3.3V power supply and is LVTTL compatible. The self-refresh mode enables low-power operation when the memory is not being actively accessed.

The SDRAM's architecture includes internal banks that enable concurrent memory accesses, increasing overall system performance. An integrated DLL (Delay-Locked Loop) ensures precise timing, crucial for stable and reliable operation. Various test and diagnostic features are included to ensure quality and reliability. The UPD45128441G5-A10 offers a combination of speed, density, and power efficiency.
