Technical Specifications

The HY57V56420T-P SDRAM operates with clock frequency dependent on the speed grade. It is packaged in a TSOP. The device supports burst read and write operations. It operates with a 3.3V power supply and is LVTTL compatible. The self-refresh mode allows for low power operation when the memory is not being actively accessed.

The SDRAM's internal bank architecture enables concurrent memory accesses. An integrated DLL (Delay-Locked Loop) ensures precise timing, essential for stable and reliable operation. The HY57V56420T-P offers a balance of speed, density, and power efficiency.
