71V2556SA100BGI8

Overview

The 71V2556SA100BGI8 is a 4.5 Mbit (128K x 36) synchronous ZBT SRAM in a 119-pin PBGA package. It operates with a 3.3V core supply and 2.5V I/O, supporting clock frequencies up to 166 MHz with a 3.5 ns access time. The device features pipelined architecture for high-speed data transfer.

Feature Summary

• Zero Bus Turnaround (ZBT) technology eliminates dead cycles between read and write operations.
• Pipelined architecture allows four-word burst capability for efficient data throughput.
• Internally synchronized output buffer enable removes the need for external OE control.

Applications

• High-performance real-time engine systems
• Industrial equipment requiring fast memory access
• Network infrastructure components

Procurement Notes

Verify component authenticity through authorized channels as this part is obsolete. Check RoHS compliance status carefully since it may not meet current environmental standards. Confirm package integrity upon receipt due to potential long-term storage effects on solderability.

Selection Notes

Select this component when zero bus turnaround latency is critical for system performance. Ensure design supports 3.3V core and 2.5V I/O voltage levels. Consider the 119-pin BGA footprint constraints during PCB layout planning.
