71V2556SA100BGG

Memory IC Overview

The 71V2556SA100BGG is a 4.5 Mbit (128K x 36) synchronous ZBT SRAM manufactured by Renesas Electronics Corporation. It operates with a 3.3V core supply and supports a maximum clock frequency of 100 MHz, achieving a typical access time of 5 ns. The device utilizes a 119-pin PBGA package measuring 14x22 mm. It features pipelined architecture for high-speed data transfer and includes boundary scan capabilities via JTAG.

Memory IC Feature Summary

• Zero Bus Turnaround (ZBT) technology eliminates dead cycles during bus turnaround between read and write operations.
• Pipelined architecture allows four-word burst capability for interleaved or linear access patterns.
• Internally synchronized output buffer enable removes the need for external OE control signals.

Memory IC Applications

• High-performance real-time engine processing in industrial equipment
• Data buffering in telecommunications systems requiring low-latency memory access
• Embedded storage in automotive electronic control units

Memory IC Procurement Notes

Verify component authenticity through authorized channels due to End-of-Life status. Confirm RoHS compliance requirements as the part may not meet current environmental standards. Validate package integrity upon receipt to ensure solder joint reliability for surface mount assembly processes.

Memory IC Selection Notes

Select this component for applications requiring parallel interface synchronization without bus turnaround delays. Ensure system design accommodates the 119-pin BGA footprint and 3.3V power domain. Consider thermal management strategies suitable for the specified operating temperature range during continuous high-frequency operation.

Memory IC Part Context

This SRAM belongs to the 71V2556 family of Zero Bus Turnaround devices. It shares architectural similarities with other members like the 71V2556SA100BGI but differs in specific packaging configurations. The series is designed to replace asynchronous SRAMs in high-speed digital signal processing environments.

Memory IC Replacement Considerations

Public confirmed substitute part numbers are not available. The product has reached End-of-Life status. Designers should evaluate alternative synchronous SRAM families from the manufacturer that offer compatible pinouts and performance specifications.
