71V3556SA133BGGI8

Memory IC Overview

The Renesas Electronics Corporation 71V3556SA133BGGI8 is a static random-access memory (SRAM) device organized as 128K x 36, providing a total storage capacity of 4.5 Mbit. It operates with a maximum clock frequency of 133 MHz and features an access time of 4.2 ns. The component utilizes a parallel interface and requires a supply voltage between 3.135 V and 3.465 V. It supports surface mount installation in a 119-PBGA package measuring 14x22 mm. The device functions within a temperature range of -40°C to +85°C.

Memory IC Feature Summary

• Synchronous Single Data Rate Zero Bus Turnaround architecture eliminates dead cycles during bus turnaround operations.
• Pipelined output buffers provide four-word burst capability for interleaved or linear addressing modes.
• Positive clock-edge triggered registers for address, data, and control signals enable fully pipelined applications.

Memory IC Applications

• High-speed data buffering in telecommunications equipment
• Cache memory implementation in network processing systems
• FIFO buffer applications requiring zero wait states

Memory IC Procurement Notes

Verify current availability status as the product may be subject to end-of-life notices. Confirm RoHS compliance requirements against specific project standards. Ensure proper handling procedures are followed due to moisture sensitivity classification. Validate that the 119-pin PBGA footprint matches the target PCB design constraints before finalizing procurement decisions.

Memory IC Selection Notes

Select this component when zero bus turnaround performance is critical for system throughput. The 133 MHz speed grade suits high-frequency synchronous interfaces. Consider the 128K x 36 organization for wide-data path requirements. Evaluate the 119-PBGA package suitability for automated surface-mount assembly processes and thermal management needs.

Memory IC Part Context

This part belongs to the 71V3556SA series of 3.3V Synchronous ZBT SRAMs. It shares architectural similarities with other variants like the 71V3556SA166BQGI8 but differs in speed grade and package type. The series is designed to replace asynchronous SRAMs in high-performance computing environments by eliminating bus turnaround delays.

Memory IC Replacement Considerations

Public confirmed substitute part numbers include IDT71V3556SA133BGGI8. Verify pinout compatibility and electrical specifications before substitution. Check for any packaging differences that might affect board layout.
