71V3577S85BGG8

Overview

The 71V3577S85BGG8 is a synchronous static random-access memory integrated circuit manufactured by Renesas Electronics. It features a storage organization of 128K x 36 bits, providing a total capacity of 4.5 Mbit. The device supports a maximum clock frequency of 87 MHz with an access time of 8.5 ns. It operates on a single 3.3V power supply within a voltage range of 3.135V to 3.465V. The component utilizes a parallel interface and is housed in a 119-pin plastic ball grid array (PBGA) package measuring 14x22 mm.

Feature Summary

• Supports synchronous Single Data Rate (SDR) operation for high-speed data transfer
• Provides flow-through output architecture for continuous data availability
• Includes self-timed write cycles with global write control and byte write enable capabilities

Applications

• High-performance computing systems requiring fast buffer memory
• Network infrastructure equipment utilizing synchronous SRAM
• Industrial control systems needing reliable volatile data storage

Procurement Notes

Verify the specific suffix BGG8 against official Renesas documentation to confirm package type and temperature grade. Confirm current lifecycle status as this series has faced end-of-life notifications. Ensure compatibility with existing PCB footprints for the 119-PBGA format before procurement.

Selection Notes

Select this component when a 128K x 36 organization is required with 8.5 ns access speed. Compare against the 71V3577S75 variant if faster 7.5 ns performance is needed. Verify that the 3.3V I/O levels match the system logic requirements and that the PBGA package fits the assembly constraints.

Part Context

This part belongs to the 71V3577 family of 3.3V synchronous SRAMs. The family offers various access speeds and packaging options including TQFP and fpBGA. The 71V3577S85 specifically denotes the 8.5 ns speed grade within the SDR technology line, distinct from ZBT variants found in other model numbers.

Replacement Considerations

Check for direct substitutes within the 71V3577 series such as the 71V3577S75BGG8 for faster performance. Verify pinout compatibility with legacy IDT-branded equivalents like the IDT71V3577S85BGG8.
