71V3577S85BQI

Overview

The Renesas Electronics Corporation 71V3577S85BQI is a 4.5 Mbit synchronous static random access memory (SRAM) organized as 128K x 36 bits. It operates with a maximum clock frequency of 87 MHz and features an access time of 8.5 ns. The device utilizes a parallel interface and requires a supply voltage between 3.135 V and 3.465 V. It is housed in a 165-CABGA package measuring 13x15 mm, designed for surface mount installation.

Feature Summary

• Supports burst mode operations providing four cycles of data for a single address to enhance system performance
• Features self-timed write cycles controlled by global write control, byte write enable, and byte writes
• Includes optional boundary scan JTAG interface compliant with IEEE 1149.1 standards

Applications

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

Procurement Notes

Verify component authenticity through authorized channels due to end-of-life status. Confirm RoHS compliance requirements as the device may not meet current environmental regulations. Check for moisture sensitivity level handling procedures during assembly. Ensure supply chain stability given potential discontinuation risks associated with legacy memory products.

Selection Notes

Select this component when a 128K x 36 organization is required with 8.5 ns access speed. Consider the 165-CABGA package constraints for PCB layout. Evaluate power consumption against system thermal limits. Compare alternative synchronous SRAM options if newer RoHS-compliant versions are mandatory for the target application.
