71V3577S80BQI8

Overview

The Renesas Electronics Corporation 71V3577S80BQI8 is a 4.5 Mbit synchronous static random access memory (SRAM) IC organized as 128K x 36 bits. It operates with an 8 ns access time and supports clock frequencies up to 100 MHz. The device utilizes a parallel interface and functions within a supply voltage range of 3.135 V to 3.465 V. It is housed in a 165-CABGA package measuring 13x15 mm, designed for surface mount installation. The component supports an industrial operating temperature range from -40°C to +85°C.

Feature Summary

• Supports high-speed synchronous burst operations with flow-through output architecture for maximum system performance.
• Features self-timed write cycles controlled by global write control, byte write enable, and individual byte writes.
• Includes power-down functionality managed by the ZZ input pin to reduce active current consumption.

Applications

• High-performance embedded systems requiring fast data buffering
• Network infrastructure equipment utilizing parallel SRAM interfaces
• Industrial control applications operating within extended temperature ranges

Procurement Notes

Verify component authenticity through authorized channels due to end-of-life status. Confirm package integrity and moisture sensitivity level handling procedures before reflow soldering. Ensure supply chain documentation matches the specific 165-CABGA variant and electrical specifications.

Selection Notes

Select this component when a 128K x 36 organization with 8 ns latency is required. Consider the 165-CABGA footprint constraints and -40°C to +85°C thermal rating. Verify compatibility with 3.3V I/O logic levels and synchronous clock requirements.

Part Context

This part belongs to the 71V3577 family of 3.3V CMOS SRAMs. It shares architectural similarities with other variants like the 71V3577S80BG but differs in package type and temperature grade. The family emphasizes low power and high-speed burst capabilities for complex digital designs.
