71V3577S75BQG8

Overview

The IDT71V3577S75BQG8 is a synchronous single data rate (SDR) static random-access memory integrated circuit manufactured by Renesas Electronics Corporation. It features a storage capacity of 4.5 megabits organized as 128K words by 36 bits. The device supports parallel interface operations with a maximum access time of 7.5 nanoseconds and a clock frequency of 117 MHz. It operates within a supply voltage range of 3.135 volts to 3.465 volts and is designed for surface-mount installation in a 165-pin CABGA package measuring 13x15 millimeters.

Feature Summary

• Supports synchronous burst mode operation providing four cycles of data for a single address presentation
• Includes self-timed write cycle functionality with global write control and byte write enable capabilities
• Features low power down control managed via the ZZ input pin

Applications

• High-performance embedded systems requiring fast data retrieval
• Industrial network solutions utilizing synchronous memory interfaces
• Real-time engine applications demanding low latency access

Procurement Notes

Verify component authenticity through authorized distributors due to end-of-life status. Confirm moisture sensitivity level classification and reflow soldering profiles prior to assembly. Ensure compatibility with existing board layouts given the specific 165-pin CABGA footprint dimensions. Review official product change notices for any labeling or substrate modifications that may affect integration.

Selection Notes

Select this component when a 36-bit wide data bus is required for system architecture. Consider the 7.5 ns access speed for timing constraints in high-frequency designs. Evaluate the 165-pin BGA package size against available PCB real estate. Compare power consumption characteristics against alternative SRAM families if thermal management is critical.
