71V3559S75BQ8

Overview

The IDT71V3559S75BQ8 is a synchronous single data rate (SDR) static random-access memory (SRAM) integrated circuit manufactured by Renesas Electronics Corporation. It features a parallel interface and is organized as 256K x 18, providing a total storage capacity of 4.5 Mbit. The device supports an access time of 7.5 ns and operates within a voltage range of 3.135 V to 3.465 V. It is housed in a 165-CABGA package measuring 13x15 mm and is rated for commercial operating temperatures between 0°C and 70°C.

Feature Summary

• Supports synchronous single data rate (SDR) operation with a parallel interface for high-speed data transfer.
• Provides 4.5 Mbit storage capacity organized as 256K words by 18 bits.
• Features fast 7.5 ns access time suitable for performance-critical applications.

Applications

• High-performance computing systems requiring fast cache memory

Procurement Notes

Verify component authenticity through authorized channels due to the part's discontinued status. Confirm RoHS compliance requirements as the specific variant may not meet current environmental standards. Ensure the 165-CABGA package dimensions align with PCB layout constraints before finalizing procurement decisions.

Selection Notes

Select this component when a 4.5 Mbit synchronous SRAM with 18-bit width is required. The 7.5 ns speed class fits designs needing moderate-to-high bandwidth. Verify that the 3.3V I/O levels match the system logic. Consider the surface-mount CABGA package for assembly compatibility.

Part Context

This part belongs to the IDT 71V3559 family of synchronous SRAMs. It shares architectural similarities with other members like the IDT71V3559SA75BQ8 but differs in specific suffix designations. The family targets embedded applications requiring reliable, fast volatile memory solutions from Renesas.
