71V3578S133PFGI8

Overview

The 71V3578S133PFGI8 is a 4 Mbit (256K x 18) synchronous static random access memory manufactured by Renesas Electronics. It operates with a maximum clock frequency of 133 MHz and features a typical access time of 4.2 ns. The device utilizes a parallel interface and requires a supply voltage range of 3.135 V to 3.465 V. It is housed in a 100-TQFP package with dimensions of 14x14 mm and supports surface mount installation.

Feature Summary

• Supports high-speed data transfer via a 133 MHz synchronous single data rate interface
• Provides fast memory access with a 4.2 ns typical access time
• Operates within a standard 3.3 V power supply range for compatibility

Applications

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

Procurement Notes

Verify component authenticity through authorized distributors as the part status is End-of-Life. Confirm package integrity upon receipt, as moisture sensitivity level 3 requires proper handling. Ensure supply chain documentation matches the specific suffix PFGI8 for correct pinout and electrical specifications.

Selection Notes

Select this component when a 256K x 18 organization is required for synchronous applications. Compare against other 71V3578 variants based on package type and speed grade. Ensure the design accommodates the 100-TQFP footprint and thermal requirements associated with synchronous SRAM operation at 133 MHz.

Part Context

This part belongs to the Renesas 71V3578 family of synchronous SRAMs. It shares architectural similarities with other members like IDT71V3578YS133PF8 but differs in packaging and specific manufacturing revisions. The family targets applications demanding high bandwidth and low latency memory solutions.

Replacement Considerations

Public confirmed substitute part numbers are not available for this end-of-life component.
