71V3578S150PFGI8

Overview

The 71V3578S150PFGI8 is a 4.5 Mbit synchronous single data rate static random access memory manufactured by Renesas Electronics Corporation. It features a memory organization of 256K x 18 bits and operates with a maximum clock frequency of 150 MHz, providing an access time of 3.8 ns. The device supports parallel interface communication and functions within a supply voltage range of 3.135 V to 3.465 V. It is housed in a 100-pin Thin Quad Flat Package (TQFP) with dimensions of 14x14 mm, suitable for surface mount installation.

Feature Summary

• Supports high-speed synchronous data transfer at up to 150 MHz
• Provides 4.5 Mbit storage capacity organized as 256K words by 18 bits
• Operates on standard 3.3 V I/O logic levels

Applications

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

Procurement Notes

Verify component authenticity through authorized distributors due to potential availability constraints. Confirm package integrity upon receipt, as moisture sensitivity requires proper handling. Check for specific manufacturing date codes if long-term reliability is critical. Ensure compatibility with existing board layouts before finalizing orders.

Selection Notes

Select this component when a 150 MHz synchronous SRAM with 18-bit width is required. Compare against the 71V3578S133PFGI8 for lower speed needs or the IDT71V3578S150PFI for alternative packaging options. Evaluate thermal performance within the -40°C to 85°C operating range during system design.

Part Context

This part belongs to the 71V3578 series of synchronous SRAMs from Renesas. It shares architectural similarities with other members like the 71V3578S133PFGI8 but offers higher clock speeds. The series is designed for applications demanding low latency and high throughput in parallel memory configurations.

Replacement Considerations

The IDT71V3578S150PFI is documented as a similar replacement option. Verify pinout compatibility and electrical specifications before substitution. Note that the IDT variant may differ in packaging type despite matching functional parameters.
