71V65603S150PFGI

Overview

The Renesas Electronics Corporation 71V65603S150PFGI is a 9Mb Synchronous ZBT SRAM IC organized as 256K x 36. It operates with a maximum clock frequency of 150 MHz and features a typical access time of 3.8 ns. The device utilizes a parallel interface and requires a supply voltage range of 3.135V to 3.465V. It is housed in a 100-TQFP (14x14) surface-mount package. The component supports an operating temperature range of -40°C to 85°C.

Feature Summary

• Supports synchronous single data rate (SDR) operations for high-speed data transfer
• Zero bus turnaround (ZBT) architecture eliminates dead cycles during read/write transitions
• Provides pipelined output structure for improved throughput efficiency

Applications

• High-performance computing systems requiring fast memory access
• Network infrastructure equipment utilizing wide data buses
• Industrial control systems needing reliable volatile storage

Procurement Notes

Verify the specific suffix PFGI against official Renesas documentation to confirm pinout and electrical characteristics, as variations exist within the family. Confirm RoHS compliance status for the specific manufacturing date code, as legacy stock may differ from current production standards. Ensure compatibility with existing board layouts regarding the 100-TQFP footprint before procurement.

Selection Notes

Select this component when a 36-bit wide data path is required for system integration. The 150 MHz speed grade offers a balance between performance and power consumption compared to higher-frequency variants. Consider the -40°C to 85°C industrial temperature rating for environments exceeding commercial limits. Evaluate the 3.3V core voltage requirements against available power rails.

Part Context

This part belongs to the IDT/Renesas 71V65603 series of 3.3V CMOS synchronous SRAMs. These devices are designed to eliminate dead bus cycles, making them suitable for applications requiring frequent direction changes on the data bus. The series typically includes various speed grades and package options to support diverse embedded memory needs.

Replacement Considerations

Official substitutes include the 71V65703S80PFGI and 71V65703S85PFGI from Renesas. Verify pin compatibility and timing parameters before substitution.
