71V65803S150PFGI

Overview

The IDT71V65803S150PFGI is a synchronous single data rate zero bus turnaround SRAM manufactured by Renesas Electronics Corporation. It provides a total storage capacity of 9 Mbit organized as 512K words by 18 bits. The device operates with a maximum clock frequency of 150 MHz and features an access time of 3.8 ns. It utilizes a parallel interface and requires a supply voltage between 3.135 V and 3.465 V. The component is housed in a 100-TQFP package measuring 14x14 mm and supports surface mount installation. It functions within a temperature range of -40°C to 85°C.

Feature Summary

• Supports high-speed synchronous operation with zero bus turnaround capability for efficient data transfer.
• Provides reliable volatile memory storage with a 9 Mbit capacity organized for wide data applications.
• Operates on a standard 3.3 V power supply rail with defined voltage tolerance limits.

Applications

• High-performance computing systems requiring fast memory access
• Network infrastructure equipment utilizing parallel SRAM interfaces
• Industrial control systems operating in extended temperature ranges

Procurement Notes

Verify the current manufacturing status before procurement, as this specific part number may be discontinued or subject to end-of-life notifications. Confirm that the 100-TQFP package dimensions match your PCB footprint requirements. Ensure that the 3.3 V supply voltage aligns with your system design specifications. Check for RoHS compliance status if environmental regulations apply to your deployment. Validate that the lead-free soldering process is compatible with the specified package type.

Selection Notes

Select this component when a 9 Mbit synchronous SRAM with a 150 MHz clock speed is required. The 512K x 18 organization suits applications needing wider data paths compared to standard 8-bit or 16-bit configurations. The 3.8 ns access time offers performance suitable for demanding processing tasks. Consider the 100-TQFP package if space constraints allow for its 14x14 mm footprint. Verify that the -40°C to 85°C operating range meets your environmental conditions.

Part Context

This device belongs to the IDT71V65803 family of synchronous SRAMs from Renesas Electronics. It shares architectural similarities with other members like the 71V65603 and 71V65903 series but differs in speed grade and organization. The family is designed for high-throughput applications requiring low latency. The specific suffix indicates the 150 MHz speed bin and TQFP packaging variant.

Replacement Considerations

Check for official substitute part numbers from Renesas if this item is unavailable. Verify compatibility regarding pinout, voltage levels, and timing parameters before substitution. Cross-reference with similar speed grades in the 71V65803 series.
