71V65803S133PFG

Overview

The IDT71V65803S133PFG is a 9-Mbit synchronous static random-access memory (SRAM) device organized as 512K words by 18 bits. It operates at a maximum clock frequency of 133 MHz with a typical access time of 4.2 ns. The component utilizes a single data rate (SDR) Zero Bus Transition (ZBT) architecture 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 14 mm x 14 mm.

Feature Summary

• Supports high-speed parallel data transfer via SDR ZBT technology
• Features burst counter flow-through output mode for efficient sequential access
• Enables single-cycle deselect capability to reduce power consumption during idle states

Applications

• High-performance embedded systems requiring fast local memory
• Network infrastructure equipment such as routers and switches
• Industrial automation controllers needing rapid data processing

Procurement Notes

Verify the specific suffix 'PFG' against official Renesas documentation to confirm package type and temperature grade, as ordering codes may vary across distributors. Confirm RoHS compliance status, as older batches may not meet current environmental standards. Check for active obsolescence notices or product change notifications (PCN) from the manufacturer before finalizing procurement plans.

Selection Notes

Select this component when a 18-bit wide interface is required for system compatibility. Ensure the design supports 3.3 V logic levels and 133 MHz clock speeds. Consider thermal management requirements for the TQFP-100 package if operating near the upper temperature limits. Verify that the host controller supports the specific burst modes and control signals defined in the datasheet.

Part Context

This part belongs to the IDT 71V65803 family of synchronous SRAMs, which are designed for applications demanding high bandwidth and low latency. The family typically includes variants with different access times and package options, such as BGA or LQFP, allowing designers to optimize for board space and performance constraints while maintaining pin-to-pin compatibility within the same speed grade.

Replacement Considerations

Direct substitutes include other 133 MHz, 18-bit synchronous SRAMs in a 100-TQFP package. Verify electrical parameters and pinout compatibility carefully. Alternative packages like BGA may require PCB redesign.
