71V65603S133PF

Overview

The IDT71V65603S133PF is a 9Mbit Synchronous ZBT SRAM organized as 256K x 36. It operates at a clock frequency of 133MHz with a 4.2ns access time. The device uses a 3.3V core supply and supports parallel interface communication. It is housed in a 100-TQFP (14x14) package and functions within a commercial temperature range of 0°C to 70°C.

Feature Summary

• Supports high-speed synchronous data transfer via ZBT technology
• Features internal burst address counter for sequential data access
• Includes self-timed write cycle capability with global write control

Applications

• High-performance computing systems requiring fast cache memory
• Network infrastructure equipment needing low-latency buffering
• Industrial automation controllers utilizing synchronous logic interfaces

Procurement Notes

Verify the specific suffix 'PFG' against official Renesas or IDT documentation to confirm pinout compatibility and RoHS status, as variations exist within the 71V65603 family. Confirm that the 133MHz speed grade matches system timing requirements. Check for obsolescence notices from the manufacturer before finalizing procurement plans.

Selection Notes

Select this component when a 256K x 36 organization is required for wide-data bus applications. Ensure the design accommodates the 3.3V core voltage and 100-pin TQFP footprint. Compare against other speed grades like 150MHz if higher throughput is needed, while verifying thermal management capabilities for the specified operating temperature range.

Part Context

This part belongs to the IDT 71V65603 series of 3.3V Synchronous ZBT SRAMs. It shares architectural similarities with the 71V65803 but differs in data width configuration. The series is designed for embedded applications demanding high bandwidth and low power consumption compared to asynchronous alternatives.

Replacement Considerations

Check for direct equivalents such as the ISSI IS61NLP25636B-200TQLI, noting differences in speed grade and package type. Verify pin-to-pin compatibility and electrical specifications before substitution.
