71V67603S166PF

Overview

The IDT71V67603S166PF is a 9-Mbit synchronous SRAM organized as 256K x 36. It operates with a 3.3V core supply and features 2.5V I/O levels. The device supports high-speed system performance with a clock access time of 3.5 ns at 166 MHz. It utilizes a single-cycle deselect mechanism and includes pipelined outputs driven by an internal burst counter.

Feature Summary

• Supports high-performance system speeds up to 166 MHz
• Features pipelined outputs controlled by an internal burst address counter
• Enables single-cycle deselect for flexible memory management

Applications

• High-speed parallel data buffering in communication systems
• Cache memory implementation in network processors
• Data storage in embedded processing architectures

Procurement Notes

Verify the specific suffix against official Renesas or IDT documentation, as the PF designation typically indicates a plastic TQFP package. Confirm RoHS compliance status and moisture sensitivity level requirements prior to integration. Ensure voltage compatibility between the 3.3V core and 2.5V I/O domains matches the target system design specifications.

Selection Notes

Select this component when a 256K x 36 organization is required for wide-data bus applications. The 166 MHz speed grade suits designs needing low-latency synchronous access. Consider the 100-pin TQFP package constraints for PCB layout. Evaluate power consumption differences between 3.3V core and alternative voltage options if thermal management is critical.

Part Context

This part belongs to the IDT 71V676xx series of synchronous SRAMs. These devices are designed for high-throughput applications requiring deterministic access times. The series typically offers various density and speed grades, with this specific model focusing on the 36-bit width configuration for specialized data path requirements.

Replacement Considerations

Check for direct pin-compatible replacements within the same family, such as other speed grades like the S133 variant. Verify that any substitute maintains the 256K x 36 organization and 3.3V/2.5V dual-voltage operation. Consult manufacturer PCNs for potential obsolescence or packaging changes.
