71V67602S166PFG

Overview

The IDT71V67602S166PFG is a high-speed Synchronous SRAM organized as 256K x 36 bits, providing a total storage capacity of 9 Megabits. It operates with a 3.3V core power supply and supports 2.5V I/O levels. The device achieves a maximum clock frequency of 166 MHz, corresponding to a 3.5 ns clock access time. It features pipelined outputs, an internal burst counter, and single-cycle deselect capability. The component is housed in a 100-pin plastic thin quad flatpack (TQFP) package.

Feature Summary

• Supports high system speed with up to 166 MHz clock frequency
• Features pipelined outputs for improved data throughput
• Includes an internal burst address counter for sequential access
• Allows single cycle deselect for flexible control

Applications

• High-performance computing systems requiring fast memory access
• Network infrastructure equipment needing low-latency buffering
• Industrial automation controllers demanding reliable synchronous memory

Procurement Notes

Verify the exact suffix PFG against manufacturer documentation to confirm pinout and package dimensions. Ensure voltage requirements match your system design, specifically the 3.3V core and 2.5V I/O supplies. Check for RoHS compliance status if required by your manufacturing standards. Confirm availability as this part may be subject to lifecycle changes or obsolescence notices from Renesas Electronics.

Selection Notes

Select this component when a 256K x 36 organization is required for wide data paths. The 166 MHz speed grade suits applications needing 3.5 ns access times. Consider the TQFP package for surface-mount assembly compatibility. Evaluate power consumption differences between 3.3V core and 2.5V I/O options compared to other SRAM families.

Part Context

This part belongs to the IDT 71V67602/802 family of Synchronous SRAMs. These devices are designed for high-speed parallel interface applications. The family typically includes variants with different capacities and speeds, sharing common architectural features like burst counters and pipelined outputs. Renesas Electronics now manufactures these parts following the acquisition of IDT's memory business.

Replacement Considerations

Check for direct substitutes within the 71V67602 series with different speed grades or packages. Verify pin-to-pin compatibility before replacing with similar SRAMs from other manufacturers. Ensure electrical characteristics such as voltage levels and timing parameters match the original design specifications.
