71V65603S133PFG

Overview

The IDT71V65603S133PFG is a 9 Mbit Synchronous ZBT SRAM organized as 256K x 36. It operates at a maximum clock frequency of 133 MHz with an access time of 7.5 ns. The device uses a parallel interface and requires a supply voltage between 3.135 V and 3.465 V, with a maximum current of 300 mA. It is housed in a 100-TQFP package and supports surface mount installation within a commercial temperature range of 0°C to +70°C.

Feature Summary

• Supports high-speed synchronous operation up to 133 MHz for efficient data throughput.
• Features a 36-bit wide data organization suitable for high-bandwidth memory applications.
• Includes self-timed write cycles controlled by global write enable signals.

Applications

• High-performance computing systems requiring fast cache memory
• Network infrastructure equipment needing low-latency data buffering
• Industrial control systems utilizing synchronous burst operations

Procurement Notes

Verify the specific suffix PFG against official Renesas or IDT documentation to confirm the exact package type and moisture sensitivity level. Ensure compatibility with the required 3.3V core voltage and 2.5V I/O standards if applicable. Check for RoHS compliance status and lead-free specifications relevant to your manufacturing region before finalizing procurement orders.

Selection Notes

Select this component when a 36-bit data width is required for system bus alignment. The 133 MHz speed grade offers a balance between performance and power consumption compared to faster variants. Consider the 100-pin TQFP footprint for PCB layout constraints and thermal management requirements in dense electronic assemblies.

Part Context

This part belongs to the IDT 71V65603 series of Synchronous Zero Wait State (ZBT) SRAMs. These devices are designed to provide high-speed memory solutions for complex digital systems. The series typically includes various speed grades and packaging options to accommodate different design requirements while maintaining consistent functional characteristics.

Replacement Considerations

Check for direct substitutes such as the IDT71V65603S150PFG for slower speed requirements. Verify pinout compatibility and electrical parameters before replacing with parts from other manufacturers like Renesas or ISSI.
