71T75602S133PFG

Overview

The Renesas Electronics Corporation 71T75602S133PFG is a synchronous Single Data Rate (SDR) Zero Bus Turnaround (ZBT) Static Random Access Memory (SRAM) integrated circuit. It provides an 18 Mbit storage capacity organized as 512K words by 36 bits. The device operates with a maximum clock frequency of 133 MHz and features a typical access time of 4.2 ns. It utilizes a parallel interface and requires a supply voltage range between 2.375 V and 2.625 V. The component is housed in a 100-pin Thin Quad Flat Package (TQFP) measuring 14x14 mm, designed for surface mount installation.

Feature Summary

• Supports high-speed data transfer via a parallel interface synchronized to the system clock.
• Utilizes Zero Bus Turnaround technology to minimize bus turnaround latency during read-to-write transitions.
• Operates on a dedicated 2.5V core voltage supply for stable performance.

Applications

• High-performance embedded systems requiring fast memory access
• Network infrastructure equipment
• Industrial control systems

Procurement Notes

Verify component authenticity through authorized channels due to End-of-Life status. Confirm package integrity and moisture sensitivity level handling procedures before assembly. Ensure supply chain documentation matches the specific suffix PFG for the 100-TQFP variant. Cross-reference datasheet revisions to confirm pinout compatibility with existing designs.

Selection Notes

Select this part when a 36-bit wide data path is required for processor or DSP interfaces. Compare against other ZBT SRAM families if lower power consumption or different voltage levels are needed. Verify that the 133 MHz speed grade meets the system timing requirements. Consider the 100-TQFP footprint constraints during PCB layout planning.

Part Context

This component belongs to the IDT/Renesas 71T75602 family of synchronous ZBT SRAMs. It shares architectural similarities with other members like the 71T75602S166 series but offers a specific 133 MHz operating frequency. The device represents a transition from asynchronous memories to synchronous solutions, offering improved timing predictability for complex digital systems.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Check manufacturer announcements for direct replacements within the 71T75602 series or consult distributor databases for compatible alternatives with matching pinouts and electrical characteristics.
