7052L20PFG

Memory IC Overview

The Renesas Electronics Corporation 7052L20PFG is a high-speed 2K x 8 FourPort Static RAM designed for systems requiring multiple simultaneous accesses to common memory locations. It features four independent ports with separate control, address, and I/O pins, allowing asynchronous read or write operations to any memory location without on-chip hardware arbitration. The device operates on a single 5V power supply and supports battery backup operation with data retention down to 2V.

Memory IC Feature Summary

• True FourPort memory cells enable simultaneous access of the same memory locations from all ports.
• Fully asynchronous operation allows independent control for each of the four ports.
• Versatile write-inhibit control via separate BUSY inputs for each port.

Memory IC Applications

• Systems requiring multiple processors to access shared memory simultaneously
• Hardware port arbitration is not needed in the design architecture
• Applications requiring independent asynchronous reads or writes to common memory

Memory IC Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and humidity sensitivity handling requirements prior to assembly. Review official discontinuance notifications as this part may be obsolete. Ensure ESD protection protocols are followed during storage and installation.

Memory IC Selection Notes

Select this component when true simultaneous multi-port access is required without external arbitration logic. Suitable for designs needing independent control over write-inhibit states per port. Verify package availability as it comes in TQFP-120 format. Consider industrial temperature range options if operating conditions exceed commercial limits.

Memory IC Part Context

This SRAM belongs to the 7052 series, which provides versatile four-port memory solutions. The L20 designation indicates a 20ns access time variant within the family. It serves as a specialized memory solution for complex embedded systems where traditional single-port or dual-port memories create bottlenecks due to arbitration overhead.

Memory IC Replacement Considerations

Check for IDT7052L20PFG as an alias. Verify pin compatibility and electrical specifications against current inventory alternatives. Consult official datasheets for any functional differences between legacy and replacement parts.
