7052S20PFGI

Memory IC Overview

The 7052S20PFGI is a high-speed 2K x 8 FourPort Static RAM manufactured by Renesas Electronics. It features four independent ports with separate control, address, and I/O pins for asynchronous access. The device operates on a single 5V power supply (4.5V to 5.5V) with a maximum access time of 20 ns. It is housed in a 120-pin TQFP package and supports industrial temperature ranges.

Memory IC Feature Summary

• True FourPort memory cells allow simultaneous access of the same memory locations
• Fully asynchronous operation from each of the four ports
• Versatile control for write-inhibit with separate BUSY input for each port
• Automatic power down feature controlled by CE for low power standby mode

Memory IC Applications

• Systems requiring multiple access into a common RAM
• Applications where on-chip hardware port arbitration is not needed
• Battery backup operations with 2V data retention

Memory IC Procurement Notes

Verify component authenticity through authorized channels as this part may be obsolete or end-of-life. Confirm package integrity and lead condition upon receipt. Check datasheet revisions for any specific handling instructions related to static discharge sensitivity during assembly and testing processes.

Memory IC Selection Notes

Select this component when independent asynchronous access to shared memory is required without complex arbitration logic. Ensure the design accommodates the 120-pin TQFP footprint and 5V supply requirements. Consider thermal management for industrial temperature ranges if operating near limits.

Memory IC Part Context

Part of the 7052 series of FourPort SRAMs designed for high-speed multi-port memory applications. The series offers various access times and package options to suit different system performance and form factor constraints while maintaining compatibility with standard TTL logic levels.

Memory IC Replacement Considerations

Check for direct pin-compatible substitutes within the 7052 family such as 7052L20PFGI or 7052S35PQF. Verify that alternative parts maintain the same FourPort architecture and voltage specifications before integration.
