7052L25PFGI8

Memory IC Overview

The 7052L25PFGI8 is a high-speed 2K x 8 FourPort Static RAM featuring true four-port memory cells for simultaneous access to identical locations. It operates asynchronously with separate control, address, and I/O pins for each port, eliminating the need for on-chip hardware arbitration. The device supports battery backup with 2V data retention and includes an automatic power-down feature controlled by chip enable inputs. It functions within an industrial temperature range of -40°C to +85°C.

Memory IC Feature Summary

• True FourPort architecture enabling simultaneous independent asynchronous reads or writes to any memory location
• Versatile write-inhibit control via separate BUSY inputs for each of the four ports
• Automatic low-power standby mode activated by chip enable signals
• TTL-compatible single 5V power supply operation

Memory IC Applications

• Systems requiring multiple concurrent accesses to common RAM without hardware arbitration
• Industrial applications operating in extreme temperature environments
• Battery-backed memory systems requiring data retention at low voltages

Memory IC Procurement Notes

Verify component status as this part may be obsolete. Confirm package type and lead-free compliance against current manufacturer documentation. Check for moisture sensitivity level requirements during storage and handling. Ensure substitute parts are validated for pin compatibility and electrical specifications before integration into existing designs.

Memory IC Selection Notes

Select this component when independent asynchronous access from four distinct interfaces is required. It is suitable for designs where external arbitration logic would otherwise increase complexity. Consider the 120-pin TQFP package constraints and industrial temperature rating for environmental suitability.

Memory IC Part Context

This device belongs to the 7052 series of high-speed static random-access memories. It is designed for applications demanding high throughput through parallel independent port access. The FourPort technology distinguishes it from standard dual-port SRAMs by providing four fully independent data paths.

Memory IC Replacement Considerations

Public confirmed substitutes include 7052L20PFGI8 and 7052L35PFGI8. Verify timing parameters and package compatibility when transitioning between these variants.
