7052S25G

Memory IC Overview

The 7052S25G is a high-speed 16Kb (2K x 8) FourPort Static RAM manufactured by Renesas Electronics. It features four independent ports with separate control, address, and I/O pins, allowing simultaneous asynchronous access to any memory location without on-chip hardware arbitration. The device operates on a single 5V power supply with TTL-compatible levels and supports battery backup operation for data retention down to 2V. It is housed in a 132-pin PQFP package.

Memory IC Feature Summary

• True FourPort memory cells enable simultaneous access of the same memory locations from all ports
• Fully asynchronous operation allows independent read or write cycles across all four ports
• Versatile write-inhibit control via separate BUSY inputs for each individual port
• Automatic power-down feature controlled by chip enable signals for low standby power

Memory IC Applications

• Systems requiring multiple processors to access common RAM simultaneously
• High-speed data buffering where concurrent port access is necessary
• Asynchronous communication interfaces requiring independent port control

Memory IC Procurement Notes

Verify component authenticity through authorized channels as this part is obsolete. Confirm package integrity and pin compatibility during replacement planning. Check for specific suffix variations that may indicate different temperature grades or packaging types. Ensure design-in documentation aligns with the final datasheet specifications before procurement.

Memory IC Selection Notes

Select this component when simultaneous multi-port access to shared memory is required without complex arbitration logic. Consider the 132-pin PQFP package constraints for PCB layout. Evaluate power consumption requirements against the automatic power-down capabilities. Verify voltage tolerance matches the system's 5V supply rails.

Memory IC Part Context

This device belongs to the 7052 series of FourPort SRAMs designed for applications needing concurrent memory access. It provides a solution for systems where hardware port arbitration is unnecessary, offering four fully independent ports. The series supports various packages including PGA and TQFP options with different speed grades.
