7052L20PFGI

Memory IC Overview

The 7052L20PFGI 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, allowing simultaneous asynchronous access to any memory location without on-chip hardware arbitration. The device operates on a single TTL-compatible 5V power supply and supports battery backup operation with data retention down to 2V. It is housed in a 120-pin TQFP package and is rated for industrial temperature ranges.

Memory IC Feature Summary

• True FourPort memory cells enable simultaneous access of the same memory locations from all ports.
• Fully asynchronous operation allows independent reads or writes to any memory location via separate port controls.
• Versatile write-inhibit control includes a separate BUSY input for each of the four ports.
• Battery backup capability ensures data retention at voltages as low as 2V.

Memory IC Applications

• Systems requiring multiple processors to access common RAM simultaneously
• Hardware architectures where on-chip port arbitration is not implemented
• Industrial applications requiring wide operating temperature ranges

Memory IC Procurement Notes

Verify component authenticity through authorized channels due to potential availability constraints. Confirm package integrity upon receipt, as moisture sensitivity requires proper handling. Check for specific manufacturing date codes if long-term reliability is critical. Ensure compatibility with existing 5V logic levels before integration into final designs.

Memory IC Selection Notes

Select this component when four independent asynchronous interfaces are required for shared memory access. It is suitable for designs avoiding complex arbitration logic. Verify that the 120-pin TQFP footprint fits the PCB layout. Consider the 5V supply requirement against system voltage rails. Evaluate thermal performance within the specified industrial temperature range.

Memory IC Part Context

This part belongs to the 7052 series of FourPort SRAMs designed for high-concurrency memory access. It provides a solution for multi-processor systems needing direct, non-arbitrated access to shared data. The series supports various package options including PGA and PQFP variants for different form factor requirements.

Memory IC Replacement Considerations

Public confirmed substitute part numbers include IDT7052L20PFGI. Verify pinout and electrical specifications match exactly before substitution. Other series members like 7052L25PFGI offer different speeds but similar functionality.
