7007S20JI

Memory IC Overview

The Renesas 7007S20JI is a dual-port asynchronous SRAM memory IC with a 256Kbit capacity organized as 32K x 8. It features a parallel interface and offers a 20 ns access time. The device operates within a 4.5V to 5.5V supply voltage range and supports an operating temperature of 0°C to 70°C. It is housed in a 68-PLCC package (24.21x24.21 mm) designed for surface-mount installation.

Memory IC Feature Summary

• Dual-port architecture enabling independent simultaneous access by two processors
• Asynchronous operation without requiring a system clock signal
• Parallel data interface for high-speed data transfer

Memory IC Applications

• High-performance embedded systems requiring shared memory
• Industrial automation controllers
• Telecommunications equipment buffer storage

Memory IC Procurement Notes

Verify component authenticity through authorized distributors due to end-of-life status. Confirm RoHS compliance requirements as the part may not meet current environmental standards. Validate package dimensions against PCB footprint specifications before integration into new designs.

Memory IC Selection Notes

Select this component when dual-port functionality is required for concurrent processor access. Ensure voltage levels match the 4.5V to 5.5V operational range. Consider the 68-PLCC package constraints for board layout and thermal management during system design.

Memory IC Part Context

This part belongs to the Renesas 7007S series of dual-port SRAMs. It shares architectural similarities with the 7007S20G but differs in packaging, utilizing PLCC instead of PGA. The series provides non-volatile-like speed with volatile memory characteristics for temporary data storage.

Memory IC Replacement Considerations

Direct substitutes include the IDT7007S20JI. Verify pin compatibility and electrical parameters before substitution. Check availability from alternative manufacturers offering equivalent dual-port SRAM solutions.
