7024L55G

Memory IC Overview

The Renesas Electronics Corporation 7024L55G is a dual-port static random access memory (SRAM) integrated circuit. It features a storage capacity of 64 kilobits organized as 4K words by 16 bits. The device utilizes an asynchronous parallel interface with a maximum access time of 55 nanoseconds. It operates within a supply voltage range of 4.5V to 5.5V and supports through-hole installation in an 84-pin PGA package measuring 27.94x27.94 mm. The component is designed for commercial temperature ranges from 0°C to 70°C.

Memory IC Feature Summary

• Dual-port architecture enabling independent simultaneous read/write operations on separate ports
• Asynchronous operation eliminating the need for external clock synchronization
• Parallel data interface supporting standard bus connections

Memory IC Applications

• High-speed data buffering in communication systems
• Cache memory implementation in embedded processors
• FIFO buffer applications in industrial control networks

Memory IC Procurement Notes

Verify component authenticity due to end-of-life status. Confirm package integrity upon receipt. Check RoHS compliance documentation. Validate pin compatibility with existing PCB footprints. Review manufacturer discontinuation notices for long-term availability constraints.

Memory IC Selection Notes

Select this part when dual-port functionality is required for concurrent data handling. Ensure system voltage aligns with the 4.5V to 5.5V specification. Verify that the 55ns access time meets timing requirements. Consider the PGA-84 package dimensions for mechanical fit. Evaluate thermal performance within the commercial temperature range.

Memory IC Part Context

This component belongs to the Renesas 7024 series of dual-port SRAMs. It shares architectural similarities with other members like the 7024S55G but differs in package type and operating temperature range. The series provides non-volatile-like speed with volatile storage characteristics, serving as a bridge between fast processor speeds and slower main memory subsystems.

Memory IC Replacement Considerations

Official recommended substitutes include the 7024L20G. Verify pinout compatibility and electrical specifications before substitution. Cross-reference datasheets for any functional differences in control signals or power consumption.
