7024S55JI8

Memory IC Overview

The Renesas Electronics Corporation 7024S55JI8 is a dual-port static random access memory (SRAM) device. It features a storage capacity of 64 kbit, organized as 4K words by 16 bits. The component supports parallel asynchronous interfaces with a maximum access time of 55 ns. It operates within a supply voltage range of 4.5 V to 5.5 V and is designed for surface-mount installation in an 84-pin PLCC package. The device functions reliably across an industrial temperature range from -40°C to +85°C.

Memory IC Feature Summary

• Dual-port architecture enabling independent simultaneous access to the same memory array
• Asynchronous parallel interface supporting standard logic levels
• Industrial-grade temperature rating for extended environmental operation

Memory IC Applications

• High-speed data buffering in telecommunications equipment
• Cache memory implementation in embedded processing systems
• Data logging applications requiring rapid write cycles

Memory IC Procurement Notes

Verify component authenticity through authorized channels due to discontinuation status. Confirm RoHS compliance requirements against specific project standards, as this variant may not meet current directives. Validate pin compatibility and electrical specifications against existing designs before integration. Check for available obsolescence notices or last-time buy notifications from the manufacturer.

Memory IC Selection Notes

Select this component when dual-port functionality is required for concurrent master-slave operations. Ensure the design accommodates the 84-PLCC footprint and 55 ns timing constraints. Verify that the 4.5 V to 5.5 V supply range aligns with the system power architecture. Consider the industrial temperature range if the application environment exceeds commercial limits.

Memory IC Part Context
