7024L55GB

Memory IC Overview

The 7024L55GB is a dual-port static random access memory (SRAM) integrated circuit manufactured by Renesas Electronics. It provides a storage capacity of 64 kilobits, organized as 4K words by 16 bits. The device features asynchronous parallel interfaces for both ports, allowing independent read and write operations. It supports a supply voltage range of 4.5V to 5.5V and has a maximum access time of 55 nanoseconds. The component is housed in an 84-pin Plastic Leadless Chip Carrier (PLCC) package with dimensions of 29.31mm x 29.31mm. It operates within a temperature range of -40°C to +85°C.

Memory IC Feature Summary

• Dual-port architecture enabling simultaneous independent access from two distinct systems
• Asynchronous operation eliminating the need for external clock synchronization
• Parallel interface supporting standard data bus connections

Memory IC Applications

• High-speed data buffering between asynchronous logic blocks
• Cache memory implementation in embedded processing systems
• Data storage in industrial control applications requiring wide operating temperatures

Memory IC Procurement Notes

This component is officially discontinued and no longer in production. Verification of availability should focus on surplus or secondary market sources rather than direct manufacturer distribution. Buyers must confirm the authenticity of the part number alias IDT7024L55GB when sourcing from third-party vendors. Ensure that any acquired units match the original RoHS non-compliant specifications and PGA-84/PLCC packaging details before integration into designs.

Memory IC Selection Notes

Engineers selecting this part should consider its specific 55ns access speed and 4Kx16 organization. The 84-PLCC package requires appropriate surface-mount footprints. Due to the discontinuation status, alternative components with similar dual-port capabilities and compatible voltage ranges must be evaluated for pin-to-pin compatibility or functional equivalence in existing hardware architectures.

Memory IC Part Context

The 7024L55GB belongs to the 7024L series of dual-port SRAMs from Renesas Electronics. This series is characterized by high-speed asynchronous operation and robust performance in demanding environments. The device serves as a specialized memory solution for applications requiring concurrent data access without complex arbitration logic.
