7024L45J

Memory IC Overview

The Renesas Electronics Corporation 7024L45J is a dual-port static random-access memory (SRAM) integrated circuit. It provides a storage capacity of 64 kilobits, organized as 4K words by 16 bits. The device features asynchronous parallel interface operation with a maximum access time of 45 nanoseconds. It operates on a single 5V power supply within a voltage range of 4.5V to 5.5V. The component is housed in an 84-lead Plastic Leadless Chip Carrier (PLCC) package, measuring 29.31mm by 29.31mm. It supports surface mount installation and functions within a commercial temperature range of 0°C to 70°C.

Memory IC Feature Summary

• True dual-port architecture enables simultaneous independent read and write operations from either port without bus contention.
• On-chip hardware semaphore signaling and arbitration logic facilitate data synchronization between the two ports.
• TTL-compatible inputs and outputs allow direct interfacing with standard digital logic families.
• Automatic power-down mode reduces standby current consumption when chip enable signals are inactive.

Memory IC Applications

• High-speed data buffering in telecommunications equipment
• Cache memory implementation in embedded processing systems
• Data logging applications requiring rapid sequential access
• Multiprocessor system interconnects for shared resource management

Memory IC Procurement Notes

Verify component authenticity through authorized distributors or manufacturer channels due to end-of-life status. Confirm package integrity and moisture sensitivity level handling procedures prior to assembly. Review official datasheets for pinout compatibility and electrical specifications against current design requirements. Ensure compliance with relevant environmental regulations applicable to legacy components.

Memory IC Selection Notes

Select this component for designs requiring independent concurrent access to shared memory resources. Evaluate the 45ns access speed against system timing constraints. Consider the 84-PLCC package dimensions for PCB layout space availability. Assess thermal performance within the specified commercial temperature range. Verify power supply stability within the 4.5V to 5.5V operating window.

Memory IC Part Context

This part belongs to the 7024L series of dual-port SRAMs manufactured by Renesas Electronics. The series offers various access speeds and packaging options to suit different performance and form factor requirements.
