7024L55JI

Memory IC Overview

The Renesas 7024L55JI is a dual-port asynchronous static random-access memory (SRAM) integrated circuit. It provides a storage capacity of 64 kilobits, organized as 4096 words by 16 bits. The device features a parallel interface with a maximum access time of 55 nanoseconds. It operates within a supply voltage range of 4.5 volts to 5.5 volts and supports an industrial operating temperature range from -40°C to +85°C. The component is housed in an 84-lead Plastic Leadless Chip Carrier (PLCC) package measuring 29.31mm by 29.31mm.

Memory IC Feature Summary

• Dual-port architecture enabling independent simultaneous access to the same memory array via two separate port sets.
• Asynchronous operation allowing flexible timing control without reliance on a global clock signal.
• CMOS technology implementation ensuring low power consumption relative to older bipolar SRAM alternatives.

Memory IC Applications

• High-speed data buffering in telecommunications equipment requiring concurrent read/write operations.
• Cache memory subsystems in embedded systems where independent processor access is necessary.
• Industrial control units operating in extended temperature environments demanding reliable volatile storage.

Memory IC Procurement Notes

Verify the specific suffix JI against official Renesas documentation to confirm package type and temperature grade. Confirm RoHS compliance status for current production lots, as legacy variants may differ. Check for End-of-Life notices or Product Change Notifications that may affect long-term availability. Ensure the ordering part number matches the exact speed grade and pin configuration required for your design.

Memory IC Selection Notes

Select this component when a system requires true dual-port functionality for concurrent data handling without external arbitration logic. The 55ns access speed suits moderate-to-high frequency applications where absolute lowest latency is not the primary constraint. Verify that the 84-pin PLCC footprint fits the target PCB layout constraints. Consider the 4.5V to 5.5V supply requirement for compatibility with existing logic levels.

Memory IC Part Context

This device belongs to the Renesas 7024L series of high-performance dual-port SRAMs. The series offers various speed grades to accommodate different system timing requirements while maintaining a consistent pinout and functional architecture. These components are designed for applications requiring high throughput and independent port access.

Memory IC Replacement Considerations

Cross-reference with IDT7024L55JI for potential pin-compatible alternatives from former Integrated Device Technology lines. Verify electrical parameters and package dimensions before substitution. Consult Renesas for current recommended replacements if this specific part is discontinued.
