7024S20JI

Memory IC Overview

The Renesas 7024S20JI is a dual-port static random access memory (SRAM) integrated circuit. It provides a storage capacity of 64 kbit, organized as 4k words by 16 bits. The device features asynchronous parallel interfaces for both Port A and Port B, with a maximum access time of 20 ns. It operates within a supply voltage range of 4.5 V to 5.5 V. The component is housed in an 84-lead Plastic Leadless Chip Carrier (PLCC) package designed for surface-mount technology applications.

Memory IC Feature Summary

• Dual-port architecture enabling independent simultaneous access via separate Port A and Port B interfaces.
• Asynchronous operation allowing flexible integration into systems without strict clock synchronization requirements.
• Parallel data interface supporting standard 16-bit word width for efficient data throughput.

Memory IC Applications

• High-speed data buffering in telecommunications equipment
• Cache memory implementation in industrial control systems
• Data storage in network infrastructure devices

Memory IC Procurement Notes

Verify the specific suffix 'JI' against official Renesas documentation to confirm the exact package variant and temperature rating. Confirm RoHS compliance status as legacy components may have varying environmental declarations. Check current production status, as this part number may be subject to discontinuation or obsolescence notices from the manufacturer.

Memory IC Selection Notes

Select this component when a dual-port SRAM solution is required for systems needing concurrent read/write operations on separate ports. Ensure the design supports 5V logic levels and accommodates the 84-PLCC footprint. Verify that the 20 ns access time meets the system timing constraints for both ports operating independently.

Memory IC Part Context

The 7024S20 belongs to the Renesas 7024S series of high-performance dual-port SRAMs. This family is designed for applications requiring fast, non-volatile-like performance with the flexibility of dual access points. The series typically includes variants with different access speeds and packaging options to suit various embedded system requirements.

Memory IC Replacement Considerations

Official cross-reference data indicates IDT7024S20JI as a compatible substitute part number. Verify pin compatibility and electrical specifications before substitution.
