7024S17JI

Memory IC Overview

The Renesas Electronics Corporation 7024S17JI is a dual-port static random-access memory (SRAM) integrated circuit. It features a storage capacity of 64Kb organized as 4K words by 16 bits. The device utilizes a parallel interface with an access time and write cycle time of 17 ns. 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-PLCC package, measuring 29.31x29.31 mm, and supports surface mount installation. It functions asynchronously and is rated for an operating temperature range from -40°C to +85°C.

Memory IC Feature Summary

• Supports simultaneous independent reads and writes from either port without bus contention
• Includes on-chip hardware arbitration logic for semaphore signaling between ports
• Provides separate upper-byte and lower-byte control for multiplexed bus compatibility

Memory IC Applications

• High-speed data buffering in telecommunications systems
• Cache memory implementation in embedded processing architectures
• Data logging applications requiring concurrent port access

Memory IC Procurement Notes

Verify the specific suffix designation against official documentation to confirm package type and temperature grade. Confirm RoHS compliance status as indicated in current manufacturer notices. Check for product discontinuance notifications or end-of-life announcements prior to finalizing procurement plans. Ensure moisture sensitivity level handling procedures are followed during assembly.

Memory IC Selection Notes

Select this component when asynchronous dual-port operation with 17 ns speed is required. Consider the 84-PLCC package constraints for board layout. Evaluate the 4.5V to 5.5V supply requirement against system power rails. Verify that the industrial temperature range meets environmental specifications.

Memory IC Part Context

This part belongs to the 7024 series of dual-port SRAMs manufactured by Renesas Electronics. The series offers various speed grades and packaging options. The 7024S17JI specifically denotes the 17 ns speed variant in the PLCC package format. It serves as a standalone memory solution or can be configured in master/slave arrangements for wider data buses.

Memory IC Replacement Considerations

Consult official datasheets for pin-compatible alternatives within the same series. Verify electrical parameter equivalence for access time and voltage ranges. Check for updated package dimensions if transitioning to different manufacturers.
