7024S35JI

Memory IC Overview

The Renesas Electronics Corporation 7024S35JI is a dual-port static random-access memory (SRAM) device with a storage capacity of 64 kbit, organized as 4K x 16. It features an asynchronous parallel interface with a maximum access time of 35 ns. The component operates on a single 5V power supply within a voltage range of 4.5 V to 5.5 V. Designed for commercial applications, it supports a temperature range from 0°C to +70°C. The device is housed in an 84-pin Plastic Leaded Chip Carrier (PLCC) package with J-leads, suitable for surface mount installation.

Memory IC Feature Summary

• True dual-port architecture enabling simultaneous independent reads and writes from either port without bus contention.
• Integrated hardware support for semaphore signaling and port arbitration logic to manage data integrity between ports.
• On-chip interrupt flag functionality to signal status conditions such as busy states or write completion.

Memory IC Applications

• High-speed data buffering in telecommunications equipment requiring low-latency access.
• Cache memory implementation in embedded systems utilizing 16-bit data buses.
• Master/Slave dual-port configurations for expanding word widths in industrial control systems.

Memory IC Procurement Notes

Verify the specific suffix 'JI' against official Renesas documentation to confirm the exact temperature grade and lead finish specifications. Confirm current production status as legacy components may be subject to discontinuation notices. Ensure compatibility with existing PCB footprints for 84-PLCC packages during design validation.

Memory IC Selection Notes

Select this component when a true dual-port SRAM with 4K x 16 organization and 35 ns speed is required for commercial temperature environments. Consider the PLCC package constraints for surface mount assembly processes. Evaluate alternative members of the 7024S/L series if different access times or industrial temperature ranges are needed.
