7024S17J

Memory IC Overview

The Renesas Electronics Corporation 7024S17J 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 with dimensions of 29.31x29.31 mm. It supports surface mount installation and functions within a temperature range of -40°C to 85°C.

Memory IC Feature Summary

• Supports simultaneous independent reads and writes from either port without conflict
• Includes on-chip hardware semaphore signaling for inter-port synchronization
• Features automatic power-down mode controlled by chip enable signals

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, as the base model number may correspond to multiple packaging variants such as tube or tape-and-reel configurations. Confirm that the required operating temperature range aligns with the industrial grade specifications. Ensure compatibility with existing board layouts regarding the 84-pin PLCC footprint and pinout definitions before finalizing procurement decisions.

Memory IC Selection Notes

Select this component when asynchronous dual-port operation is required for shared memory resources. The 17 ns speed rating suits applications demanding rapid data exchange between processors. Consider the 84-PLCC package constraints for PCB space and thermal management. Evaluate the need for hardware semaphore support versus software-based arbitration methods for system design efficiency.

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 package options to accommodate different system timing requirements. The 7024S17J specifically targets industrial environments due to its extended temperature range capabilities. It serves as a critical memory solution for multi-processor systems requiring non-blocking data access.

Memory IC Replacement Considerations

Check for direct cross-reference part numbers from IDT or other manufacturers offering identical 64Kb dual-port specifications. Verify pin-to-pin compatibility and electrical parameter equivalence before substitution.
