7024S45J

Memory IC Overview

The Renesas Electronics Corporation 7024S45J is a dual-port static random-access memory (SRAM) integrated circuit. It features a storage capacity of 64 kbit organized as 4K x 16 bits. The device operates with an access time of 45 ns and utilizes a parallel interface. It supports a supply voltage range from 4.5 V to 5.5 V. The component is designed for surface mount installation in an 84-PLCC package. It functions within a commercial temperature range of 0°C to +70°C.

Memory IC Feature Summary

• Supports simultaneous independent read/write operations at both Port A and Port B without conflict.
• Includes on-chip hardware arbitration logic to manage data collisions during simultaneous access.
• Features automatic power-down mode controlled by Chip Enable signals to reduce standby current.

Memory IC Applications

• High-speed data buffering in telecommunications equipment
• Cache memory implementation in embedded systems
• Data logging applications requiring fast write speeds

Memory IC Procurement Notes

Verify the specific suffix J against official documentation to confirm package type and lead material, as suffixes define physical attributes rather than function. Confirm RoHS compliance status, as this part may not meet current environmental directives. Check for End-of-Life notices or discontinuation announcements from Renesas before finalizing procurement plans.

Memory IC Selection Notes

Select this component when a dual-port architecture is required for concurrent processor access. Ensure the design accommodates the 84-PLCC footprint and 4.5V to 5.5V power requirements. Consider the 45 ns access speed relative to system clock frequencies. Verify that the commercial temperature range meets the operational environment constraints.
