7024S55GB

Memory IC Overview

The Renesas Electronics Corporation 7024S55GB is a dual-port static random-access memory (SRAM) integrated circuit. It provides a storage capacity of 64 kilobits, organized as 4K words by 16 bits. The device features asynchronous parallel interfaces for both ports, with a maximum access time of 55 nanoseconds. It operates within a supply voltage range of 4.5V to 5.5V and supports through-hole mounting in an 84-pin PGA package.

Memory IC Feature Summary

• Dual-port architecture enabling independent simultaneous access to the same memory array from two separate processors or systems.
• Asynchronous operation allows flexible timing control without reliance on a global clock signal for data transfers.
• Automatic power-down functionality controlled by Chip Enable signals reduces standby power consumption when the device is inactive.

Memory IC Applications

• High-speed data buffering between asynchronous system components
• Cache memory implementation in embedded processing systems
• Data logging applications requiring rapid write and read cycles

Memory IC Procurement Notes

Verify component authenticity due to end-of-life status. Confirm RoHS compliance requirements as the part may not meet current environmental standards. Check for valid manufacturer documentation to ensure pin compatibility with existing designs before procurement.

Memory IC Selection Notes

Select this component for designs requiring independent dual-port access to shared memory resources. Ensure the application supports asynchronous timing constraints and 5V logic levels. Verify that the 84-PGA through-hole package fits the target PCB layout and manufacturing capabilities.

Memory IC Part Context

This part belongs to the Renesas 7024S series of dual-port SRAMs. It shares architectural similarities with other members like the 7024S35G but differs in speed grade and specific packaging options. The series is designed for applications needing high-bandwidth memory sharing between multiple masters.
