70824S25PFI

Memory IC Overview

The IDT70824S25PFI is a static RAM (SARAM) memory integrated circuit manufactured by Renesas Electronics Corporation. It features a parallel interface and a storage capacity of 64Kb, organized as 4K words by 16 bits. The device operates within a supply voltage range of 4.5V to 5.5V and supports an access time of 25ns. It is housed in an 80-TQFP package with dimensions of 14x14mm. The component is designed for surface mount installation and functions within a temperature range of 0°C to 70°C.

Memory IC Feature Summary

• Provides high-speed asynchronous parallel data access with a 25ns cycle time.
• Utilizes SARAM technology for volatile data retention.
• Designed for surface-mount integration via an 80-pin TQFP footprint.

Memory IC Applications

• Data buffering in embedded systems
• Cache memory implementation
• High-speed temporary storage in industrial control units

Memory IC Procurement Notes

Verify the specific suffix 'I' against official documentation, as the primary available datasheet references the 'F' variant. Confirm RoHS compliance status, as the 'F' version is explicitly listed as non-compliant. Check for obsolescence notices, as related parts in this series have been discontinued. Ensure the required operating temperature range aligns with the commercial grade specifications found in public records.

Memory IC Selection Notes

Select this component when a 64Kb parallel SRAM with 25ns speed is required in an 80-pin form factor. Compare against the 70824L20PF for lower speed options or different temperature ratings. Verify that the 4.5V to 5.5V supply voltage matches the system design constraints. Consider the commercial temperature range limitations if the application requires extended environmental operation.

Memory IC Part Context

This part belongs to the IDT70824 family of static RAM devices. The family includes variants such as the 70824S25PF and 70824L20PF, which share similar architectural features but differ in speed grades and temperature ranges. These components are typically used in applications requiring fast, random-access memory capabilities within compact surface-mount packages.
