70824L20PFI

Memory IC Overview

The 70824L20PFI is an asynchronous Static RAM (SARAM) integrated circuit manufactured by Renesas Electronics. It features a storage capacity of 128 kbit, organized as 8K words by 16 bits. The device operates with a maximum access time of 20 ns and supports parallel interface communication. It functions within a supply voltage range of 4.5 V to 5.5 V, with a maximum supply current of 320 mA. The component is designed for surface mount installation in a TQFP-80 package, measuring 14.0 x 14.0 mm with a height of 1.4 mm. It supports an operating temperature range from -40°C to +85°C.

Memory IC Feature Summary

• Provides non-volatile data retention characteristics typical of SRAM technology for rapid random access operations.
• Supports dual-port functionality allowing independent read/write access to memory cells.
• Features asynchronous operation compatible with standard parallel bus interfaces.

Memory IC Applications

• High-speed data buffering in industrial control systems
• Cache memory implementation in embedded processing units
• Data storage in telecommunications equipment

Memory IC Procurement Notes

Verify the specific suffix 'PFI' against the official Renesas datasheet to confirm pinout and electrical specifications. Confirm RoHS compliance status as historical records indicate potential non-compliance for this specific variant. Check for moisture sensitivity level requirements during handling. Ensure the source is an authorized distributor due to the component's obsolete status.

Memory IC Selection Notes

Select this component when a 128 kbit asynchronous SRAM with 20 ns access speed is required in a TQFP-80 package. It is suitable for applications needing 5V logic compatibility and wide industrial temperature ranges. Consider alternative modern equivalents if lead-free compliance or long-term availability is critical, as this part is marked obsolete.

Memory IC Part Context

This component belongs to the IDT70825/S/L series of high-speed static RAMs. It is functionally similar to the IDT70825L20PFI but differs in organization and package type. The 70824L20PFI specifically offers 8Kx16 organization in an 80-pin TQFP, whereas related parts may offer different densities or pin counts within the same family architecture.

Memory IC Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. The component is listed as obsolete. Designers should consult Renesas for current recommended replacements or evaluate cross-reference options based on pin compatibility and electrical parameters.
