7005L20PFGI

Overview

The 7005L20PFGI is a dual-port static random-access memory integrated circuit manufactured by Renesas Electronics. It provides a storage capacity of 64 kilobits organized as 8K words by 8 bits. The device features asynchronous parallel interface with a maximum access time of 20 nanoseconds. It operates within a supply voltage range of 4.5 volts to 5.5 volts and supports surface mount installation in a 64-pin TQFP package. The component is rated for an operating temperature range from -40°C to +85°C.

Feature Summary

• Supports independent simultaneous read and write operations at both Port A and Port B without conflict.
• Provides asynchronous parallel data interface for straightforward integration into existing logic systems.
• Operates reliably across extended industrial temperature ranges suitable for harsh environments.

Applications

• Data buffering in high-speed digital signal processing architectures
• Cache memory implementation in embedded control systems
• FIFO buffer applications requiring independent port access

Procurement Notes

Verify the specific suffix configuration against the official Renesas datasheet to ensure compatibility with required voltage levels and package dimensions. Confirm RoHS compliance status for current production lots, as manufacturing updates may affect regulatory markings. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and traceability before finalizing procurement orders.

Selection Notes

Select this component when dual-port functionality is required for concurrent data handling between two independent processors or buses. Ensure the system design accommodates the specified 4.5V to 5.5V supply voltage range. Verify that the 64-TQFP package footprint aligns with the printed circuit board layout constraints and thermal management requirements of the target application environment.

Part Context

This device belongs to the 7005L series of dual-port SRAMs designed for versatile memory interfacing. It serves as a non-volatile-free storage solution where rapid data retention and independent port access are critical. The series is engineered for robust performance in industrial and commercial electronic systems requiring reliable temporary data storage.

Replacement Considerations

The 7005S25PFI is listed as an obsolete alternative. The 7005L20PFGI itself is identified as a replacement for older variants like the 7005S25PFI. No other direct substitute part numbers are confirmed in the provided documentation.
