7140SA35PF8

Overview

The Renesas 7140SA35PF8 is a high-speed, 8K-bit (1K x 8) dual-port static RAM. It operates with a 35 ns access time and supports parallel interface communication. The device functions within a voltage range of 4.5V to 5.5V and is designed for industrial temperature ranges. It utilizes a 64-pin TQFP surface-mount package, enabling efficient integration into systems requiring concurrent data access by two independent bus masters.

Feature Summary

• Supports simultaneous, autonomous access by two separate bus masters without conflict
• Provides high-speed asynchronous operation with 35 ns access time
• Designed for reliable performance in demanding industrial environments

Applications

• High-speed data buffering between independent processors
• FIFO applications requiring concurrent read/write operations
• Data acquisition systems needing rapid temporary storage

Procurement Notes

Verify component authenticity through authorized channels due to discontinuation status. Confirm package integrity and pin alignment against the 64-TQFP specification. Review datasheet revisions for any parameter updates prior to final design implementation.

Selection Notes

Select this component when dual-port functionality is required for 8K-bit capacity. Ensure system voltage aligns with the 4.5V to 5.5V operating range. Consider the 64-TQFP footprint constraints during PCB layout planning.

Part Context

This part belongs to the 7140SA series of dual-port SRAMs. It complements master devices like the 7130SA in complex memory architectures. The series emphasizes speed and reliability for embedded control applications.

Replacement Considerations

Check for direct equivalents such as the 7140LA35PF8 for extended temperature variants. Verify pin compatibility and electrical specifications before substitution.
