7027S55PF8

Memory IC Overview

The 7027S55PF8 is an asynchronous dual-port static random-access memory (SRAM) integrated circuit manufactured by Renesas Electronics. It provides a total storage capacity of 512 kilobits, organized as 32K words by 16 bits. The device features parallel interface access with a maximum access time of 55 nanoseconds. It operates within a supply voltage range of 4.5V to 5.5V and supports an industrial operating temperature range from -40°C to +85°C. The component is housed in a 100-pin Thin Quad Flat Package (TQFP) measuring 14x14 mm.

Memory IC Feature Summary

• Dual-port architecture enabling simultaneous independent access to the same memory location by two separate systems.
• Asynchronous operation allowing flexible timing control without requiring a global clock signal.
• Parallel data interface supporting standard bus protocols for straightforward integration.

Memory IC Applications

• High-speed data buffering between asynchronous system components
• Network equipment packet storage and processing
• Industrial automation controller memory expansion

Memory IC Procurement Notes

Verify the specific suffix 'F8' against the manufacturer's official documentation to confirm tape-and-reel packaging specifications. Ensure the required supply voltage and temperature grade align with the target application environment before finalizing procurement decisions.

Memory IC Selection Notes

Select this component when simultaneous bidirectional or unidirectional data transfer is required between two processors. The 55ns access speed suits moderate-to-high throughput applications. Confirm that the 100-pin TQFP footprint fits the printed circuit board layout constraints.

Memory IC Part Context

This part belongs to the Renesas 7027 series of dual-port SRAMs. These devices are designed for applications requiring high-speed data sharing between microprocessors, digital signal processors, or field-programmable gate arrays without complex arbitration logic.

Memory IC Replacement Considerations

Consult official Renesas obsolescence notices for valid substitute part numbers. Verify pin compatibility and electrical parameters if considering alternative manufacturers.
