7027S20PFI

Memory IC Overview

The 7027S20PFI is a dual-port static random-access memory (SRAM) integrated circuit manufactured by Renesas Electronics Corporation. It features a storage capacity of 256 kilobits organized as 32K words by 8 bits. The device utilizes an asynchronous parallel interface with a maximum access time of 20 nanoseconds. It operates within a supply voltage range of 4.5V to 5.5V and is housed in an 80-lead Thin Quad Flat Package (TQFP) measuring 14x14 mm. The component supports surface-mount installation and is rated for an industrial operating temperature range from -40°C to +85°C.

Memory IC Feature Summary

• Dual-port architecture enabling independent simultaneous read/write operations on separate ports
• Asynchronous operation allowing flexible timing control without external clock synchronization
• Parallel interface supporting standard data bus widths for direct microprocessor connection

Memory IC Applications

• High-speed data buffering in communication systems
• Cache memory implementation in embedded processing units
• Data logging applications requiring rapid write cycles

Memory IC Procurement Notes

Verify RoHS compliance status carefully, as the source indicates non-compliance with current environmental directives. Confirm package marking updates via Product Change Notices. Check for authorized distributors offering legacy stock or qualified replacement alternatives such as the 7007L series. Ensure supply chain stability due to obsolete manufacturing status.

Memory IC Selection Notes

Select this component when dual-port functionality is required for concurrent master-slave memory access. Compare against single-port SRAMs if only one processor accesses the memory. Evaluate the 20ns access speed against system clock requirements. Consider the 80-TQFP package constraints for PCB layout density and thermal management capabilities.

Memory IC Part Context

This part belongs to the Renesas 7027/7007 family of dual-port SRAMs. It serves as a legacy solution for designs requiring independent port access. The 'S' suffix typically denotes specific packaging or environmental variants within the broader product line. It complements other memory solutions like the 7027L series which may offer updated regulatory compliance.

Memory IC Replacement Considerations

The 7007L20PFGI is identified as an upgrade alternative. Verify pin compatibility and electrical specifications before substitution. Ensure the replacement meets current RoHS standards if required by the final application.
