7027L55PFI

Memory IC Overview

The Renesas Electronics Corporation 7027L55PFI is a dual-port asynchronous static random-access memory (SRAM) integrated circuit. It provides a storage capacity of 512Kb, organized as 32K words by 16 bits. The device features a parallel interface with a maximum access time and write cycle time of 55 ns. 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-lead Thin Quad Flat Package (TQFP) with dimensions of 14x14 mm.

Memory IC Feature Summary

• Supports simultaneous independent read/write operations at both Port A and Port B for high-throughput data handling.
• Utilizes asynchronous logic to simplify system integration without requiring external clock synchronization signals.
• Designed for robust performance across extended industrial temperature ranges suitable for demanding environments.

Memory IC Applications

• High-speed data buffering in telecommunications equipment
• Cache memory implementation in embedded processing systems
• Data acquisition systems requiring rapid temporary storage

Memory IC Procurement Notes

Verify the specific suffix PFI against official Renesas documentation to confirm package type and lead-free status. Confirm RoHS compliance requirements as older variants may not meet current standards. Check for obsolescence notices or lifecycle changes directly from the manufacturer before finalizing procurement plans.

Memory IC Selection Notes

Select this component when dual-port functionality is required for concurrent master-slave or peer-to-peer data exchange. Ensure the system voltage aligns with the 4.5V to 5.5V specification. Consider the 55 ns speed adequate for the target application's timing constraints compared to faster alternatives.

Memory IC Part Context

This part belongs to the Renesas 7027L series of dual-port SRAMs. It shares architectural similarities with other members like the 7027L20 but offers slower access speeds. The series is designed for applications needing independent port access to shared memory space.

Memory IC Replacement Considerations

Direct substitutes include the 7027L20PFGI for faster performance. Verify pin compatibility and electrical specifications before substitution.
