7027L55PF

Memory IC Overview

The Renesas Electronics Corporation 7027L55PF is a dual-port asynchronous static random-access memory (SRAM) integrated circuit. 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 and write cycle 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 independent simultaneous access by two masters
• Asynchronous operation without clock dependency for read/write cycles
• Parallel data interface supporting standard bus connections

Memory IC Applications

• High-speed data buffering in telecommunications equipment
• Cache memory implementation in embedded processing systems
• Data logging and temporary storage in industrial control units

Memory IC Procurement Notes

Verify the specific package variant against official documentation, as sources indicate potential discrepancies between 100-TQFP and 100-LQFP designations. Confirm RoHS compliance status and moisture sensitivity level prior to integration. Ensure the supply voltage matches the required 4.5V to 5.5V range for reliable operation.

Memory IC Selection Notes

Select this component when dual-master access is required for non-volatile-like speed without the complexity of synchronous interfaces. The 55ns speed suits moderate throughput applications. Verify that the 100-pin footprint fits the board layout constraints and that the voltage levels align with the system power rails.

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 7027L25 and 7027L20 but offers slower access times. The series is designed for applications requiring independent port access to shared memory resources.

Memory IC Replacement Considerations

Direct substitutes include the 7027L20PFGI for faster performance or the 7027L25G for similar speed characteristics. Verify pin compatibility and electrical specifications before swapping.
