7027S55PFI8

Memory IC Overview

The Renesas Electronics Corporation 7027S55PFI8 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-lead Thin Quad Flat Package (TQFP) measuring 14x14 mm.

Memory IC Feature Summary

• Dual-port architecture enabling independent simultaneous access for two processors or systems
• Asynchronous operation allowing flexible timing control without external clock synchronization
• Parallel data interface supporting standard high-speed memory bus connections

Memory IC Applications

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

Memory IC Procurement Notes

Verify the specific package variant and manufacturer documentation before procurement. Confirm that the 5V supply requirement aligns with system power rails. Check for RoHS compliance status and end-of-life notices, as older SRAM components may have limited availability or require alternative sourcing strategies for long-term production.

Memory IC Selection Notes

Select this component when dual independent access is required for a 512Kb memory space. Ensure the design accommodates the 5V logic level requirements rather than lower voltage standards. Consider the 55ns speed adequate for the target application's throughput needs. Verify that the 100-TQFP footprint fits the PCB 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 shared memory access without complex arbitration logic. The series typically offers various speed grades and package options to suit different performance and form factor requirements in networking and industrial equipment.

Memory IC Replacement Considerations

Check for direct pin-compatible upgrades within the same series. Verify if newer generations offer improved power consumption or RoHS compliance while maintaining the 512Kb capacity and 55ns speed.
