7027L35PFI

Memory IC Overview

The Renesas 7027L35PFI is a high-speed, asynchronous dual-port static random-access memory (SRAM) IC with a total storage capacity of 512 Kbit. The memory array is organized as 32K words by 16 bits. It features a maximum access time of 35 ns and operates within a supply voltage range of 4.5 V to 5.5 V. The device utilizes a parallel interface and is housed in a 100-TQFP surface-mount package with dimensions of 14x14 mm. It supports an industrial operating temperature range from -40°C to +85°C.

Memory IC Feature Summary

• Provides independent read/write ports for simultaneous data access without bus contention
• Supports asynchronous operation with fast 35 ns access times
• Designed for robust performance across extended industrial temperature ranges

Memory IC Applications

• High-speed data buffering in telecommunications equipment
• Cache memory implementation in embedded processing systems
• Data acquisition systems requiring concurrent port access

Memory IC Procurement Notes

Verify the specific suffix PFI against official Renesas documentation to confirm the 100-TQFP package and lead-free status. Confirm RoHS compliance and moisture sensitivity levels prior to assembly. Check for obsolescence notices or lifecycle changes directly from the manufacturer, as availability may vary. Ensure design-in compatibility with existing board layouts and power supplies.

Memory IC Selection Notes

Select this component when a 512 Kbit dual-port SRAM with 16-bit word width is required. The 35 ns speed class suits applications needing moderate-to-high throughput. Verify that the 4.5 V to 5.5 V supply voltage aligns with the system power architecture. Consider the 100-pin TQFP footprint for PCB layout constraints compared to other package options in the series.

Memory IC Part Context

This part belongs to the IDT 7027S/L family of dual-port SRAMs, now manufactured under the Renesas Electronics brand following corporate acquisitions. The 7027 series is engineered for applications demanding independent port access, distinguishing it from single-port memories. It serves as a legacy high-performance memory solution in industrial and communication sectors.

Memory IC Replacement Considerations

Cross-reference with IDT7027L35PFI for functional equivalence. Verify pinout and electrical specifications match exactly before substitution.
