7027L20PF

Memory IC Overview

The 7027L20PF is a dual-port asynchronous static random-access memory (SRAM) integrated circuit manufactured by Renesas Electronics. It provides a total storage capacity of 512 kilobits, organized as 32K words by 16 bits. The device features a parallel interface with a maximum access time of 20 nanoseconds. It operates within a supply voltage range of 4.5V to 5.5V and supports surface-mount installation in a 100-pin TQFP package measuring 14x14 mm. The component is designed for commercial temperature operation between 0°C and 70°C.

Memory IC Feature Summary

• Supports simultaneous independent read/write operations at two distinct ports
• Provides fast asynchronous data transfer via parallel interface
• Maintains volatile data storage without requiring continuous power refresh cycles

Memory IC Applications

• High-speed data buffering in telecommunications equipment
• Cache memory implementation in industrial control systems
• Data logging applications in automotive electronics

Memory IC Procurement Notes

Verify the specific suffix designation against official Renesas documentation to confirm package type and environmental compliance status. Confirm current production lifecycle status, as availability may be limited. Ensure compatibility with existing board layouts regarding pin assignments and thermal requirements before procurement.

Memory IC Selection Notes

Select this component when dual-port functionality is required for concurrent processor access. Verify that the 5V logic levels match system requirements. Consider the 100-pin footprint constraints during PCB design. Evaluate alternative speeds if faster cycle times are necessary for the target application.

Memory IC Part Context

This part belongs to the 7027L series of dual-port SRAMs from Renesas. The series offers various speed grades and organization options. The 7027L20 variant specifically targets applications needing moderate speed with standard 5V operation. It serves as a bridge between high-speed CPU caches and slower serial memories.

Memory IC Replacement Considerations

Check for direct cross-reference part numbers such as IDT7027L20PF. Verify pin-to-pin compatibility and electrical parameter equivalence before substitution.
