7027L20PFI8

Memory IC Overview

The Renesas Electronics Corporation 7027L20PFI8 is a dual-port 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 asynchronous parallel interface operation with a maximum access time of 20 nanoseconds. It operates within a supply voltage range of 4.5 volts to 5.5 volts. The component is housed in a 100-pin Thin Quad Flat Package (TQFP) with dimensions of 14x14 millimeters, designed for surface-mount technology applications.

Memory IC Feature Summary

• Dual-port architecture enabling independent simultaneous access from two distinct processors or systems
• Asynchronous parallel interface supporting standard logic levels for flexible system integration
• High-speed data retrieval capability with 20 nanosecond access time specification

Memory IC Applications

• Network equipment buffer memory management
• Industrial control system data logging and processing
• Telecommunications signal processing hardware

Memory IC Procurement Notes

Verify the specific suffix PFI8 against official Renesas documentation to confirm pinout compatibility and package dimensions. Confirm RoHS compliance status as sources indicate non-compliance. Check current lifecycle status as the part may be discontinued or subject to limited availability constraints before initiating procurement processes.

Memory IC Selection Notes

Select this component when dual-port functionality is required for shared memory access between multiple masters. Ensure the system design supports 5V logic levels and accommodates the 100-pin TQFP footprint. Verify that the 20 ns access speed meets the timing requirements of the target application without requiring faster alternatives.

Memory IC Part Context

This device belongs to the Renesas 7027L20 series of dual-port SRAMs. It shares architectural similarities with other members of the family but differs in specific organization and speed grades. The 7027L20PFI8 variant specifically denotes the 512Kb density with 20 ns performance in the TQFP-100 package configuration.
