7006L35PFI8

Overview

The 7006L35PFI8 is an asynchronous dual-port static random-access memory (SRAM) manufactured by Renesas Electronics Corporation. It provides a total storage capacity of 128 kilobits, organized as 16K words by 8 bits. The device features parallel interface access with a maximum access time of 35 nanoseconds. It operates within a supply voltage range of 4.5V to 5.5V and supports surface-mount installation in a 64-pin Thin Quad Flat Package measuring 14x14 millimeters.

Feature Summary

• Supports simultaneous independent access from two distinct ports for concurrent read/write operations
• Utilizes asynchronous control logic without requiring a system clock signal
• Employs standard parallel data bus architecture for straightforward integration

Applications

• High-speed data buffering in telecommunications equipment
• Cache memory implementation in embedded processing systems
• Data logging applications in industrial automation controllers

Procurement Notes

Verify the specific suffix PFI8 against official Renesas documentation to confirm package dimensions and tape-and-reel specifications. Ensure compatibility with 5V logic levels and check for moisture sensitivity classification prior to soldering. Confirm end-of-life status or obsolescence notices through authorized distributors before finalizing procurement plans.

Selection Notes

Select this component when dual-port functionality is required for separate master-slave architectures. The 35ns speed suits moderate-frequency asynchronous buses. Verify that the 64-TQFP footprint fits the target PCB layout constraints. Consider thermal dissipation requirements given the parallel interface power characteristics at 5V operation.

Part Context

This part belongs to the Renesas 7006 series of dual-port SRAMs. It shares architectural similarities with other members like the 7006L15 and 7006L20, differing primarily in access speed and operating temperature ranges. The series targets applications needing non-volatile-like persistence during power cycles but requires constant power for data retention.
