7005L35PFI8

Overview

The Renesas Electronics Corporation 7005L35PFI8 is a dual-port static random-access memory (SRAM) integrated circuit. It provides a storage capacity of 64 kilobits, organized as 8K words by 8 bits. The device features an asynchronous parallel interface with a maximum access time of 35 nanoseconds. It operates within a supply voltage range of 4.5 volts to 5.5 volts and supports surface-mount installation in a 64-pin Thin Quad Flat Package (TQFP). The component is classified as single data rate (SDR) memory technology.

Feature Summary

• Dual-port architecture enabling independent simultaneous access from two distinct processors or systems
• Asynchronous operation allowing flexible timing integration without external clock synchronization requirements
• Parallel interface supporting standard digital logic connections for straightforward system integration

Applications

• Data buffering between high-speed processors and slower peripheral devices
• Cache memory implementation in embedded control systems
• Shared memory space for multi-processor communication architectures

Procurement Notes

Verify the exact suffix PFI8 against official datasheets to confirm package dimensions and pinout compatibility. Confirm RoHS compliance status as documentation indicates non-compliance. Check current lifecycle status as this part may be discontinued or subject to limited availability. Validate moisture sensitivity level handling requirements during assembly to prevent damage.

Selection Notes

Select this component when dual-port functionality is required for concurrent read-write operations. Ensure the 35 ns access speed meets the system timing constraints. Verify that the 64-TQFP package fits the available printed circuit board real estate. Confirm power supply stability within the specified voltage range to maintain data integrity.

Part Context

This component belongs to the Renesas 7005L series of dual-port SRAMs. It shares architectural similarities with other variants like the 7005L25 and 7005L35, differing primarily in access speed and package type. The series is designed for applications requiring high-speed data sharing between independent processing units.
