7005L35PF

Overview

The Renesas Electronics Corporation 7005L35PF is a dual-port static random-access memory (SRAM) integrated circuit. It features a storage capacity of 64 kilobits organized as 8K words by 8 bits. The device utilizes an asynchronous parallel interface with a maximum access time and write cycle time of 35 nanoseconds. It operates within a supply voltage range of 4.5 volts to 5.5 volts. The component is housed in a 64-lead Thin Quad Flat Package (TQFP) with dimensions of 14x14 millimeters, designed for surface-mount installation. The operational temperature range extends from 0°C to 70°C.

Feature Summary

• Provides independent read/write ports for simultaneous data access without bus contention
• Supports asynchronous operation with fast 35 nanosecond access times
• Compatible with standard 5-volt logic families for direct interfacing

Applications

• High-speed data buffering in communication systems
• Cache memory implementation in embedded processors
• FIFO buffer applications in industrial control equipment

Procurement Notes

Verify the specific suffix requirements when sourcing replacements, as package variations exist within the product family. Confirm that the replacement component matches the original 5-volt operating specifications and pinout compatibility. Check for RoHS compliance status if environmental regulations apply to the final assembly. Ensure the substitute part supports the required 35 nanosecond performance metrics for the target application timing constraints.

Selection Notes

Select this component for designs requiring independent dual-port memory access at 5-volt logic levels. The 64-kilobit capacity suits moderate data buffering needs. Consider the TQFP package for surface-mount assembly processes. Evaluate thermal management requirements within the commercial temperature range. Verify that the parallel interface aligns with the system controller capabilities.

Part Context

This part belongs to the 7005L series of dual-port SRAMs manufactured by Renesas Electronics. The series offers various speed grades and capacities for different memory density requirements. The 7005L35 variant specifically targets 35-nanosecond performance applications. The PF suffix denotes the 64-lead TQFP surface-mount package configuration used in compact electronic assemblies.

Replacement Considerations

The 70V05L15PFG is listed as an upgrade alternative. Verify voltage compatibility as the 70V series typically operates at 3.3 volts rather than 5 volts. Ensure the replacement package matches the existing footprint or design a new PCB layout accordingly.
