7034L20PFI

Memory IC Overview

The 7034L20PFI is an asynchronous dual-port static random-access memory (SRAM) manufactured by Renesas Electronics. It provides a storage capacity of 72 kbit, organized as 4K words by 18 bits. The device features a parallel interface with a maximum access time of 20 ns. It operates within a supply voltage range of 3.0 V to 3.6 V and supports surface-mount installation in a TQFP-100 package. The component is rated for industrial temperature operation from -40°C to +85°C.

Memory IC Feature Summary

• Dual-port architecture enabling independent simultaneous access to the same memory array
• Asynchronous operation compatible with standard parallel bus interfaces
• Industrial-grade thermal stability for reliable performance in demanding environments

Memory IC Applications

• High-speed data buffering in telecommunications equipment
• Cache memory implementation in embedded processing systems
• Data logging applications requiring rapid write cycles

Memory IC Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to potential availability constraints. Confirm RoHS compliance status and specific manufacturing date codes prior to procurement. Ensure proper handling procedures are followed given humidity sensitivity classifications associated with this package type.

Memory IC Selection Notes

Select this component when independent read/write ports are required for concurrent data operations. The 18-bit word width suits applications needing parity or error correction bits integrated into the data path. Verify that the 20 ns access speed meets system timing requirements and that the TQFP-100 footprint aligns with PCB layout constraints.

Memory IC Part Context

This part belongs to the 70V35/7034 series of low-power dual-port SRAMs. It shares architectural similarities with other members like the 70V35L20PFI but differs in organization and capacity. The series is designed for high-performance memory applications requiring non-volatile-like speed without the complexity of flash technology.

Memory IC Replacement Considerations

Cross-reference with IDT7034L20PFI for functional equivalence. Verify pin compatibility and electrical specifications before substitution. Ensure the replacement source guarantees identical package dimensions and lead finish.
