7133LA35PFI

Overview

The Renesas Electronics Corporation 7133LA35PFI is a dual-port static random-access memory (SRAM) integrated circuit. It features a storage capacity of 32 kilobits, organized as 2K words by 16 bits. The device utilizes an asynchronous parallel interface 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 100-pin Thin Quad Flat Package (TQFP) measuring 14x14 mm.

Feature Summary

• Supports simultaneous independent read/write operations at both Port A and Port B for high-throughput data handling.
• Provides asynchronous operation without requiring a system clock signal for basic memory access cycles.
• Enables flexible data bus configurations through dedicated byte write control inputs.

Applications

• High-speed digital signal processing systems requiring low-latency data buffering.
• Network communication equipment utilizing packet switching and routing logic.
• Industrial automation controllers managing real-time sensor data acquisition.

Procurement Notes

Verify the specific suffix 'PFI' against official manufacturer documentation to confirm pinout compatibility and package dimensions. Ensure that the selected component meets the required operating temperature specifications for the intended application environment. Cross-reference datasheet revisions to validate current manufacturing status and availability constraints before finalizing procurement plans.

Selection Notes

Select this component when dual-port architecture is necessary for concurrent processor access. Compare performance metrics against single-port alternatives if cost reduction is prioritized over bandwidth. Confirm that the 100-pin TQFP footprint aligns with existing printed circuit board layout constraints and thermal management requirements.
