71342LA35PF

Overview

The Renesas Electronics Corporation 71342LA35PF is a high-speed, asynchronous dual-port static random-access memory (SRAM) device. It features a storage capacity of 32 kbit organized as 4K words by 8 bits. The component provides an access time of 35 ns and operates within a supply voltage range of 4.5 V to 5.5 V. It utilizes a parallel interface and is housed in a 64-pin Thin Quad Flat Package (TQFP). The device supports surface-mount installation and includes internal semaphore logic for port arbitration.

Feature Summary

• Dual-port architecture with fully independent read/write ports
• Integrated semaphore logic block for inter-port arbitration
• Automatic power-down mode controlled by chip enable signals

Applications

• Interprocessor communication systems
• Master/Slave dual-port RAM configurations
• High-speed data buffering applications

Procurement Notes

Verify the specific package variant and lead-free status against current manufacturer documentation, as legacy components may have multiple revisions. Confirm moisture sensitivity level handling requirements prior to assembly. Check for official end-of-life notices or recommended replacement parts from Renesas Electronics to ensure long-term supply chain stability.

Selection Notes

Select this component when a 4Kx8 dual-port SRAM with 35 ns speed is required. Ensure the design accommodates the 64-pin TQFP footprint and 4.5V to 5.5V operating voltage. Verify that the application benefits from the integrated semaphore logic for simplified arbitration without external discrete gates.

Part Context

This part belongs to the 71342 series of dual-port SRAMs manufactured by Renesas Electronics. It is designed for standalone 8-bit operation or as a master unit paired with slave devices like the 71421 for wider data buses. The series emphasizes full-speed error-free operation through internal control logic.
