71342LA20PF

Memory IC Overview

The Renesas Electronics Corporation 71342LA20PF is a dual-port static random-access memory (SRAM) device. It features a storage capacity of 32 kilobits, organized as 4K words by 8 bits. The component supports parallel interface communication with an access time of 20 nanoseconds and a write cycle time of 20 nanoseconds. It operates on a single 5-volt power supply ranging from 4.5 to 5.5 volts. The device is housed in a 64-lead thin quad flatpack package designed for surface mount technology.

Memory IC Feature Summary

• Dual-port architecture enabling simultaneous independent access to the same memory location from two separate ports without hardware arbitration.
• Asynchronous operation allowing flexible timing control for both read and write cycles across either port.
• Automatic power-down functionality controlled by chip enable signals to minimize standby power consumption.

Memory IC Applications

• High-speed data buffering in telecommunications equipment
• Cache memory implementation in embedded processing systems
• Data storage in industrial automation controllers

Memory IC Procurement Notes

Verify the exact suffix configuration against official documentation, as variations such as PFGI may indicate specific temperature grades or packaging formats. Confirm RoHS compliance status and moisture sensitivity levels prior to integration. Check current production status as this series may be subject to obsolescence notices. Ensure compatibility with existing board layouts regarding pin assignments and voltage requirements.

Memory IC Selection Notes

Select this component when dual-port capability is required for concurrent data exchange between processors. The 20-nanosecond speed suits applications demanding low-latency memory access. Verify that the 64-lead TQFP package fits the available footprint. Consider thermal management requirements given the maximum operating temperature limits and power dissipation characteristics during active use.

Memory IC Part Context

This part belongs to the Renesas 71342SA/LA family of dual-port SRAMs. These devices are engineered for systems requiring contention handling or external arbitration mechanisms. The family provides scalable memory solutions with varying access speeds and package options to accommodate different performance and physical constraints in electronic designs.

Memory IC Replacement Considerations

Official substitutes include the 71342LA25PFGI, which offers similar specifications with potential differences in speed grade or packaging. Verify pin-to-pin compatibility and electrical parameters before substitution. Consult manufacturer obsolescence notices for end-of-life guidance.
