7202LA12J

Overview

The Renesas Electronics Corporation 7202LA12J is an asynchronous FIFO memory integrated circuit belonging to the 7200 series. It provides a storage capacity of 9K bits, organized as 1K words by 9 bits. The device supports unidirectional data transfer with a maximum data rate of 50MHz and features a typical access time of 12ns. It operates within a supply voltage range of 4.5V to 5.5V and draws a maximum supply current of 80mA. The component is housed in a 32-PLCC package with J-leads, suitable for surface mount installation, and functions reliably across an operating temperature range of 0°C to 70°C.

Feature Summary

• Asynchronous operation allows independent read and write clock domains for flexible interface integration.
• Retransmit capability enables data preservation during bus contention or system errors.
• CMOS parallel architecture ensures low power consumption and high-speed data throughput.

Applications

• Buffering data streams between microprocessors and peripheral devices
• Synchronizing data transfers in communication interfaces
• Temporary storage in digital signal processing pipelines

Procurement Notes

Verify component authenticity through authorized distributors due to discontinued status. Confirm RoHS compliance requirements as original units may not meet current environmental standards. Check for direct replacements like the 7202LA12JG which offers updated manufacturing specifications. Validate package integrity upon receipt to ensure pin compatibility with existing PCB footprints.

Selection Notes

Consider the 7202LA12JG as a primary alternative for new designs requiring equivalent performance with modern compliance. Evaluate board space constraints as both variants utilize the 32-PLCC package. Assess thermal management needs given the 80mA maximum current draw. Ensure voltage levels match the 4.5V to 5.5V operational range of the target system.

Part Context

This component is part of the Renesas 7200 series of asynchronous FIFOs, designed for high-performance buffering applications. The series includes various speed grades and configurations to suit different system requirements. As a legacy product, it represents established CMOS technology widely used in industrial and commercial electronics before newer generations were introduced.

Replacement Considerations

The 7202LA12JG is a confirmed direct replacement offering identical electrical characteristics and pinout compatibility. It maintains the same 32-PLCC package and functional specifications while adhering to updated manufacturing standards.
