7202LA12TPG

Overview

The Renesas Electronics Corporation 7202LA12TPG is an asynchronous FIFO memory device with a storage capacity of 9K bits, organized as 1K words by 9 bits. It features a unidirectional bus direction and supports a maximum clock frequency of 50 MHz with a typical access time of 12 ns. The component operates within a supply voltage range of 4.5 V to 5.5 V and draws a maximum supply current of 80 mA. Designed for industrial temperature ranges from 0°C to +70°C, it is housed in a 28-pin PDIP package.

Feature Summary

• Asynchronous operation for flexible data transfer between different clock domains
• Unidirectional data flow architecture supporting standard parallel interface protocols
• Retransmit capability allows for reliable data recovery during bus contention

Applications

• Buffering data streams in high-speed digital signal processing systems
• Interface bridging between microprocessors and peripheral devices operating at different speeds
• Data acquisition systems requiring temporary storage before batch processing

Procurement Notes

Verify the specific suffix 'TPG' against official Renesas documentation to confirm package type and tape/reel specifications, as suffixes often denote distinct packaging or environmental compliance variations. Confirm end-of-life status and availability through authorized distributors, as discontinuation notices may impact long-term supply stability. Ensure compatibility with existing PCB footprints for 28-pin DIP configurations.

Selection Notes

Select this component when unidirectional asynchronous buffering is required with 9-bit word width. Compare access times and power consumption against alternative FIFO families if lower latency or reduced current draw is critical. Verify that the 28-pin PDIP package fits the mechanical constraints of the target enclosure and assembly process.

Part Context

This part belongs to the Renesas 7202L series of CMOS parallel FIFOs, designed for general-purpose memory buffering applications. The series offers various speed grades and organization options to suit different system timing requirements. As a legacy component, it serves established designs requiring robust, simple asynchronous memory interfaces without complex control logic.

Replacement Considerations

Consult official substitution guides for equivalent parts such as the IDT7202LA12TPG, which shares functional compatibility. Verify pinout and electrical characteristics match before replacing to ensure system integrity.
