7203L12TPG

Overview

The Renesas 7203L12TPG is an asynchronous FIFO memory device featuring a 2 kbit storage capacity organized as 256 words by 9 bits. It supports bidirectional data transfer with a maximum clock frequency of 50 MHz and a typical access time of 12 ns. The component operates within a supply voltage range of 4.5 V to 5.5 V, drawing a maximum supply current of 80 mA. Designed for commercial temperature environments ranging from 0°C to +70°C, it is housed in a 28-pin PDIP package.

Feature Summary

• Asynchronous operation allows independent read and write clock domains for flexible interface integration.
• Bidirectional bus architecture supports versatile data routing configurations.
• Standard TTL-compatible logic levels ensure broad compatibility with existing digital systems.

Applications

• Data buffering between microprocessors and peripheral devices
• Interface bridging between components operating at different clock speeds
• Temporary data storage in high-speed digital signal processing chains

Procurement Notes

Verify the specific suffix 'TPG' against official Renesas documentation to confirm exact packaging and lead-free status. Confirm availability through authorized distributors as this component may be subject to discontinuation notices. Ensure the procurement channel provides valid traceability and authenticity guarantees for legacy semiconductor parts.

Selection Notes

Select this part when bidirectional data flow is required within an asynchronous FIFO application. The 9-bit width accommodates standard byte-oriented data with parity or error-checking bits. Verify that the 12 ns access time meets the system timing requirements and that the 5V supply voltage aligns with the target platform's power rails.

Part Context

This component belongs to the Renesas 7200L series of asynchronous FIFO memories. The series offers various access times and capacities to suit different performance needs. The 7203L12TPG specifically targets applications requiring moderate speed and bidirectional data handling capabilities within a standard industrial temperature range.

Replacement Considerations

Consult official Renesas substitution guides for verified equivalents. Generic cross-references may not match the bidirectional bus configuration or specific electrical characteristics. Verify pinout compatibility and functional equivalence before implementation.
