7203L25TPI

Overview

The Renesas Electronics Corporation 7203L25TPI is a CMOS parallel asynchronous FIFO memory device. It features a storage organization of 2K x 9 bits, providing a total capacity of 18.4 kbit. The component supports bidirectional data bus operations and operates within a supply voltage range of 4.5 V to 5.5 V. Key electrical specifications include a maximum access time of 25 ns and a maximum clock frequency of 28.5 MHz. The device is housed in a 28-pin PDIP package.

Feature Summary

• Asynchronous operation enabling independent read and write clocks for rate buffering between systems with varying speeds
• Bidirectional data bus architecture supporting flexible interface connections
• CMOS technology ensuring low power consumption relative to TTL equivalents

Applications

• Multiprocessing system data buffering
• Rate matching between asynchronous digital devices
• High-speed communication interface buffering

Procurement Notes

Verify the specific suffix TPI against official Renesas documentation to confirm package type and pinout compatibility. Confirm RoHS status as datasheets may indicate non-compliance for older revisions. Check for obsolescence notices or lifecycle status updates directly from the manufacturer before finalizing procurement plans.

Selection Notes

Select this component when a 2K x 9 depth with bidirectional I/O is required. Ensure the design accommodates the 25 ns access time and 28.5 MHz maximum frequency limits. Verify that the 28-pin PDIP package fits the target PCB layout constraints and thermal requirements.

Part Context

This part belongs to the 7203L series of asynchronous FIFOs manufactured by Renesas Electronics. The series typically offers various speed grades and packaging options. The 7203L25 variant specifically denotes the 25 ns speed grade within this family.

Replacement Considerations

Cross-reference with IDT7203L25TPI for potential functional equivalence. Verify pin compatibility and electrical parameters against any alternative sources.
