7203L25TP

Overview

The Renesas Electronics 7203L25TP is a CMOS asynchronous FIFO memory device organized as 2K x 9 bits, providing a total storage capacity of 18.4 kbit. It features a bidirectional data bus and supports a maximum clock frequency of 28.5 MHz with an access time of 25 ns. The component operates within a supply voltage range of 4.5 V to 5.5 V and includes one circuit. It is housed in a 28-pin PDIP package designed for through-hole mounting.

Feature Summary

• Asynchronous operation allows independent read and write clock domains without synchronization requirements.
• Bidirectional data bus architecture supports flexible data flow directions for system integration.
• CMOS technology ensures low power consumption and high noise immunity compared to older logic families.

Applications

• Data buffering between microprocessors and peripheral devices operating at different speeds
• Interface bridging in digital signal processing systems requiring temporary data storage
• Parallel data transfer applications in industrial control equipment

Procurement Notes

Verify component authenticity due to end-of-life status. Check for RoHS compliance variations across manufacturing lots. Confirm package integrity upon receipt as moisture sensitivity may affect solderability. Validate pin compatibility with existing PCB footprints before final assembly integration.

Selection Notes

Select this part when bidirectional data transfer is required with asynchronous timing. Ensure system voltage matches the 4.5V to 5.5V operational range. Consider the 25ns access time against system clock requirements. Verify that the 2Kx9 organization meets specific buffer depth needs for the application design.

Part Context

This component belongs to the 7203L series of CMOS asynchronous FIFOs manufactured by Renesas Electronics. The series offers various access times and organizations to suit different performance requirements. The 7203L25TP specifically provides a balance of speed and density for general-purpose parallel data buffering tasks in embedded systems.

Replacement Considerations

Publicly confirmed substitute part numbers include IDT7205L25TP. Verify electrical specifications and pinout compatibility before substitution. Note that alternative sources may have different packaging or qualification standards.
