7204L25TPI

Overview

The Renesas Electronics Corporation 7204L25TPI is an asynchronous FIFO memory device with a 36Kbit storage capacity organized as 4K words by 9 bits. It operates on a single 5.0V supply voltage within a range of 4.5V to 5.5V. The component features a unidirectional data interface and supports a maximum clock frequency of 28.5MHz, achieving a typical access time of 25ns. It is housed in a 28-pin Plastic Dual In-Line Package (PDIP) designed for through-hole mounting.

Feature Summary

• Asynchronous dual-port architecture enabling independent read and write clock domains
• Unidirectional data bus configuration for dedicated input/output signal flow
• CMOS technology ensuring low power consumption during operation
• Standard TTL-compatible I/O levels for broad system integration

Applications

• Data buffering between microprocessors and peripheral devices
• Clock domain crossing interfaces in mixed-signal systems
• High-speed serial-to-parallel conversion buffers
• Digital signal processing pipeline staging

Procurement Notes

Verify the specific suffix TPI confirms the PDIP package type and commercial temperature range against official datasheets. Confirm RoHS compliance status as legacy components may vary. Check for end-of-life notices or discontinuance notifications from Renesas prior to procurement planning. Ensure supplier documentation matches the exact part number to avoid pinout mismatches with similar SOIC variants.

Selection Notes

Select this component when a 25ns access speed and 4Kx9 organization are required for asynchronous buffering. The PDIP package is suitable for prototyping or applications requiring through-hole assembly. Compare against the 7204L15 series if faster 15ns performance is needed, or the 7204L50P if slower speeds suffice. Verify that the unidirectional interface meets the system's data flow requirements compared to bidirectional alternatives.

Part Context

This part belongs to the Renesas 7204L series of high-performance asynchronous FIFOs. These devices are designed for general-purpose memory buffering in industrial and commercial applications. The series offers various speed grades and package options to accommodate different timing and form factor constraints in embedded systems.

Replacement Considerations

The IDT7204L25TPI is a confirmed equivalent part number from Integrated Device Technology. Verify pin compatibility and electrical specifications before substitution.
