7207L25PDG8

Overview

The Renesas Electronics Corporation 7207L25PDG8 is an asynchronous FIFO memory IC with a storage capacity of 288K bits, organized as 32K words by 9 bits. It operates at a data rate of 28.5MHz with an access time of 25ns. The device supports unidirectional data transfer and functions within a supply voltage range of 4.5V to 5.5V. It is housed in a 28-PDIP package.

Feature Summary

• Asynchronous architecture enabling direct data transfer between independent clock domains
• Unidirectional data flow capability for buffer applications
• Standard TTL-compatible logic levels

Applications

• Interface buffering between microprocessors and peripheral devices
• Data acquisition systems requiring temporary storage
• Communication protocol conversion buffers

Procurement Notes

Verify component authenticity through authorized distributors due to potential counterfeit risks. Confirm RoHS compliance status as older variants may not meet current environmental standards. Check for obsolescence notices or lifecycle changes from the manufacturer before finalizing procurement plans.

Selection Notes

Select this component when unidirectional asynchronous buffering is required between mismatched clock domains. Ensure the 28-PDIP package fits the target PCB layout constraints. Verify that the 25ns access time meets system timing requirements for the specific application speed.

Part Context

This part belongs to the IDT 7207 series of asynchronous FIFOs. It shares architectural similarities with other members like the 7207L35J8 but differs in speed grade and package type. The series is designed for general-purpose buffering in digital logic circuits.

Replacement Considerations

Consider the 7207L35J8 for faster 35ns performance in PLCC packages. Evaluate the 7207L25PDG8-ND equivalent if sourcing through different distributors. Verify pin compatibility before substituting with other asynchronous FIFO families.
