7205L25TPI

Overview

The Renesas Electronics Corporation 7205L25TPI is an asynchronous FIFO memory device with a storage capacity of 72 kbit, organized as 8k x 9. It features a unidirectional data bus and supports a maximum clock frequency of 28.5 MHz with a 25 ns access time. The component operates within a supply voltage range of 4.5 V to 5.5 V and draws a maximum power supply current of 120 mA. Designed for commercial use, it functions between 0°C and +70°C. The integrated circuit is housed in a 28-PDIP package.

Feature Summary

• Supports asynchronous read and write operations for independent clock domains
• Includes status flags to manage data flow and prevent overflow or underflow
• Provides retransmit capability for pointer reset functionality

Applications

• Multiprocessing systems requiring data buffering
• Rate matching applications between different speed components
• Interface bridging between disparate digital logic circuits

Procurement Notes

Verify the exact suffix configuration against official documentation, as variations exist within the 7205 series. Confirm RoHS compliance status, as some variants are non-compliant. Check lead-free availability if required by specific manufacturing standards. Ensure the supplier provides valid traceability for this obsolete component family.

Selection Notes

Select this part when a 72 kbit asynchronous FIFO with 9-bit width is required. Compare access times and package types against alternatives like the 7205L50P for slower speed needs. Verify that the 28-PDIP through-hole format matches the target PCB design constraints and thermal requirements.

Part Context

This component belongs to the 7205L25 series of high-speed CMOS FIFOs. It shares architectural similarities with other members of the 7200 family but offers specific timing characteristics suited for moderate-speed parallel data transfer applications. The device represents a legacy solution for buffer management in older industrial and computing hardware designs.

Replacement Considerations

Public confirmed substitute part numbers include IDT7205L25TP.
