72421L25PFI8

FIFOs Memory Overview

The Renesas Electronics Corporation 72421L25PFI8 is a synchronous FIFO memory device with a storage capacity of 576 bits, organized as 64 words by 9 bits. It features a maximum access time of 15 nanoseconds and operates at a clock frequency up to 40 MHz. The component supports a supply voltage range of 4.5 V to 5.5 V and functions within an operating temperature range of 0°C to 70°C. It is housed in a 32-pin TQFP package.

FIFOs Memory Feature Summary

• Synchronous FIFO architecture for data buffering
• CMOS technology implementation
• Parallel interface connectivity

FIFOs Memory Applications

• Data buffering in digital signal processing systems
• Interface bridging between asynchronous logic blocks
• Temporary storage in high-speed communication protocols

FIFOs Memory Procurement Notes

Verify the specific suffix '8' against official Renesas documentation to confirm pinout or electrical variations compared to standard variants. Confirm RoHS compliance status as historical records indicate non-compliance for similar IDT-branded units. Check current lifecycle status as this part may be discontinued or subject to last-time buy restrictions.

FIFOs Memory Selection Notes

Select this component when a compact synchronous FIFO solution is required for 9-bit wide data paths. Ensure the system power supply strictly adheres to the 4.5 V to 5.5 V range. Verify that the 32-pin TQFP package fits the PCB layout constraints and that the 0°C to 70°C commercial temperature range meets environmental requirements.

FIFOs Memory Part Context

This device belongs to the IDT 72421 series of synchronous FIFOs, now manufactured under the Renesas Electronics brand following corporate acquisitions. It serves as a direct replacement for legacy Integrated Device Technology components in existing designs requiring reliable, low-latency data storage for parallel bus architectures.

FIFOs Memory Replacement Considerations

The IDT72421L25PFI is a documented alias for this component. Verify pin compatibility and electrical specifications before substituting with other 64x9 synchronous FIFOs from different manufacturers.
