72V251L15PFI

FIFOs Memory Overview

The 72V251L15PFI is a synchronous FIFO memory device manufactured by Renesas Electronics. It features an 8K x 9 bit storage capacity, totaling 72K bits. The component operates with a data rate of 66.7MHz and has an access time of 10ns. It supports a supply voltage range of 3V to 3.6V and draws a maximum supply current of 20mA. The device utilizes a 32-TQFP (7x7) surface-mount package.

FIFOs Memory Feature Summary

• Synchronous operation with independent read and write clocks allowing simultaneous data transfer
• Programmable status flags including empty, full, half-full, almost-empty, and almost-full indicators
• Fixed low first word data latency for consistent timing performance
• Auto power down capability to minimize standby power consumption

FIFOs Memory Applications

• Buffering data streams in high-speed digital signal processing systems
• Interface bridging between components operating at different clock frequencies
• Data buffering in telecommunications equipment requiring low latency
• Memory staging in industrial control applications

FIFOs Memory Procurement Notes

This specific part number is officially discontinued and no longer in production. Verification of availability should focus on surplus distributors or secondary markets rather than direct manufacturer channels. Ensure that any sourced units are verified for authenticity and physical condition, as end-of-life products may have varying storage histories. Check for moisture sensitivity level compliance if the component has been stored outside controlled conditions.

FIFOs Memory Selection Notes

Engineers replacing this component must account for its discontinued status. While functionally compatible with other members of the 72V251 family, pin compatibility does not guarantee identical electrical characteristics across all variants. Verify that alternative sources meet the required 3V to 3.6V supply specifications and 10ns access time. Consider the 32-TQFP package constraints during redesign to ensure mechanical fit and thermal performance remain within acceptable limits for the target application.

FIFOs Memory Part Context

The 72V251L15PFI belongs to the Renesas 72V series of SuperSync FIFOs. This series is designed for 3.3V operation, offering lower power consumption compared to older 5V counterparts like the 72291. The device provides expandability in depth and width, making it suitable for various memory buffering needs. It shares functional similarities with the IDT72V21x1 series but offers larger capacity.

FIFOs Memory Replacement Considerations

Publicly confirmed substitute part numbers include IDT72V251L15PFI and 72V251L15PF. These alternatives maintain pin and functional compatibility. Verify that the specific suffix indicates the same package type and temperature grade before implementation.
