72V2103L10PFI8

FIFOs Memory Overview

The 72V2103L10PFI8 is a synchronous FIFO memory device manufactured by Renesas Electronics. It features a storage capacity of 2.25 Mbit, organized as 128K x 18 bits or 256K x 9 bits. The component supports a maximum clock frequency of 100 MHz with an access time of 6.5 ns. It operates on a single 3.3 V power supply, with voltage limits ranging from 3.15 V to 3.45 V. The device is housed in an 80-TQFP package and supports unidirectional data flow.

FIFOs Memory Feature Summary

• Supports retransmit operation with fixed, low first word data latency time
• Features programmable Almost-Empty and Almost-Full flags for status signaling
• Includes auto power down functionality to minimize standby power consumption
• Allows independent read and write clocks for simultaneous operations

FIFOs Memory Applications

• Data buffering in high-speed communication systems
• Clock domain crossing interfaces
• Retransmit applications requiring low latency

FIFOs Memory Procurement Notes

This component is officially discontinued and no longer in production. Verification of availability should focus on surplus distributors or existing stock rather than direct manufacturer orders. Confirm RoHS compliance status and moisture sensitivity level prior to integration, as the part may have specific handling requirements due to its age and discontinuation status.

FIFOs Memory Selection Notes

Select this part only if legacy compatibility with the 72V2103 family is required. Verify that the 80-TQFP package fits the design constraints. Consider functional equivalents from current product lines if new designs are being developed, as this specific suffix variant may have limited long-term support options.

FIFOs Memory Part Context

The 72V2103L10PFI8 belongs to the SuperSync FIFO series, designed for low-power 3.3V applications. It is functionally compatible with older 5V devices like the 72291 but optimized for modern voltage levels. The 'L10' designation indicates specific timing characteristics within the 72V2103 lineup.

FIFOs Memory Replacement Considerations

Official substitutes include other variants within the 72V2103 series such as the 72V2103L10PFI. Cross-reference pinouts and electrical specifications carefully when considering alternative components.
