72V2101L15PF8

FIFOs Memory Overview

The 72V2101L15PF8 is a synchronous FIFO memory device manufactured by Renesas Electronics Corporation. It features a storage capacity of 2.25M bits, organized as 256K words by 9 bits. The component supports unidirectional data transfer with a maximum data rate of 66.7MHz and an access time of 10ns. It operates within a supply voltage range of 3.15 V to 3.45 V and has a maximum supply current of 55mA. The device is housed in a 64-TQFP (14x14) surface-mount package.

FIFOs Memory Feature Summary

• Supports First Word Fall Through (FWFT) operation for fixed, low first word data latency.
• Includes programmable Almost-Empty and Almost-Full flags for precise status monitoring.
• Enables retransmit operations with independent read and write clock domains.

FIFOs Memory Applications

• Data buffering in graphics processing systems
• Interprocessor communication interfaces
• Local area network data handling

FIFOs Memory Procurement Notes

Verify the specific suffix 'PFI8' against official Renesas documentation to confirm pinout and packaging details, as distributor listings may vary. Confirm RoHS compliance status, as some sources indicate non-compliance for this part number. Check for active obsolescence notices or Product Change Notifications (PCNs) prior to procurement to ensure long-term availability and manufacturing continuity.

FIFOs Memory Selection Notes

Select this component when a 256K x 9 synchronous FIFO with 10ns access time is required. Ensure the system design accommodates the 3.15 V to 3.45 V supply voltage range. Verify that the 64-TQFP package dimensions fit the target PCB layout. Consider the 55mA maximum supply current for power budget calculations and thermal management requirements during high-speed operation at 66.7MHz.

FIFOs Memory Part Context

This device belongs to the 72V series of SuperSync FIFO memories from Renesas Electronics. It is functionally compatible with previous generations such as the IDT72V21x1 family. The 72V2101 variant specifically provides 256K x 9 depth, distinguishing it from other members like the 72V215 which offers different memory organizations within the same high-performance synchronous interface standard.

FIFOs Memory Replacement Considerations

The 72V2101L15PFGI is a lead-free alternative within the same functional specification. Cross-reference with the IDT72V2101L15PFI8 alias to verify compatibility with existing designs using Integrated Device Technology branding.
