72V3640L15PFI

FIFOs Memory Overview

The 72V3640L15PFI is a synchronous FIFO manufactured by Renesas Electronics Corporation, belonging to the 72V series. It features a storage capacity of 36K bits organized as 1K x 36. The device supports unidirectional data transfer with a maximum clock frequency of 66.7MHz and an access time of 10ns. It operates on a single 3.3V power supply within a voltage range of 3.15V to 3.45V, drawing a maximum supply current of 40mA. The component is housed in a 128-pin TQFP package measuring 14x20mm and is rated for industrial operating temperatures from -40°C to +85°C.

FIFOs Memory Feature Summary

• Supports First Word Fall Through (FWFT) timing mode for reduced latency
• Includes programmable Almost-Full and Almost-Empty flags for buffer management
• Features retransmit capability allowing read pointer reset

FIFOs Memory Applications

• Multiprocessing systems requiring rate buffering
• Data acquisition interfaces
• High-speed digital signal processing pipelines

FIFOs Memory Procurement Notes

Verify RoHS compliance status carefully, as documentation indicates non-compliance. Confirm package dimensions against design constraints due to potential suffix variations. Check for End-of-Life notices or product discontinuance notifications prior to finalizing procurement plans.

FIFOs Memory Selection Notes

Select this component when a unidirectional synchronous FIFO with 36-bit width is required. Ensure system voltage aligns with the 3.3V specification. Verify that the 128-pin TQFP footprint matches the PCB layout requirements.

FIFOs Memory Part Context

This part belongs to the IDT/Renesas 72V3640 family of high-performance synchronous FIFOs. These devices are designed for applications demanding fast data throughput and reliable buffering between asynchronous or synchronous domains. The 72V3640 variant specifically offers 1K x 36 organization.

FIFOs Memory Replacement Considerations

Consult official datasheets for direct pin-compatible substitutes within the 72V36xx series. Verify electrical characteristics and package compatibility before substitution.
