FT245RNQ-REEL

Controllers Overview

The FT245RNQ-REEL is a USB to parallel FIFO interface integrated circuit manufactured by FTDI. It operates within a supply voltage range of 1.8 V to 5.25 V and supports data rates up to 480 Mb/s in accordance with the USB 2.0 standard. The device features high-speed (HS) and full-speed (FS) capabilities, drawing a typical operating current of 15 mA. It is housed in a 32-VFQFN package with exposed pad, measuring 5x5 mm. The component functions as a bridge for USB to FIFO communication and is rated for an extended industrial operating temperature range from -40°C to +85°C.

Controllers Feature Summary

• Integrates complete USB protocol handling without requiring external firmware programming
• Includes on-chip 1024-bit EEPROM for storing device descriptors and FIFO configuration
• Features fully integrated clock generation eliminating the need for external crystals
• Provides configurable FIFO interface I/O pins supporting both synchronous and asynchronous modes

Controllers Applications

• Connecting MCU, PLD, or FPGA designs to USB interfaces
• Upgrading traditional peripherals to USB connectivity
• USB audio and low-bandwidth video data transmission
• USB smart card readers and industrial control systems

Controllers Procurement Notes

Verify component authenticity through authorized channels due to potential counterfeits. Confirm RoHS compliance status via official documentation before integration. Check for recent Product Change Notices regarding leadframe or specification updates. Ensure storage conditions account for moisture sensitivity levels specified in the datasheet to prevent package damage during reflow soldering processes.

Controllers Selection Notes

Select this model when a compact QFN footprint is required compared to SSOP alternatives. Verify that the 1.8V to 5.25V logic compatibility matches the target system voltage requirements. Consider the 32-pin density for PCB layout constraints. Evaluate if the integrated EEPROM and clock features sufficiently reduce external component count for the specific design architecture.

Controllers Part Context

This component belongs to the FT245R series, which serves as a bridge between USB hosts and parallel FIFO devices. It replaces older discrete USB controller solutions by integrating necessary passive components and memory directly onto the silicon die. The RNQ suffix specifically denotes the 32-pin QFN package variant, distinguishing it from the SSOP-based RL models within the same functional family.

Controllers Replacement Considerations

Public confirmed substitute part numbers include FT240XQ-R. Verify pinout compatibility and electrical specifications against the original design requirements before substitution. Review manufacturer Product Change Notices for any discontinuation notices affecting long-term availability.
