FT232RNQ-TRAY

Controllers Overview

The FT232RNQ-TRAY is a USB to UART bridge controller manufactured by Future Technology Devices International Ltd. It integrates a full USB protocol stack and an asynchronous serial interface on a single chip, eliminating the need for external firmware programming. The device features a fully integrated 1024-bit internal EEPROM for storing device descriptors and configuration data. It supports data transfer rates up to 3 Megabaud at TTL levels and includes 256-byte receive and 128-byte transmit buffers. The component is available in a 28-lead SSOP package and offers configurable CBUS I/O pins along with optional clock generator outputs.

Controllers Feature Summary

• Single-chip USB to asynchronous serial data transfer interface handling the entire USB protocol internally
• Integrated 1024-bit internal EEPROM for storing USB VID, PID, serial number, product description strings, and CBUS I/O configuration
• Configurable CBUS I/O pins providing additional functionality such as synchronous and asynchronous bit bang modes
• Optional clock generator output capability allowing the device to drive external microcontrollers or logic

Controllers Applications

• USB to serial UART interface designs requiring simplified hardware implementation
• Security dongle applications utilizing the FTDIChip-ID feature for software protection
• Embedded systems needing a compact USB-to-UART bridge with integrated memory

Controllers Procurement Notes

Verify the specific suffix 'NQ' against official FTDI documentation to confirm package type and tape-and-reel status. Ensure compatibility with required operating voltage levels and check for RoHS compliance markings on the component marking. Confirm that the pre-programmed unique USB serial number meets project identification requirements without manual reprogramming.

Controllers Selection Notes

Select this component when a complete USB-to-UART solution with integrated EEPROM is required to reduce external component count. Consider the FT232RNQ-TRAY for applications needing configurable CBUS pins for custom control signals or bit-bang operations. Evaluate the available clock output options if driving external logic is necessary. Verify that the 28-lead SSOP package fits the target PCB footprint constraints.

Controllers Part Context

The FT232R series represents a generation of USB UART controllers from FTDI that introduced integrated EEPROM and configurable CBUS pins compared to earlier models. This family simplifies design by handling the USB protocol entirely on-chip. The FT232RNQ-TRAY variant specifically denotes the packaging and reel format within this established product line, maintaining core functional compatibility with other FT232R derivatives.

Controllers Replacement Considerations

FT232RL serves as a direct functional equivalent within the same family. Other FTDI USB UART controllers may offer different pin counts or buffer sizes but require verification of EEPROM integration and CBUS availability.
