VNC2-32Q1C-TRAY

Controllers Overview

The VNC2-32Q1C-TRAY is a USB interface integrated circuit from the Vinculum-II series, manufactured by FTDI. It functions as a dual USB host controller supporting USB 2.0 High Speed (480 Mb/s) and Full Speed (12 Mb/s) protocols. The device integrates a customized 16-bit MCU core with 256 KByte e-Flash program memory and 16 KByte SRAM data memory. It features two independent USB transceivers and supports SPI and UART interfaces for host communication. Operating voltage ranges from 1.62 V to 1.98 V, with a typical supply current of 25 mA. The component is housed in a 32-pin QFN package measuring 7 x 7 mm with a height of 0.85 mm, suitable for surface mount installation.

Controllers Feature Summary

• Integrates a user-programmable 16-bit MCU core with embedded non-volatile memory for custom application firmware implementation.
• Provides dual USB 2.0 host connectivity with independent transceivers for simultaneous peripheral management.
• Supports standard communication interfaces including SPI and UART for system integration.

Controllers Applications

• Embedded USB 2.0 host designs requiring custom application logic
• Development of portable devices with USB peripheral connectivity
• Industrial control systems utilizing USB-based data acquisition

Controllers Procurement Notes

Verify the specific suffix 'TRAY' indicates tray packaging when ordering, distinct from reel or cut tape variants. Confirm RoHS compliance status through official manufacturer documentation prior to procurement. Ensure moisture sensitivity level (MSL 3) handling requirements are met during storage and assembly processes to maintain component integrity.

Controllers Selection Notes

Select this model for applications requiring a standalone USB host controller with embedded processing capabilities. Compare pin count and package dimensions against board layout constraints, noting the 32-QFN form factor. Evaluate memory requirements against the available 256 KByte e-Flash and 16 KByte SRAM to ensure sufficient space for custom firmware execution without external memory dependencies.

Controllers Part Context

This component belongs to the Vinculum-II family, designed to simplify USB connectivity in embedded systems. Unlike simple protocol converters, it offers full programmability via an onboard MCU core. The 32-pin variant provides a compact solution for dual-host applications, distinguishing it from larger packages like the 48-pin version while maintaining core functionality.

Controllers Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Designers should consult official FTDI documentation for cross-reference information or evaluate alternative controllers within the same product family based on pin compatibility and functional requirements.
