    SB030142024 – USB-UART BRIDGE SCHEMATIC BLOCK

      FT232RNL — USB FULL SPEED TO SERIAL UART IC

      SKU: SB030142024 Category:

      This schematic block features the FT232RNL, a highly integrated USB 2.0 Full‑Speed (12 Mbps) to serial UART bridge from FTDI. It handles the entire USB protocol on-chip and provides a reliable, transparent virtual com‑port interface. The IC also includes an internal oscillator and EEPROM, making it a compact, low-component solution for embedded USB‑to‑UART conversion.

      Housed in a 28‑pin SSOP package, this breakout-style module provides easy access to USB data lines, UART TX and RX, flow‑control signals, and configurable GPIO (CBUS) pins. Its dual-voltage I/O support (from 1.8 V up to 5 V) makes it compatible with a wide range of logic-level domains.

      Key Features:

      • USB 2.0 Full‑Speed (12 Mbps) slave interface
      • Up to 3 Mbaud UART data rate
      • Integrated oscillator and EEPROM for custom USB strings and configuration
      • Four configurable GPIO / CBUS pins
      • Hardware or software handshaking (XON/XOFF) supported
      • I/O voltage range: 1.8 V to 5 V
      • Virtual COM port support (no USB firmware required)
      • Operating temperature: –40 °C to +85 °C
      • 28-pin SSOP package, suitable for compact designs

      Typical Applications:

      • USB‑to-serial converters and debug cables
      • Embedded microcontroller USB interface (when MCU lacks USB)
      • Data-logging and telemetry systems
      • Consumer electronics with UART-based commands
      • Industrial control and instrumentation
      • Rapid prototyping of USB‑serial wearable or IoT devices

      By integrating this Quickboards schematic block, engineers can easily add USB connectivity to embedded systems, eliminate the need for external USB-serial modules, and rely on a proven, production-ready FTDI interface with robust driver support.
