FT230XS-R 概要
A USB-to-UART bridge is a class of interface ICs that converts USB 2.0 packets into asynchronous serial data, sitting within the broader hierarchy: USB bridge -> UART interface IC -> interface IC -> integrated circuit. These devices let a host PC talk to a microcontroller or another UART-based peripheral through a virtual COM port created by the chip's driver stack, removing the need for an external MCU-side USB stack.
Key features of the FT230XS-R include the complete FT-X series feature set, on-chip handling of the entire USB protocol, optimized pin count for compact PCB designs, configurable I/O drive strength, integrated power-on-reset, UART signal inversion option, internal 3.3V and 1.8V LDO regulators, low operating current of approximately 8 mA, USB suspend current of 125 uA, low USB bandwidth consumption, and UHCI/OHCI/EHCI host controller compatibility. Data rates from 300 baud to 3 Mbaud are supported.
Technically, the FT230X contains a USB 2.0 Full Speed (12 Mbps) Serial Interface Engine (SIE), a USB protocol controller, and a UART FIFO controller. FTDI's royalty-free Virtual COM Port (VCP) drivers and D2XX direct drivers are available for Windows, macOS, Linux, and Android, and each chip ships with a unique USB identifier pre-programmed in on-chip OTP memory that designers can customize for OEM branding.
Typical applications include USB-to-serial adapter cables, microcontroller programming and debug interfaces, industrial control panels, point-of-sale terminals, and embedded systems that need a quick USB connectivity upgrade over a legacy UART port. Its small SSOP-16 footprint suits space-constrained boards.
A key design consideration is that the FT230X is optimized for low pin count and therefore lacks the full modem-control signal set (RTS/CTS/DTR/DSR/RI) found on the larger FT232 series. Designs requiring complete hardware handshake lines should verify signal availability before committing to the optimized pin count.

主な用途
FT230XS-R の用途: 6 件s: USB-to-Serial Adapter Cable, Microcontroller Programming and Debug Interface, Industrial Control Panels, Point-of-Sale Terminals, Embedded System USB Connectivity Upgrade, USB Debug Port for FPGA Development Boards.
USB-to-Serial Adapter Cable
The FT230XS-R is the canonical choice for compact USB-to-UART adapter cables because it integrates the full USB 2.0 protocol stack on-chip, requiring no external firmware. Its 3 Mbaud ceiling and 8 mA operating current suit debug consoles for routers, set-top boxes, and Linux boards where the host exposes only a TTL UART header. The 16-pin SSOP footprint keeps the PCB under 10x20 mm, leaving room for an onboard 3.3V regulator and ESD protection diodes on D+/D-. Designers pair the chip with FTDI's royalty-free VCP drivers so the cable enumerates as a standard COM port on Windows, macOS, Linux, and Android with zero user configuration.
おすすめ
Microcontroller Programming and Debug Interface
The FT230XS-R is widely used as a USB-UART bridge for ISP programming of MCUs that lack native USB (e.g., ESP32 dev kits, STM32 Nucleo boards, ATmega328P Arduinos). The chip's CBUS-configurable GPIOs can be wired to the MCU's BOOT/RESET lines for automatic bootloader entry, while the on-chip 3.3V LDO supplies the target rail. Its 3 Mbaud ceiling compresses firmware-flash times compared with 115200 baud legacy bridges. Use the D2XX driver for direct bulk endpoint access when latency matters more than COM-port simplicity.
おすすめ
Industrial Control Panels
Industrial HMIs and PLC daughter-boards use the FT230XS-R to expose service ports over USB for field engineers, replacing legacy RS-232 DB-9 connectors. The -40C to +85C operating range tolerates factory-floor thermal swings, while 125 uA suspend current prevents battery-backed panels from draining their backup cells during storage. Internal 3.3V and 1.8V LDOs simplify BOM by eliminating an external regulator. Pair with opto-isolated USB transceivers if the panel is exposed to high common-mode voltage on the shop floor.
おすすめ
Point-of-Sale Terminals
POS terminals integrate the FT230XS-R to add USB diagnostics, peripheral enumeration, and receipt-printer ports over a virtual COM port. The chip's USB suspend current of 125 uA allows battery-powered mobile POS devices to meet Energy Star idle budgets, while the integrated ESD-protected D+/D- pins survive frequent cable insertions in retail environments. FTDI's D2XX API enables direct endpoint control for custom printer command sets. The OTP USB descriptor memory lets OEMs brand each terminal with a unique VID/PID without external EEPROM.
おすすめ
Embedded System USB Connectivity Upgrade
Designers upgrading legacy UART-only embedded designs to USB connectivity drop in the FT230XS-R for a single-chip solution that requires no firmware changes on the host MCU. The on-chip USB protocol handler, internal LDO regulators, and configurable CBUS GPIOs cover all control signals typically needed for legacy peripheral bridging. The SSOP-16 package replaces RS-232 level shifters in space-constrained wearables and IoT sensor hubs, where PCB area and BOM count drive cost. Linux 3.2+ and Android driver support ensure compatibility with embedded Linux SoCs.
おすすめ
USB Debug Port for FPGA Development Boards
FPGA development boards use the FT230XS-R to expose JTAG-over-UART or soft-processor console output to a host PC. The 3 Mbaud UART ceiling keeps printf-style debug latency low enough for real-time signal-processing visualization on the host, while the integrated LDO regulators power both the chip and a small auxiliary rail for level translation. Hardware designers route the FT230XS-R's CBUS pins to the FPGA's JTAG TDI/TDO for combined debug + programming over a single USB cable, simplifying board bring-up. D2XX direct driver access enables bit-banged SPI/I2C for slow-speed peripheral configuration during prototyping.

設計ノート
Route the USB D+ and D- traces as a 90-ohm differential pair with matched length within 150 mil. Place the FT230XS-R's 27 ohm series termination resistors on D+ and D- within 4 mm of the chip's DP/DM pins to meet USB 2.0 Full Speed signal-integrity requirements. A common-mode choke on D+/D- improves ESD immunity in industrial enclosures.
The FT230XS-R includes internal 3.3 V and 1.8 V LDOs that power the USB transceiver and internal logic. Decouple VCC with a 4.7 uF X5R ceramic capacitor placed within 2 mm of the VCC pin. The VCCIO pin sets the UART logic level (1.8 V to VCC) and must be decoupled with a 100 nF ceramic if left floating to its internal regulator output.
Do not tie the TEST pin (pin 16) to logic high; it must remain floating or tied to GND per the FT230X datasheet to avoid latching the part into test mode. Forgetting to populate the 12 kHz clock reference on the XIN/XOUT pins (when not using the internal oscillator) is another frequent layout mistake. The 125 uA USB suspend current is only achieved if the host actively suspends the USB bus; otherwise current remains at 8 mA.
Place the FT230XS-R's CBUS-configurable GPIO traces away from switching power supply nodes to avoid crosstalk into the USB data lines. If the board uses an external 12 MHz crystal instead of the internal oscillator, place the crystal within 5 mm of the chip and guard it with a ground pour to minimize EMI. Keep the reset (RST) trace short and away from high-current switching nodes.
