Product details
Overview
CY7C65223-24LQXSXQLA1 from Infineon is a single-channel USB 2.0 Full-Speed (12 Mbps) to UART bridge controller with integrated 48 MHz oscillator, 4 GPIOs, 512-byte flash for configuration storage, and support for RS232/RS422/RS485 physical layer interfacing. It operates from 1.71 V to 5.5 V and delivers up to 3 Mbps UART data rate in industrial temperature range (–40°C to +85°C), used in medical devices and POS terminals requiring stable COM port enumeration.
For engineers reviewing the CY7C65223-24LQXSXQLA1 datasheet, CY7C65223-24LQXSXQLA1 pinout, CY7C65223-24LQXSXQLA1 application, or CY7C65223-24LQXSXQLA1 equivalent, key selection criteria include CDC-class USB enumeration stability, software/hardware flow control flexibility, UART pin count configurability (2/4/6/8-pin), BCD v1.2 peripheral detection, and QFN-24 package compatibility with automated PCB assembly.
Technical Context
The device implements a full USB 2.0-compliant Serial Interface Engine (SIE) with integrated USB transceiver, termination resistors, and battery charger detection logic compliant with USB BC 1.2 (peripheral-only mode). Its UART block supports programmable data formats (7–8 bits, 1–2 stop bits, five parity modes) and error detection (parity, framing, overrun).
Internal clocking uses a factory-trimmed 48 MHz oscillator for USB timing and a 32 kHz oscillator for low-power suspend/resume operations. Configuration is stored in nonvolatile 512-byte flash memory and applied at power-up, enabling fixed COM port assignment and vendor descriptor customization without firmware development.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| USB Speed | Full-Speed (12 Mbps); enables CDC-class enumeration on all major OS without custom drivers. |
| UART Max Data Rate | 3 Mbps; supports high-throughput serial protocols like Modbus RTU over RS485 without bottleneck. |
| FIFO Depth | 190 bytes TX/RX; reduces host CPU interrupt load and prevents data loss during burst transfers. |
| GPIO Count | 4 pins; configurable as general-purpose I/O or UART control signals (RTS/CTS/DTR/DSR) depending on interface mode. |
| Operating Voltage | 1.71 V to 5.5 V; allows direct connection to 3.3 V or 5 V logic domains without level-shifting circuitry. |
| Temperature Range | –40°C to +85°C (industrial grade); qualified for use in factory automation and outdoor kiosk environments. |
| ESD Rating | 2.2 kV HBM; provides robustness against handling-induced discharge during board assembly and field service. |
Pinout & Package
Package: 24-pin QFN (4.0 mm × 4.0 mm, 0.5 mm pitch, 0.55 mm height), RoHS-compliant, exposed thermal pad.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDDD | Digital supply voltage | Core logic and USB PHY power rail; must be decoupled with 100 nF capacitor near pin. |
| VCCD | I/O supply voltage | Configurable 1.71–5.5 V rail for UART/GPIO voltage level setting; independent of VDDD. |
| USBDP / USBDM | USB differential data pair | Integrated 1.5 kΩ pull-up on USBDP enables Full-Speed device enumeration; no external resistors required. |
| RxD / TxD | UART receive/transmit | Default 2-pin UART interface; additional pins (RTS#, CTS#, DTR#, DSR#) enabled via flash configuration. |
| nXRES | Active-low reset input | Asynchronous reset signal; internal pull-up ensures reliable startup without external RC network. |
| VBUS | USB bus voltage sense | Detects USB host presence; enables automatic switch between bus-powered and self-powered operation modes. |
Key Features
| Feature | Design Value |
|---|---|
| Fixed COM port assignment | Unique serial number per device ensures consistent Windows/Linux COM port enumeration across reboots and USB port swaps. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar USB-to-serial bridge applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY7C65223D-24LQXST | Dual-channel UART; same 4-GPIO count but supports two independent serial interfaces. | Required when bridging two legacy serial peripherals (e.g., barcode scanner + receipt printer) simultaneously. | Select only if dual-channel functionality is mandatory; otherwise, CY7C65223 offers lower cost and smaller footprint. |
| CY7C65213A-32LTXIT | 32-pin QFN; 8 GPIOs; supports RS485 hardware direction control and I²C master mode. | Better suited for systems needing I²C sensor integration alongside UART, or requiring more GPIOs for status LEDs/switches. | Choose when expanding beyond pure UART bridging-e.g., adding local sensor monitoring without MCU involvement. |
Compared with CY7C65223D and CY7C65213A, the CY7C65223-24LQXSXQLA1 delivers optimal balance of compact QFN-24 packaging, industrial temperature rating, and single-channel performance-ideal for cost-sensitive, space-constrained USB connectivity upgrades where dual interfaces or I²C are unnecessary.

FAQ
Does CY7C65223-24LQXSXQLA1 require an external crystal?
No. The device integrates a factory-trimmed 48 MHz oscillator sufficient for USB Full-Speed timing compliance. External crystals are not supported or required, simplifying layout and reducing BOM count by one passive component and two load capacitors.
Can the UART interface be configured for RS485 half-duplex operation?
Yes. Using two GPIO pins configured as DE (driver enable) and RE (receiver enable), the CY7C65223 supports RS485 half-duplex mode. The 4-GPIO count allows simultaneous UART signal routing and transceiver control without external logic, verified in Infineon Application Note AN91445.
Is Windows 11 driver support included?
Yes. The device uses standard USB CDC class drivers built into Windows 11 (x64/x86), requiring no additional INF installation. COM port enumeration behavior-including persistent numbering-is identical to Windows 10 due to shared underlying driver architecture and unique serial number binding.
What is the maximum sustained UART data rate under continuous transmission?
The device sustains 3 Mbps UART data rate with no packet loss when using 190-byte FIFOs and hardware flow control (RTS/CTS). At this rate, transmit buffer empty interrupts occur every ~500 µs, enabling efficient polling or DMA-based host-side buffering in Linux or Windows kernel-mode drivers.
