Product details
Overview
CY7C65223-24LQXSTXUMA1 from Infineon is a single-channel USB 2.0 Full-Speed (12 Mbps) to UART bridge controller supporting CDC, PHDC, and vendor-class USB protocols, with integrated 48 MHz oscillator, 4 GPIOs, and configurable 2-/4-/6-/8-pin UART interface up to 3 Mbps data rate-used in medical devices, POS terminals, and industrial test equipment.
For engineers reviewing the CY7C65223-24LQXSTXUMA1 datasheet, CY7C65223-24LQXSTXUMA1 pinout, CY7C65223-24LQXSTXUMA1 application, or CY7C65223-24LQXSTXUMA1 equivalent, key selection factors include UART pin count flexibility, BCD v1.2 peripheral detection support, RS232/422/485 interface compatibility, 512-byte flash configuration storage, and Windows/Linux/Mac OS driver availability across legacy and modern OS versions.
Technical Context
The device implements a USB Serial Interface Engine (SIE) compliant with USB 2.0 Full-Speed, featuring integrated USB termination resistors and battery charger detection logic per USB BC 1.2 (peripheral-only mode). It embeds dual oscillators: a 48 MHz master clock for USB timing and a 32 kHz auxiliary clock for low-power suspend/resume operations.
UART functionality includes 256-byte TX/RX FIFOs, software and hardware flow control (CTS/RTS), parity/framing/error detection, and configurable data format (7–8 bits, 1–2 stop bits, five parity modes). The serial interface supports RS232/RS422/RS485 physical layer translation via external transceivers.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| USB Speed | Full-Speed at 12 Mbps - meets USB 2.0 compliance without external PHY or termination resistors. |
| UART Data Rate | Up to 3 Mbps - enables high-throughput bridging for real-time instrumentation and industrial controllers. |
| FIFO Depth | 256 bytes TX + 256 bytes 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 (e.g., DTR/DSR) depending on interface mode. |
| Operating Voltage | 1.71 V to 5.5 V - supports direct interfacing with 1.8 V, 3.3 V, and 5 V logic domains without level shifters. |
| Temperature Range | –40°C to +105°C (automotive grade) - qualified for under-hood and industrial edge environments. |
| ESD Rating | 2.2 kV HBM - provides robust handling during board assembly and field deployment in unshielded enclosures. |
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 | 1.71–5.5 V core power for USB and digital logic; decoupling required near pin. |
| VCCD | I/O supply | Configurable voltage domain for UART/GPIO I/O levels; independent of VDDD. |
| USBDP / USBDM | USB differential pair | Full-Speed USB interface with integrated 1.5 kΩ pull-up and 22 Ω series resistors. |
| RxD / TxD | UART receive/transmit | Default 2-pin UART; supports 4/6/8-pin expansion with RTS/CTS/DTR/DSR/DCD/RI. |
| nXRES | Active-low reset | Asynchronous reset input; internal pull-up ensures valid startup without external circuitry. |
| VBUS | USB bus voltage sense | Detects USB host connection; enables self-powered mode operation when VBUS = 0 V. |
Key Features
| Feature | Design Value |
|---|---|
| Configurable UART pin count | Supports 2-, 4-, 6-, or 8-pin interface mapping via flash configuration-enables reuse across RS232, RS422, and RS485 designs without PCB change. |
| Unique serial number | Per-device COM port locking on Windows hosts-eliminates port reassignment issues in multi-device embedded systems. |
| On-chip 512-byte flash | Stores VID/PID, descriptors, UART settings, and BCD mode-removes need for external EEPROM in production firmware. |
| BCD v1.2 peripheral detection | Identifies downstream charging ports (SDP/CDP/DCP) without host-side driver changes-enables smart battery management in portable medical devices. |

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 | Dual-channel UART with same GPIO count and RS485 support; larger 32-QFN package. | Required for simultaneous bridging of two legacy serial buses (e.g., Modbus RTU + ASCII). | Select when concurrent multi-protocol serial access is needed; not pin-compatible. |
| FTDI FT232RL | Single-channel, no BCD support, fixed 2-pin UART, 3.3 V only I/O, no flash configuration memory. | Limited to basic CDC COM port use; lacks automotive temp range and RS485 flexibility. | Choose for cost-sensitive, non-automotive designs where flashless operation and simple 2-wire UART suffice. |
Compared with CY7C65223-24LQXSTXUMA1, the CY7C65223D adds channel count at the expense of footprint and pinout compatibility, while the FT232RL trades configurability, temperature range, and BCD capability for lower unit cost and simpler layout.

FAQ
Does CY7C65223-24LQXSTXUMA1 require external crystal or oscillator?
No. The device integrates a factory-trimmed 48 MHz oscillator for USB timing and a 32 kHz oscillator for suspend/resume functions-no external crystal, capacitors, or clock source is needed for full USB 2.0 Full-Speed operation.
Can the UART interface be configured for RS485 half-duplex operation?
Yes. The CY7C65223 supports RS485 via external transceiver; its GPIOs or RTS# signal can drive the DE/RE control lines, and hardware flow control ensures automatic direction switching synchronized with transmit/receive state.
Is the unique serial number feature enabled by default?
Yes. Each unit ships with a factory-programmed, immutable 64-bit serial number stored in one-time programmable memory-this enables persistent COM port assignment on Windows without user intervention or additional configuration.
What operating systems support the VCOM driver without third-party tools?
Native VCOM drivers are provided for Windows (XP through 10, 32/64-bit), macOS (10.6+), and Linux (kernel 2.6.35+); no SDK or custom application library is required for basic CDC-class enumeration and serial communication.
