Product details
Overview
CY7C64225-28PVXCT from Cypress Semiconductor is a USB 2.0 Full-Speed to UART bridge controller integrating USB SIE, UART engine, 24 MHz oscillator, 3.3 V regulator, and flash for configuration storage. It operates from single 3.3 V or 5 V supply, supports baud rates up to 230.4 kbps, hardware flow control (RTS/CTS/DTR/DSR), and LED indicators for Tx/Rx activity - deployed in USB-to-RS-232 cables and industrial metering interfaces.
For engineers reviewing the CY7C64225-28PVXCT datasheet, CY7C64225-28PVXCT pinout, CY7C64225-28PVXCT application, or CY7C64225-28PVXCT equivalent, key selection criteria include suspend current (207 µA @ 3.3 V), USB-IF certification (TID 40001425), bus/self-powered mode flexibility, configurable VID/PID via flash, and native Windows/Linux/Mac driver support.
Technical Context
The device implements a dedicated USB Serial Interface Engine (SIE) compliant with USB 2.0 Full-Speed (12 Mbps), with integrated transceiver and 1.5 kΩ D+ pull-up resistor. It uses an internal 24 MHz oscillator as clock source for both USB and UART subsystems, eliminating external crystal requirements.
UART functionality includes programmable baud rate generation (300–230400 bps), full framing support (8N1, 8E1, 8O1), and hardware flow control using four dedicated I/Os (RTS, CTS, DTR, DSR). Flow control is disabled by default and unsupported at 230400 bps.

Equivalent & Alternatives
The following parts are listed as comparable options for similar USB-to-UART bridge applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Ftdi FT232RL | Requires external 6 MHz crystal; no integrated regulator; 5 V only; no flash-based configuration | Lacks suspend current optimization (typ. 2 mA); no native Linux/macOS driver certification | Preferred where crystal-based timing stability is prioritized over BOM simplicity |
| Cypress CY7C65213 | USB 2.0 Full-Speed; integrated 48 MHz oscillator; lower suspend current (100 µA); supports GPIO expansion | Targeted for low-power industrial designs; adds 4 configurable GPIOs beyond UART signals | Recommended when additional I/O control or sub-100 µA suspend operation is required |
Compared with FT232RL and CY7C65213, CY7C64225-28PVXCT offers balanced integration (oscillator + regulator + flash) and broad OS driver support, making it optimal for cost-sensitive, medium-power USB-UART adapter designs requiring field-programmable identity and LED feedback.

FAQ
Does CY7C64225-28PVXCT require an external crystal?
No. The device integrates a factory-trimmed 24 MHz oscillator, eliminating the need for an external crystal or clock source. This reduces bill-of-materials count, PCB footprint, and layout complexity while maintaining sufficient timing accuracy for USB Full-Speed and UART operation across the commercial temperature range.
Can the VID/PID and string descriptors be customized in production?
Yes. The on-chip flash memory supports field programming of VID/PID (e.g., 0x04B4/0x0008 default), manufacturer string (≤26 chars), product string (≤24 chars), and power mode via Cypress's CyUsbUart configuration utility. This enables OEM branding and avoids conflicts in multi-device USB environments.
What is the maximum UART baud rate supported, and is flow control available at that rate?
The device supports up to 230400 bps, but hardware flow control (RTS/CTS/DTR/DSR) is explicitly disabled at this rate per datasheet specification. Flow control remains functional at all lower standard rates (e.g., 115200, 57600, 9600 bps) and is configured via host software, not hardware strapping.
How does the device handle USB suspend and resume in bus-powered mode?
In bus-powered mode, the device asserts SUSPEND (active-low) and draws only 207 µA at 3.3 V when the USB bus enters suspend state. Resume occurs automatically on USB bus activity or via active-high assertion of the WAKE pin - provided remote wake-up is enabled in flash configuration and permitted by host during enumeration.
