Product details
Overview
CY7C64225-28PVXC from Cypress Semiconductor is a USB 2.0 Full-Speed to UART bridge controller integrating USB SIE, UART, 24 MHz oscillator, 3.3 V regulator, and on-chip flash. It operates from single 3.3 V or 5 V supply, supports baud rates up to 230.4 kbps, and delivers bus-powered or self-powered operation in industrial metering and medical device interfaces.
For engineers reviewing the CY7C64225-28PVXC datasheet, CY7C64225-28PVXC pinout, CY7C64225-28PVXC application, or CY7C64225-28PVXC equivalent, key selection criteria include suspend current (225 µA @ 5 V), hardware flow control (RTS/CTS/DTR/DSR), VID/PID programmability, and SSOP-28 package compatibility with legacy UART peripherals.
Technical Context
The device implements a dedicated USB Serial Interface Engine (SIE) compliant with USB 2.0 Full-Speed (12 Mbps), certified under TID 40001425. Its UART core supports configurable data format (8N1, 8E1, 8O1), parity error detection, and framing overrun handling.
Suspend/resume logic drives SUSPEND low during USB bus suspend and enables remote wake-up via WAKE pin when host permits. Internal 24 MHz oscillator feeds both SIE and baud rate generator, eliminating external crystal requirements.

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 |
|---|---|---|---|
| FT232RL | Requires external 6 MHz crystal; no integrated regulator or flash; lower max baud rate (3 Mbps theoretical but limited to ~2 Mbaud practical) | Lacks VID/PID programmability and suspend current optimization; less suitable for bus-powered portable medical devices | Select when cost sensitivity outweighs design simplicity and when external crystal layout is acceptable |
| CY7C65213 | Newer generation; supports USB 2.0 High-Speed (480 Mbps); includes GPIOs and enhanced power management (10 µA suspend) | Higher integration for multi-function designs; requires updated driver stack and firmware configuration tools | Select for next-gen designs requiring higher bandwidth or additional I/O, accepting toolchain migration effort |
Compared with FT232RL and CY7C65213, CY7C64225-28PVXC offers optimal balance of integration (oscillator, regulator, flash), proven USB-IF certification, and industrial temperature support-making it ideal for cost-sensitive, space-constrained, and field-deployable UART bridging where design stability is prioritized over cutting-edge features.

FAQ
Does CY7C64225-28PVXC require an external crystal?
No. The device integrates a 24 MHz oscillator, eliminating the need for external crystal or resonator components. This reduces bill-of-materials count, PCB area, and layout complexity while ensuring consistent USB timing compliance across temperature and voltage ranges.
Can the VID and PID be customized for end-product branding?
Yes. Using the CyUsbUart configuration utility, users can program custom 16-bit Vendor ID (VID) and Product ID (PID) values into on-chip flash memory. Default values are 0x04B4/0x0008, but OEMs may assign unique identifiers to support branded driver installation and device enumeration.
What is the maximum reliable baud rate with hardware flow control enabled?
Hardware flow control (RTS/CTS) is supported up to 115200 bps. At 230400 bps, flow control is disabled per device specification. For high-speed applications requiring handshaking, 115200 bps remains fully functional with full error detection and buffer watermark management.
Is CY7C64225-28PVXC compatible with Linux and Android platforms?
Yes. Cypress provides open-source drivers and kernel module support for Linux (including mainline kernels) and Android. The device enumerates as a standard CDC ACM class device, enabling immediate use with generic serial terminal applications without proprietary driver installation.
