Product details
Overview
CY7C65213-28PVXIT from Cypress Semiconductor is a USB 2.0 Full-Speed (12 Mbps) USB-to-UART bridge controller in 28-pin SSOP package, supporting single-channel UART up to 3 Mbps, 256-byte TX/RX buffers, and USB CDC/PHDC/vendor-class compliance. It enables legacy UART peripherals to gain USB connectivity in battery-operated medical devices, POS terminals, and industrial test equipment.
For engineers reviewing the CY7C65213-28PVXIT datasheet, CY7C65213-28PVXIT pinout, CY7C65213-28PVXIT application, or CY7C65213-28PVXIT equivalent, key selection criteria include RS232/RS422 interface support (not RS485), BCD-compliant peripheral detection, integrated 48-MHz oscillator, 1.71–5.50 V operation, and 8 GPIOs with LED drive capability.
Technical Context
The device integrates a USB 2.0 Full-Speed Serial Interface Engine (SIE), UART transceiver, internal 48-MHz oscillator, 512-byte flash for descriptor storage, and voltage regulator - eliminating external crystal and LDO requirements. It implements CDC class enumeration and supports configurable VID/PID, serial number persistence, and bus-/self-powered modes.
UART functionality includes hardware flow control (RTS#/CTS#, DTR#/DSR#), break signal generation, parity/framing/error detection, and programmable data format (7/8 data bits, 1/2 stop bits, five parity options). GPIOs are software-configurable for power control, LED indication, sleep signaling, or BCD output.

FAQ
Does CY7C65213-28PVXIT support RS485 communication?
No. CY7C65213-28PVXIT supports UART-to-RS232 and UART-to-RS422 interfaces only. RS485 support requires CY7C65213A variant (e.g., CY7C65213A-28PVXI), which adds RS485 transceiver compatibility in its UART interface block.
Can the COM port number be fixed across USB replug events?
Yes. The device supports unique serial number programming via Cypress's configuration utility. When enabled, this feature binds the assigned COM port number to the specific hardware instance, preventing port reassignment during hot-plug cycles in Windows and Linux environments.
What is the maximum UART baud rate supported?
The CY7C65213-28PVXIT supports UART data rates up to 3 Mbps. This is achieved using the internal 48-MHz clock and programmable divisor; actual achievable rate depends on configured data format and flow control settings, but 3 Mbps is verified per datasheet Table 9.
Is external crystal required for USB or UART operation?
No. The device integrates a factory-trimmed 48-MHz oscillator for USB timing and UART baud generation. No external crystal, resonator, or load capacitors are needed - reducing bill-of-materials and layout complexity while maintaining ±1% baud accuracy across voltage and temperature.
