Infineon Technologies CY7C65213A-28PVXI

Overview

CY7C65213A-28PVXI from Cypress Semiconductor is a USB 2.0 Full-Speed (12 Mbps) USB-to-UART bridge controller supporting RS232/RS422/RS485 physical layer interfacing, 3 Mbps UART data rate, 256-byte TX/RX buffers, and integrated 48-MHz oscillator - deployed in industrial test equipment, POS terminals, and battery-operated medical devices such as blood glucose meters.

For engineers reviewing the CY7C65213A-28PVXI datasheet, CY7C65213A-28PVXI pinout, CY7C65213A-28PVXI application, or CY7C65213A-28PVXI equivalent, key selection criteria include RS485 support (vs. CY7C65213), BCD 1.2 peripheral detection, GPIO-configurable LED signaling, VCCIO voltage flexibility (1.71–5.50 V), and flash-programmable VID/PID/serial number persistence.

Technical Context

The device integrates a USB 2.0 Serial Interface Engine (SIE), asynchronous UART with hardware flow control (RTS#/CTS#, DTR#/DSR#), and configurable 8-pin GPIO block. It implements CDC, PHDC, and vendor-class USB device enumeration without external crystal or termination resistors.

Its dual-oscillator system (48 MHz for USB/UART, 32 kHz for suspend timing) enables bus-powered operation with <100 µA suspend current and supports both self-powered and bus-powered configurations across 1.71–5.50 V supply range, with industrial temperature rating (–40 °C to +85 °C).

FAQ

Does CY7C65213A-28PVXI require an external crystal?

No. The device integrates a precision 48-MHz oscillator for USB and UART timing, eliminating the need for external crystals or oscillators. This reduces PCB area, BOM count, and startup time - confirmed in the Functional Overview section of datasheet 001-81011 Rev. *O.

Can the COM port number be fixed across USB replugs?

Yes. The device supports a unique serial number feature stored in its 512-byte flash memory. When programmed via Cypress's configuration utility, this number binds the Windows COM port assignment permanently - preventing port number shifts during hot-plug cycles.

What is the maximum UART baud rate supported?

The CY7C65213A-28PVXI supports UART data rates up to 3 Mbps, verified in electrical specifications and functional testing. Baud rates from 300 to 3,000,000 bps are programmable via the configuration utility - including non-standard values not aligned to common divisor tables.

How does RS485 mode differ between CY7C65213 and CY7C65213A?

Only CY7C65213A supports RS485 interface capability. The CY7C65213 variant is limited to RS232/RS422. This distinction is explicitly documented in Table 1 (Features Comparison) of datasheet 001-81011 Rev. *O - RS485 support is the primary functional differentiator between the two part families.
