Infineon Technologies CY7C65213-28PVXI

Overview

CY7C65213-28PVXI from Cypress Semiconductor is a USB 2.0 Full-Speed (12 Mbps) USB-to-UART bridge controller with integrated 48-MHz oscillator, 256-byte TX/RX buffers, and support for RS232/RS422 interfaces. It operates from 1.71–5.50 V, delivers up to 3 Mbps UART data rate, and includes 8 GPIOs and 512-byte flash for VID/PID/serial number storage. Used in blood glucose meters and USB-to-UART cables for legacy peripheral upgrades.

For engineers reviewing the CY7C65213-28PVXI datasheet, CY7C65213-28PVXI pinout, CY7C65213-28PVXI application, or CY7C65213-28PVXI equivalent, key selection criteria include UART interface configuration (2/4/6/8-pin), BCD-compliant peripheral detection, CDC/PHDC class support, and industrial temperature range (–40 °C to 85 °C) compliance.

Technical Context

The device integrates a USB 2.0 Full-Speed Serial Interface Engine (SIE), asynchronous UART with hardware flow control (RTS#/CTS#, DTR#/DSR#), and battery charger detection (BCD Rev. 1.2) for SDP/CDP/DCP port identification. Its internal 48-MHz oscillator eliminates external crystal requirements, while the 32-kHz oscillator supports suspend/resume timing.

UART functionality supports 7–8 data bits, 1–2 stop bits, and parity modes (no/even/odd/mark/space), with error detection for framing, overrun, and parity. The 256-byte FIFO in each direction enables reliable full-duplex communication at baud rates from 300 to 3,000,000 bps, configurable via Windows utility or firmware API.

FAQ

Does CY7C65213-28PVXI require an external crystal?

No. It integrates a factory-trimmed 48-MHz oscillator, eliminating the need for external crystals or load capacitors. This reduces PCB footprint, BOM cost, and layout complexity while maintaining USB Full-Speed timing compliance. The internal oscillator is qualified across the full industrial temperature range (–40 °C to +85 °C) and supply voltage (1.71–5.50 V).

Can CY7C65213-28PVXI support RS485 communication?

No. CY7C65213 supports only RS232 and RS422 interfaces. RS485 support is exclusive to the CY7C65213A variant (e.g., CY7C65213A-28PVXI). The CY7C65213-28PVXI UART pins lack the tri-state control and polarity inversion required for half-duplex RS485 bus arbitration.

How is the unique serial number programmed and retained?

The unique serial number is written once to the 512-byte internal flash memory using Cypress's Windows-based configuration utility (CyConsole or USB-Serial Configuration Utility). It persists across power cycles and USB reconnections, ensuring consistent COM port assignment in Windows without requiring driver reinstall or registry edits.

What operating systems are supported for driver installation?

Cypress provides native drivers for Windows (XP through 10, 32-/64-bit), macOS (10.6+), Linux (kernel 2.6.35+), Windows CE, and Android (Gingerbread+). On Linux, both kernel CDC ACM driver support and user-mode libcyusbserial.so library are provided, enabling plug-and-play and custom application integration without root privileges.
