USB2SER Data Sheet

USB to UART Application Specific

•

Hardware flow control (RTC / CTS) or Software

Xon/Xoff flow control

Introduction

The USB2SER is a USB to UART bridge controller on a

5 x 5 mm lead free QFN24. It is a simple low cost solution to

enable a USB for an embedded system with a UART port,

reducing external component counts. It supports USB 2.0 full-

speed and TTL RS232 or RS485 UART with options for

hardware flow control, Software Flow control (Xon-Xoff),

even or odd parity, and stop bits configuration.

•

RS485_TXEN signal to support RS485

USB and UART activity pins to indicate

communication activity and fail sequences

Drivers support

The USB2SER can act as a CDC standard device that

eliminates the need for custom drivers for operation when the

flow-control is not needed (only an INF file is required).

Features

•

Single chip USB to UART Data Transfer (RS232 or

RS485)

For flow control support, COM emulator drivers are available

for:

USB specification 2.0 compliant, full speed

(12 Mbps)

•

Windows XP 32-bits and 64-bits versions

Windows Vista 32-bits and 64-bits versions

Windows 7 32-bits and 64-bits versions

Linux Kernel 2.6.34 and higher

User programmable custom baud rates from 300 bps

to 115200 bps

UART supports 8 bit data, 1 or 2 stop bits and odd,

even or no parity

Additionally to the drivers, a software configuration tool is

provided to customize the Product ID, Vendor ID, Product

strings, current consumption parameters and password

protection option, to prevent further modifications to the

device information. For driver installation and software go to:

RESUME signal to request a remote wake-up and

SUSPEND output to indicate that the device is in

suspended mode

•

Integrated 3.3 V regulator for a USB IO

Integrated Power-On-Reset circuit

The GUI and Driver Installer at www.freescale.com/usb2ser.

Integrated 2 MHz – 48 Mhz clock multiplier PLL

Package

Supports 2 MHz, 4 MHz, 6 MHz, 8 MHz, 12 MHz,

and 16 MHz external crystals with automatic crystal

frequency detection

USB2SER comes in a compact 5 x 5 mm Pb free RoHS

compliant QFN24.

•

USB bulk data transfer modes for data

communication

•

3 V to 5 V single supply operation

UHCI / OHCI / EHCI host controller compatible

Configurable USB VID, PID, and device

description strings in the internal flash

•

Configurable password to protect the device from

additional parameter modifications

•

Data formats supported 8 bits data, 1 and 2 stop bits

Parity odd, even, no parity
