USB to UART Application Specific IC

Introduction

Freescale Ready Play Solutions integrate a certified function

to different applications allowing customers to add features

while reducing development cost. This simplifies design

cycles and enables scalability in applications and systems.

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.

Features

•

Single chip USB to UART Data Transfer (RS232 or

RS485)

USB specification 2.0 compliant, full speed

(12 Mbps)

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

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

Integrated 2 MHz – 48 Mhz clock multiplier PLL

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

and 16 MHz external crystals with automatic crystal

frequency detection

USB bulk data transfer modes for data

communication

3 V to 5 V single supply operation

UHCI / OHCI / EHCI host controller compatible

•

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

Hardware flow control (RTC / CTS) or Software

Xon/Xoff flow control

Adjustable receive buffer timeout from 1 ms through

99 ms.

RS485_TXEN signal to support RS485

USB and UART activity pins to indicate

communication activity and fail sequences

24-pin QFN

Case 1897

Drivers support

The USB2SER can act as a CDC standard device that

eliminates the need for custom drivers for operation when

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

For flow control support, COM emulator drivers are available

for:

•

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

•

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:

The GUI and Driver Installer at

www.freescale.com/usb2ser.

Package

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

compliant QFN24.

•

Configurable USB, VID, PID, and device
