Freescale Semiconductor Document Number: USB2SERDS Rev. 2, 10/2012 Data Sheet: Advance Information USB2SERA10 24-pin QFN USB2SERA10 Data Sheet Case 1897 USB to UART Application Specific IC Introduction Configurable password to protect the device from additional parameter modifications Freescale Ready Play Solutions integrate a certified function Data formats supported 8 bits data, 1 and 2 stop bits to different applications allowing customers to add features Parity odd, even, no parity while reducing development cost. This simplifies design cycles and enables scalability in applications and systems. Hardware flow control (RTC / CTS) or Software Xon/Xoff flow control The USB2SER is a USB to UART bridge controller on a RS485 TXEN signal to support RS485 5x5mm lead free QFN24. It is a simple low cost solution to enable a USB for an embedded system with a UART port, USB and UART activity pins to indicate reducing external component counts. It supports USB 2.0 full- communication activity and fail sequences speed and TTL RS232 or RS485 UART with options for Drivers support hardware flow control, Software Flow control (Xon-Xoff), The USB2SER can act as a CDC standard device that even or odd parity, and stop bits configuration. eliminates the need for custom drivers for operation when the Features flow-control is not needed (only an INF file is required). Single chip USB to UART Data Transfer (RS232 or For flow control support, COM emulator drivers are available RS485) for: USB specification 2.0 compliant, full speed Windows XP 32-bits and 64-bits versions (12 Mbps) Windows Vista 32-bits and 64-bits versions User programmable custom baud rates from 300 bps Windows 7 32-bits and 64-bits versions to 115200 bps Linux Kernel 2.6.34 and higher 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 RESUME signal to request a remote wake-up and provided to customize the Product ID, Vendor ID, Product SUSPEND output to indicate that the device is in strings, current consumption parameters and password suspended mode protection option, to prevent further modifications to the device information.
