UB232R开发板套件编程器的评估演示板及套件规格书PDF中文资料

Introduction

The UB232R is the smallest USB – serial development module in the FTDI product range. To minimise the size of the module, the UB232R uses a standard USB mini-B connector. It is ideal for new development purposes as well as a platform for adding a USB interface to existing product designs.

The UB232R is based on the FTDI FT232RQ USB to Serial UART IC which handles all the USB signalling and protocols. The FT232R datasheet, DS_FT232R, is available at http://www.ftdichip.com, The UB232R supports RTS/CTS hardware handshaking and is USB powered. The module supports data transfer rates from 300 baud to 3 Mbaud (RS422, RS485, RS232 and at TTL levels). In addition, two of the configurable CBUS pins of the FT232R are made available on the UB232R connector, allowing the UB232R to provide clock signals to external logic or they can be used to drive signal traffic indicator LEDs.
