FT232R Introduction
With the development of computer technology, parallel and serial ports on your PC slowly disappeared, and now even the parallel port of the desktop are rare. But for engineers, parallel and serial interfaces are essential, especially serial port. For no serial computer, the most convenient solution is to use USB to serial chip to a virtual serial port out, many manufacturers have to produce such chips, such as silicon LABS of CP210x series, TI's TUSB3410, Nanjing Qin Heng CH34x series, FTDI's FT232 series, Prolific's PL230x series, Echo of ARK3116 like. From the stability point of view, it is still the most reliable FT232 series, you can use the debugger it to feel at ease without worrying about blue screen appears.
FT232R chip is a single-chip solution, the general use of the basic need of peripherals, and even crystal, USB termination resistors placed EEPROM product information have been integrated within the. FT232R There are some more useful features, details can be found in FT232R data sheet.
Hardware description
