FT232RL USB to Serial Adapter for PIC AVR ATMEGA ARDUINO MCUs


Posted on Feb 6, 2014

FT232RL USB to Serial UART (TTL) Adapter is a simple and inexpensive way to connect PIC, AVR or ATMEGA MCUs to a PC or Mac via USB connection. FT232RL is an impressive chip because it implements full v2. 0 USB protocol, needs no external crystal, has integrated EEPROM for device ID and product description strings and comes with Royalty-Free driver

support for Windows, Linux, and Mac OSX. FT232RL chip provides two data lines RXD and TXD that are connected through 1K resistors to a microcontroller such as PIC AVR ATMEGA ARDUINO. Up to 500mA of +5V power can be obtained from USB port and used to power both FT232RL chip and your favourite MCU. When connected to a PC FT232RL is mounted and shows as Virtual COM port in Device Manager making it easy to send and receive data from PIC, AVR or ATMEGA microcontrollers. The FT232R adds two new functions compared with its predecessors, effectively making it a "3-in-1" chip for some application areas. The internally generated clock (6MHz, 12MHz, 24MHz, and 48MHz) can be brought out of the device and used to drive a microcontroller or external logic. A unique number (the FTDIChip-ID) is burnt into the device during manufacture and is readable over USB, thus forming the basis of a security dongle which can be used to protect customer application software from being copied. Integrated Clock Circuit - Previous generations of FTDI`s USB UART devices required an external crystal or ceramic resonator. The clock circuit has now been integrated onto the device meaning that no crystal or ceramic resonator is required. However, if preferred, an external 12MHz crystal can be used as the clock source. Integrated EEPROM - Previous generations of FTDI`s USB UART devices required an external EEPROM if the device were to use USB Vendor ID (VID),...
