Usb To Uart (Ft232R) - Analog Devices ADSP-SC573 EZ-KIT Manual

USB to UART (FT232R)

interface directly with 3.3 V to 5 V microcontrollers. An SPI interface is provided for transceiver control and for
retrieving status information. Bus connections are truly floating when power is off.
These features make the TJA1145 the ideal choice for high-speed CAN networks containing nodes that are always
connected to the battery supply line but, in order to minimize current consumption, are only active when required
by the application.
USB to UART (FT232R)
The FT232R is a USB-to-serial-UART interface with the following advanced features:
• Single chip USB to asynchronous serial data transfer interface
• Entire USB protocol handled on the chip. No USB specific firmware programming required
• Fully-integrated 1024 bit EEPROM storing device descriptors and CBUS I/O configuration
• Fully-integrated USB termination resistors
• Fully-integrated clock generation with no external crystal required, plus optional clock output selection ena-
bling a glue-less interface to external MCU or FPGA
• Data transfer rates from 300 baud to 3 Mbaud (RS422, RS485, RS232) at TTL levels
• 128 byte receive buffer and 256 byte transmit buffer utilizing buffer smoothing technology to allow for high-
data throughput
• FTDI's royalty-free Virtual Com Port (VCP) and Direct (D2XX) drivers eliminate the requirement for USB
driver development in most cases.
• Transmit and receive LED drive signals
• UART interface support for 7 or 8 data bits, 1 or 2 stop bits and odd / even / mark / space / no parity
• FIFO receives and transmits buffers for high-data throughput
• Device supplied pre-programmed with unique USB serial number
• Supports bus powered, self-powered and high-power bus powered USB configurations
• Integrated +3.3V level converter for USB I/O
• Integrated level converter on UART and CBUS for interfacing to between +1.8V and +5V logic
• True 5V/3.3V/2.8V/1.8V CMOS drive output and TTL input
• Configurable I/O pin output drive strength
• Integrated power-on-reset circuit
• Fully-integrated AVCC supply filtering - no external filtering required.
• UART signal inversion option
