Future Technology Devices International Ltd. FT232RL USB UART IC
The FT232RL 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 enabling 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 utilising 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.
Unique USB FTDIChip-ID™ feature.
Configurable CBUS I/O pins.
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
FT232RL - USB UART IC
The FT232RL is that the latest device to be adscititious to FTDI’s vary of USB UART interface microcircuit Devices. The FT232RL could be a USB to serial UART interface with nonmandatory clock generator output, and also the new FTDIChip-ID™ security electronic device feature.
additionally, asynchronous and synchronous bit bang interface modes square measure on the market. USB to serial styles mistreatment the FT232RL are additional simplified by absolutely integration the external EEPROM, clock circuit and USB resistors onto the device.
The FT232RL adds 2 new functions compared with its predecessors, effectively creating it a "3-in-1" chip for a few application areas. The internally generated clock (6MHz, 12MHz, 24MHz, and 48MHz) may be brought out of the device and accustomed drive a microcontroller or external logic.
a novel range (the FTDIChip-ID™) is burnt into the device throughout manufacture and is legible over USB, therefore forming the idea of a security electronic device which might be accustomed defend client application package from being derived.
The FT232RL is obtainable in Pb-free (RoHS compliant) compact 28-Lead SSOP and QFN-32 packages.
PICAxe Overview and Programming with FT232RL
This video discusses the PICaxe, and how to program it with the standard FT232RL FTDI USB to Serial converer. Note: this is the onboard chip on the Arduino boards. You could actually use the RX TX pins on the Duemilanove to program the PICaxe.
