FT230X, FT231X, FT234XD – Full Speed USB to UART, FTDI Chip

The FTDI Chip FT230X and FT234XD are Ful Speed USB to basic serial UART interface devices. The FT231X is a Full Speed USB to Full Handshake UART interface.
They have a fully integrated MTP memory and an integrated clock circuit which requires no external crystal which helps to reduce external component count.
Capable of operating up to 3 MBaud, with low power consumption (8 mA), all USB to UART devices operate efficiently with USB host controllers. They use as little bandwidth as possible.
The FT230X includes the complete FT-X series feature set and enables USB to be added into a system design quickly and easily over a UART interface.

– Fully integrated MTP memory, clock generation, AVCC filtering, Power-On Reset (POR) and LDO regulators.
– Configurable CBUS I/O Pin Options.
– Asynchronous and Synchronous Bit Bang Modes.
– Operates at between +3.3 V and +5.25 V. A nominal operational mode current of 8 mA and a nominal USB suspend mode current of 125 μA.

FT232R – USB to Serial UART with Clock Generator, FTDI Chip

The FTDI Chip FT232R is a USB to serial UART interface with optional clock generator output. Asynchronous and synchronous bit bang interface modes are also available. Together with EEPROM, clock circuit and USB resistors effectively makes it a “3 in 1” chip for some applications. The internally generated clock (6 MHz, 12 MHz, 24 MHz, and 48 MHz) can be 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. It can then be used to protect customer application software from being copied. Royalty-free drivers for the most common operating systems are available from FTDI website. http://www.ftdichip.com

The FT232R is available in compact 28-pin SSOP (RS 406-580) and 32-pin QFN (RS 730-0168) packages.

Features & Benefits

• 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.

Serial I/O Peripherals, FTDI Chip

A Universal Asynchronous Receiver/Transmitter, abbreviated (UART) and universal synchronous/asynchronous receiver/transmitter (USART) are commonly used in conjunction with communication standards such as EIA, RS-232, RS-422 or RS-485. It takes bytes of data and transmits or receives the individual bits in a sequential fashion. Modem (Modulator-Demodulator) that modulates an analogue carrier signal to encode digital information and demodulates the signal to decode the transmitted information includes the UART function for transmission over telephone lines.

Universal Asynchronous Receiver/Transmitter (UART), EXAR

Exar offer a variety of UARTs (Universal Asynchronous Receiver Transmitter) with a broad range of first in, first out (FIFO) depths, while supporting popular central processing unit (CPU) bus interface such as 8-bit VLIO.
