FT230X USB TO BASIC UART IC
Document No.: FT_000566 Clearance No.: FTDI# 260 Version 1.3 Future Technology Devices International Ltd. FT230X (USB to BASIC UART IC)
The FT230X is a USB to serial UART interface with optimised pin count for smaller PCB designs and 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 2048 byte multi-timeprogrammable (MTP) memory, storing device descriptors and CBUS I/O configuration. 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, and RS232) at TTL levels. 512 byte receive buffer and 512 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. 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 Synchronous and asynchronous bit bang interface options with RD# and WR# strobes. USB Battery Charger Detection. Allows for USB peripheral devices to detect the presence of a higher power source to enable improved charging. Device supplied pre-programmed with unique USB serial number. USB Power Configurations; supports bus-powered, self-powered and bus-powered with power switching Integrated +3.3V level converter for USB I/O. True 3.3V CMOS drive output and TTL input; operates down to 1V8 with external pull ups. Tolerant of 5V input Configurable I/O pin output drive strength; 4 mA (min) and 16 mA (max). Integrated power-on-reset circuit. Fully integrated AVCC supply filtering external filtering required. UART signal inversion option. + 5V Single Supply Operation. Internal 3V3/1V8 LDO regulators Low operating and USB suspend current; 8mA (active-typ) and 70uA (suspend-typ). UHCI/OHCI/EHCI host controller compatible. USB 2.0 Full Speed compatible. Extended operating temperature range; -40 to 85C. Available in compact Pb-free 16 pin SSOP and 16 pin QFN packages (both RoHS compliant). -no Neither the whole nor any part of the information contained in, or the product described in this manual, may be adapted or reproduced in any material or electronic form without the prior written consent of the copyright holder.
