FT230XQ-R集成電路（IC）的控制器規(guī)格書PDF中文資料

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-time programmable (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.

? Configurable I/O pin output drive strength; 4 mA (min) and 16 mA (max).

? Integrated power-on-reset circuit.

? Fully integrated AVCC supply filtering - no 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 85?C.

? Available in compact Pb-free 16 pin SSOP and 16 pin QFN packages (both RoHS compliant).
