[INTERFACE] FTDI FT234XD USB2SERIAL

Posted in Good Device!! by firepooh

FTDI 에서 새로 나온 FT234XD USB2SERIAL 입니다.

이것 저것 다 빼 버리고, 흐름제어와 컨트롤 I/O 한개만 나와 있네요.

그래서 토탈 Size가 3x3mm 입니다.

이런 형태도 좋긴 한데... MicroUSB 단자 몇번 쓰면 100% 위로 덜렁 거릴 것 같은데...
좀 튼튼한걸로 쓰지 짜슥들.
MicroUSB DIP으로 단단한거 사용하고, 샤방샤방 LED1개 TX/RX Indicator용으로 달아주고 그냥 PCB타입이 아닌 PIN HEADER타입으로 만들면 좋겠다.



이런 타입도 좋긴 한데......





회로는 이렇게 되겠지...심플 심플 좋아라...


 Key Hardware 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 EEPROM for 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.
  • 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.
  • Battery Charger Detection. May be used by mobile devices to detect the presence of a charger on the USB port to enable higher current / faster charging of batteries.
  • 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.
  • True 3.3V CMOS drive output and TTL input.
    • (operates down to 1V8 with external pull ups and is also 5V tolerant)
  • Configurable I/O pin output drive strength.
  • Integrated power-on-reset circuit.
  • UART signal inversion option.
  • Internal 3.3V/1.8V LDO regulators
  • Low operating current of 8mA (typical) and USB suspend current of 125uA (typical) current.
  • Low USB bandwidth consumption.
  • UHCI/OHCI/EHCI host controller compatible.
  • USB 2.0 Full Speed compatible.
  • Extended operating temperature range: -40°C to 85°C
  • Available in compact Pb-free 12 Pin DFN package (RoHS compliant).
