Introduction
The Chipi-X cable is a USB to RS232 level full-handshake UART cable. Chipi-X utilises FTDI’s FT231XS USB to full-handshake UART IC and FT3243S RS232 transceiver IC. A male DB9 (aka DE9) connector provides the connectivity for RS232 communications and a USB-A plug tethered by a 10cm cable to the PCB provides connectivity for USB communications.
All components used are Pb-free (RoHS compliant).

FEATUREs
• Entire USB protocol handled on the
   FT231XS chip
• FTDI’s royalty-free VCP and D2XX drivers
   eliminate the requirement for USB driver
   development in most cases
• UART interface support for 7 or 8 data
   bits, 1 or 2 stop bits and odd / even /
   mark / space / no parity.
• Fully assisted hardware or X-On / X-Off
   software handshaking.
• Data transfer rates from 300 baud to 250
   kilo-baud at RS232 voltage levels.
• 512 byte receive buffer and 512 byte
   transmit buffer utilising buffer smoothing
   technology to allow for high data
   throughput
• Adjustable receive buffer timeout.
• ESD protection on RS232 I/Os exceeding
   ±15kV IEC1000-4-2 Air Gap Discharge,
   ±15kV for Human Body Mode (HBM) and
   ±8kV IEC1000-4-2 Contact Discharge.
• ESD protection on USB lines exceeding ±2kV
   for Human Body Mode (HBM), ±200V for
   Machine Mode (MM) and ±500V for Charged
   Device Mode (CDM).
• Integrated MTP-ROM for storing USB VID,
   PID, serial number and product description
   strings.
• Low operating and USB suspend current.
• Low USB bandwidth consumption.
• USB 2.0 Full Speed compatible.
• -40°C to 85°C extended operating
   temperature range.
• Latch-up Free
