Chipi-X Cable
Chipi-X is a USB to full-handshake RS232 cable with a male DB9 connector. This cable is
available with or without an enclosure.
1
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).
1.1 Features
Entire USB protocol handled on the
FT232XS 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.
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).
Fully assisted hardware or X-On / X-Off
software handshaking.
Integrated MTP-ROM for storing USB VID,
PID, serial number and product description
strings.
Data transfer rates from 300 baud to 250
kilo-baud at RS232 voltage levels.
Low operating and USB suspend current.
512 byte receive buffer and 512 byte
transmit buffer utilising buffer smoothing
technology to allow for high data
throughput
Adjustable receive buffer timeout.
Low USB bandwidth consumption.
USB 2.0 Full Speed compatible.
-40°C to 85°C extended operating
temperature range.
Latch-up Free
Use of FTDI devices in life support and/or safety applications is entirely at the user’s risk, and the user agrees
to defend, indemnify and hold harmless FTDI from any and all damages, claims, suits or expense resulting
from such use.

Internal MTP ROM Configuration
Following a power-on reset or a USB reset the FT231X will scan its internal MTP ROM and read the USB
configuration descriptors stored there. The default values programmed into the internal MTP ROM in the
FT231XS used on the Chipi-X are shown in Table 8.1.
