Future Technology
Introduction
The UMFT231XE is a development module
for FTDI‟s FT231XQ, one of the devices
from FTDI‟s range of USB interface bridging
integrated circuit devices. FT231X is a USB
to UART interface with a battery charger
detection feature, which can allow batteries
to be charged with a higher current from a
dedicated charger port (without the
FT231X being enumerated). In addition,
asynchronous and synchronous bit bang
interface modes are available. The
internally generated clock (6MHz, 12MHz
and 24MHz) can be brought out of the on
one of the CBUS pin to be used to drive a
microprocessor or external logic.
The UMFT231XE is a module which is
designed to plug into a standard 0.6” wide
20 pin DIP socket. All components used,
including the FT231XQ are Pb-free (RoHS
compliant).
