Description
STEVAL-PCC003V1
Data Brief
For demonstration purposes the USB
microcontroller used is the ST72F63BE2 8-bit
microcontroller. The STUSB03 connected with a
USB controller is ideal for use in mobile phones,
digital cameras, printers, PDAs, etc. All the
hardware components except the transceiver IC
are the same for the STEVAL-PCC003V1 and
STEVAL-PCC004V1 demonstration boards. The
demonstration board is comprised of one mini-B
USB connector, a USB controller, a USB
transceiver, two 2-to-4 demultiplexers and all
required discrete components (pull-up resistors,
series resistors and power supply capacitors).
The device can be configured through a set of
jumpers and the main signals can be accessed
through test points. The demonstration board is
powered from a USB mini-B or, optionally, from an
external supply. The STUSB03 transceiver is
connected at the USB communication lines of the
microcontroller.
