General Description
The MCS7715 controller provides bridging between the
Universal Serial Bus (USB) input an enhanced UART
port and an IEEE-1284 bi-directional printer port. This
device contains all the necessary logic to communicate
with the host computer via the USB bus.
In addition, the MCS7715 contains a 3.3V regulator and
operates in bus-powered mode.
The MCS7715 has a reduced frequency (6MHz) crystal
oscillator. This combination of features allows signifi-
cant cost savings in system design along with straight-
forward implementation of serial port functionality into
PC peripherals using the host’s USB port.
