General Description
Ordering Information
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 significant cost savings in system design along with straightforward implementation of serial port functionality into
PC peripherals using the host’s USB port.
