General Description
Ordering Information
The MCS7705 controller provides bridging between
the Universal Serial Bus (USB) port, and a Parallel
Printer port. This device contains all the necessary
logic to communicate with the host computer via
the USB Bus. It supports Printers with hardware
accelerated SPP mode.
Commercial Grade (0° C to +70° C)
MCS7705CQ-GR
48-LQFP
RoHS
In addition, the MCS7705 contains a 3.3V regulator
and operates in Bus-Powered mode.
The MCS7705 has a reduced frequency (6MHz)
crystal oscillator.
This combination of features
allows significant cost savings in system design
along with straightforward implementation of
Parallel Printer port functionality into PC peripherals
using the host’s USB port.
