General Description 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 municate with the host puter via the USB Bus. It supports Printers with hardware accelerated SPP mode.
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 bination 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.
