MCS7717
The MCS7717 controller provides bridging between the Universal Serial Bus (USB) input and enhanced UART, 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.
In addition to its host interface, the MCS7717 is a stand-alone USB hub device which complies with USB Specification Rev. 1.1. It integrates a serial interface engine, hub repeater, hub controller, transceivers and a 3.3 V regulator. The MCS7717 operates in bus-powered mode.
The MCS7717 has a serial interface for external EEPROM access and a reduced frequency (6 MHz) crystal oscillator. This combination of features allows significant cost savings in system design along with straightforward implementation of serial, parallel and USB functionality into PC peripherals.
