MCS7720

MCS7720 USB 1.1 to Dual Serial Controller Features USB Specification 1.1 Compliant Single 5V Operation On-Chip Regulator Low Power Dual Serial Ports Supports up to 920Kbps Data Rate Supports 8,7,6 & 5 Data Widths Supports Even, Odd, Mark, Space & None Parities Supports 1, 1.5 & 2 Stop Bits Internal Power-On Reset Available in 48-pin QFP Package Applications High-Speed Modems Monitoring Equipment Serial Networking Application Note AN-7720 Evaluation Board MCS7720-EVB General Description The MCS7720 controller provides bridging between the Universal Serial Bus (USB) input and two enhanced UART ports. This device contains all the necessary logic to communicate with the host computer via the USB Bus. In addition, the MCS7720 contains a 3.3V regulator, operates in Bus-Powered mode, and has a reduced frequency (6 MHz) 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.
