www.DataSheet4U.com Freescale Semiconductor Technical Data Document order number: MC33780 Rev 3.0, 5/2006 Dual DBUS Master with Differential Drive and Frequency Spreading The 33780 is a master device for two differential DBUS buses. It contains the logic to interface the buses to a standard serial peripheral interface (SPI) port and the analog circuitry to drive data and power over the bus as well as receive data from the remote slave devices. The differential mode of the 33780 generates low.
