www.DataSheet4U.com Freescale Semiconductor Advance Information Document Number: MC33742 Rev. 10.0, 5/2007 System Basis Chip (SBC) with Enhanced High-Speed CAN Transceiver The 33742 and the 33742S are SPI-controlled System Basis Chips (SBCs) combining many frequently used functions along with a CAN 2.0compliant transceiver, used in many automotive electronic control units (ECUs). The 33742 SBC has a fully protected fixed 5.0 V low dropout internal regulator with current limiting, overtemperature pre-warning, and reset. A second 5.0 V regulator can be implemented using external pass PNP bipolar junction pass transistor driven by the SBC’s external V2 sense input and V2 output drive pins. The SBC has four main operating modes: Normal, Standby, Stop, and Sleep mode.
