The device incorporates functions such as: two voltage regulators, four high voltage (wake up) inputs, a 1Mbaud capable CAN physical interface, an SPI interface to the MCU and VSUP monitoring and fault detection circuitry. The 33989 also provides reset control in conjunction with VSUP monitoring and the watchdog timer features. Also, an Interrupt can be generated, for the MCU, based on CAN bus activity as well as mode changes. Features • VDD1: Low Drop Voltage Regulator, Current Limitation, Overtemperature Detection, Monitoring, and Reset Function • VDD1: Total Current Capability 200 mA • V2: Tracking Function of VDD1 Regulator. Control Circuitry for External Bipolar Ballast Transistor for High Flexibility in Choice of Peripheral Voltage and Current Supply • Low Stand-By Current Consumption in Stop and Sleep Modes • High-Speed 1 MBaud CAN Physical Interface • Four External High Voltage Wake-up Inputs Associated with HS1 VBAT Switch • 150 mA Output Current Capability for HS1 VBAT Switch Allowing Drive of External Switches Pull-Up Resistors or Relays • VSUP Failure Detection • 40 V Maximum Transient Voltage • Pb Free designated by suffix code EG SYSTEM BASIS CHIP WITH HIGH-SPEED CAN DW SUFFIX EG SUFFIX (PB-FREE) 98ASB42345B 28-PIN SOICW ORDERING INFORMATION Device MC33989DW/R2 MCZ33989EG/R2 Temperature Range (TA) -40°C to 125°C Package 28 SOICW 33989 VPWR 5.0 V VDD1 VSUP V2 MCU GND RST INT V2CTRL V2 HS1 Local Module Supply CS CS SCLK SPI SCLK MOSI MOSI MISO MISO L0 L1 L2 Wake-Up Inputs L3 WD Safe Circuits TX CANH RX CANL Twisted CAN Bus Pair Figure 1.
