The 33989 is a monolithic integrated circuit combining many functions used by microcontrollers (MCU) found in utomotive Engine Control Units (ECUs). The device incorporates functions such as: two voltage regulators, four high oltage (wake up) inputs, a 1Mbaud capable CAN physical interface, an SPI interface to the MCU and VSUP monitoring nd fault detection circuitry. The 33989 also provides reset control in conjunction with VSUP monitoring and the atchdog timer features. Also, an Interrupt can be generated, for the MCU, based on CAN bus activity as well as ode changes.
