MC33989PEGR2

MC33989PEGR2 is a system basis chip with high speed CAN transceiver. It is a monolithic integrated circuit combining many functions used by microcontroller (MCU) found in automotive Engine Control Units (ECUs). The device incorporates functions such as: two voltage regulators, four high-voltage (wake-up) inputs, a 1.0Mbaud capable CAN physical interface, an SPI interface to the MCU and VSUP monitoring and fault detection circuitry. It 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.
