Features

include Active Reset circuitry watching VDDH, VDD3_3, VDDL and VKAM, user selectable Hardware Reset Timer (HRT), Power Sequencing circuitry guarantees the core supply voltages never exceed their limits or polarities during system power up and power down. A high speed CAN transceiver physical layer interfaces between the microcontroller CMOS outputs and differential bus lines. The CAN driver is short circuit protected and tolerant of loss of battery or ground conditions. 33394 is designed specifi.
