Technical Data

System Basis Chip with

High-Speed CAN Transceiver

33989

The 33989 is a monolithic integrated circuit combining many

functions used by microcontrollers (MCU) found in automotive

Engine Control Units (ECUs). 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.
