System Basis Chip with High Speed CAN Transceiver

The 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 1.0 Mbaud 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.

Table 1. 33989 Pin Definitions A functional description of each pin can be found in the Functional Pin Description section beginning on page 18.
Voltage Digital Drain 5.0 V regulator output pin. Supply pin for the MCU.

This is the device reset output pin whose main function is to reset the MCU. This pin has an internal pullup current source to VDD.
This output is asserted LOW when an enabled interrupt condition occurs.

These device ground pins are internally connected to the package lead frame to provide a 33989-to-PCB thermal path.

Sense input for the V2 regulator using an external series pass transistor. V2 is also the internal supply for the CAN transceiver.
Output drive source for the V2 regulator connected to the external series
Output of the internal high side switch. The output current is internally
Level 0: 3 CAN High CAN Low System Clock Master In/Slave Out

Inputs from external switches or from logic circuitry. CAN high output pin. CAN low output pin. Clock input pin for the serial peripheral interface (SPI). SPI data sent to the MCU by the 33989. When CS is HIGH, the pin is in the high-impedance state.
