System Basis Chip with
High Speed CAN Transceiver
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 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.
Features
VDD1: Low drop voltage regulator, current limitation,
overtemperature detection, monitoring, and reset function
VDD1: Total current capability 200 mA
V2: Tracking function of VDD1 regulator. Control circuitry for external
bipolar ballast transistor for high flexibility in choice of peripheral
voltage and current supply
Low stand-by current consumption in Stop and Sleep modes
High speed 1.0 MBaud CAN physical interface
Four external high voltage wake-up inputs associated with HS1
VBAT switch
150 mA output current capability for HS1 VBAT switch allowing drive
of external switches pull-up resistors or relays
VSUP failure detection
40 V maximum transient voltage
