Advance Information
System Basis Chip with
High Speed CAN Transceiver
The MC33989 is a monolithic integrated circuit combining many functions
frequently used by automotive ECUs. It incorporates:
- Two voltage regulators.
- Four high voltage inputs.
- 1Mbaud CAN physical interface.
SYSTEM BASIS CHIP
WITH HIGH SPEED CAN
SEMICONDUCTOR
TECHNICAL DATA
• Vdd1: Low drop voltage regulator, current limitation, over temperature
detection, monitoring and reset function
• Vdd1: Total current capability 200mA.
• V2: Tracking function of Vdd1 regulator. Control circuitry for external bipolar
ballast transistor for high flexibility in choice of peripheral voltage and current
supply.
• Four operational modes (normal, stand-by, stop and sleep mode)
• Low stand-by current consumption in stop and sleep modes
• High speed 1MBaud CAN physical interface.
• Four external high voltage wake-up inputs, associated with HS1 Vbat switch
• 150mA output current capability for HS1 Vbat switch allowing drive of external
switches pull up resistors or relays
• Vsup failure detection
• Nominal DC operating voltage from 5.5 to 27V, extended range down to 4.5V.
• 40V maximum transient voltage
• Programmable software time out and window watchdog
• Safe mode with separate outputs for Watchdog time out and Reset
• Wake up capabilities (four wake up inputs, programmable cyclic sense,
forced wake up, CAN interface, SPI and stop mode over current)
• Interface with MCU through SPI
