MOTOROLA Order this document by Rev: 4.91 Date: 10th July, 2002 Freescale Semiconductor, Inc. SEMICONDUCTOR TECHNICAL DATA XC33989 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. 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) I...
