MC34903CS5EK Datasheet | Freescale Semiconductor

Freescale Semiconductor Technical Data Document Number: MC34903_4_5 Rev. 4.0, 10/2013 System Basis Chip with CAN High Speed and LIN Interface I3n34d49u90s03t3/r4/i/a5l The 34903/4/5 is the second generation family of the System Basis Chip (SBC). It bines several Features and enhances present module designs. The device works as an advanced power management unit for the MCU with additional integrated circuits such as sensors and CAN transceivers. It has a built-in enhanced high-speed CAN interface (ISO11898-2 and -5) with local and bus failure diagnostics, protection, and fail-safe operation modes. The SBC may include zero or one LIN 2.1 interface with LIN output pin switches. It includes up to four wake-up input pins that can also be configured as output drivers for flexibility. This device is powered by SMARTMOS technology. SYSTEM BASIS CHIP This device implements multiple Low-power (LP) modes, with very low-current consumption. In addition, the device is part of a family concept where pin patibility adds versatility to module design. EK Suffix (Pb-free) 98ASA10556D 32-PIN SOIC The 34903/4/5 also implements an innovative and advanced fail-safe state machine and concept solution. Applications Features - Industrial process control - Voltage regulator for MCU, 5.0 or 3.3 V, part number selectable, with possibility of usage external PNP to extend current capability and share power dissipation - Voltage, current, and temperature protection - Automation - Motor control - Robotics - Extremely low quiescent current in LP modes - Fully-protected embedded 5.0 V regulator for the CAN driver - Multiple undervoltage detections to address various MCU specifications and system operation modes (i.e. cranking) - Auxiliary 5.0 or 3.3 V SPI configurable regulator, for additional ICs, with overcurrent detection and undervoltage protection - MUX output pin for device internal analog signal monitoring and power supply monitoring - Advanced SPI, MCU, ECU power...
