NXP Semiconductors Document Number: MC33903 4 5 Rev. 14.0, 2/2018 Data Sheet: Advance Information SBC Gen2 with CAN high speed and 33903/ 33903/4/5 LIN interface The 33903/4/5 is the second generation family of the System Basis Chip (SBC). It combines several features and enhances present module designs. The device works as an advanced power management unit for the MCU with additional SYSTEM BASIS CHIP 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, one or two LIN 2.1 interfaces 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. 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 compatibility adds versatility to module design. EK Suffix (Pb-free) EK Suffix (Pb-free) 98ASA10556D 98ASA10506D The 33903/4/5 also implements an innovative and advanced fail-safe state 32-PIN SOIC 54-PIN SOIC machine and concept solution. Applications Features Voltage regulator for MCU, 5.0 or 3.3 V, part number selectable, with Aircraft and marine systems possibility of usage external PNP to extend current capability and share power Automotive and robotic systems dissipation Farm equipment Voltage, current, and temperature protection Industrial actuator controls Extremely low quiescent current in LP modes Lamp and inductive load controls Fully-protected embedded 5.0 V regulator for the CAN driver DC motor control applications requiring diagnostics Multiple undervoltage detections to address various MCU specifications and Applications where high-side switch control is system operation modes (i.e. cranking) required 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 supply, and critical pins diagnostics and monitoring. Multiple wake-up sources in LP modes: CAN or LIN bus, I/O transition, automatic timer, SPI message, and V overcurrent detection. DD ISO11898-5 high-speed CAN interface compatibility for baud rates of 40 kb/s to 1.0 Mb/s Scalable product family of devices ranging from 0 to 2 LINs which are compatible to J2602-2 and LIN 2.1 * This document contains certain information on a new product.
