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 combines 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 compatibility 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.
