33903/
33903/4/5
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 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.
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.
