STMicroelectronics (Geneva, Switzerland) introduces the L99PM72PXP, an automotive IC supporting advanced networking technology to unlock valuable improvements in fuel efficiency and emissions. The new chip reduces the energy consumed by systems such as door electronics and climate controls by allowing modules to be turned off individually when not being used.
This feature could reduce an average vehicle's CO2 emission by more than 2 g/km.
By integrating both High-Speed CAN (HS-CAN) and LIN physical layers, L99PM72PXP provides all the functions needed to build up a complete Electronic Control Unit (ECU) for car body applications. Unlike standard CAN transceivers or system-basis chips currently on the market, the L99PM72PXP is able to monitor the CAN bus autonomously, without the module’s main processor being active. It activates the module only when a correctly addressed wake-up signal is detected. By allowing parts of the CAN network to be deactivated in this way, the L99PM72PXP contributes to reduce overall electrical energy consumption.
