System basis chips provide energy efficiency and safety for in-vehicle networks

Freescale's latest generation of automotive certified CAN/LIN devices meet electromagnetic compatibility requirements.

03/05/2010


FreescaleSemiconductor has released its next generation of system basis chips (SBCs) whichintegrate an energy management module to power microcontrollers (MCUs),transceiver interfaces to connect with in-vehicle networks, and low-power modesto conserve battery life.

The

MC33904/5S/5D SBCs are built on Freescale SmartMOS technology and are designed

to optimize the performance, power consumption, and cost of electronic control

units for a range of automotive applications. The devices are also suitable for

high-performance body applications such as body controlmodules, lighting

modules, door/seat modules, seatbelt pretensioners, fuel/water pumps, glow plugs,

and low-end engine management systems. They can also be used in applications

including safety and powertrain.

EMC

and electrostatic discharge (ESD) are a serious concern in harsh automotive

environments due to the close proximity of networked electronic systems and

devices. These CAN/LIN-certified devices offer programmable fail-safe features

to assist with system functional safety, while providing a high-level of ESD

protection and EMC performance to address stringent automotive requirements.

The SBCs are AEC-Q100 automotive qualified and are reported to be immune to EMC

and ESD stresses without the need for external components, simplifying the bill

of materials.

Power

management scalability features include:

  • MCU power supply (Vdd):5-volt or 3.3/150mA (with split power option up to 300mA)
  • 5V or 3.3V Vreg forauxiliary loads
  • Dedicated 5V Vreg for CANhigh-speed


Functionalsafety features include:

  • Cranking pulse managementduring low Vdd
  • Fail-EMC safe andconfigurable state machine
  • Enhanced protections anddiagnostics


Energysavings features include:

  • Ultra-low-power modes(typical 15uA with Vdd off)
  • Wake-up management andcyclic sense


Physicallayer features include:

  • Certification to LIN 2.1 andISO 11898-2-5 standards
  • Certification to EMC, ISO,ESD standards
