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

Annual Salary Survey

Before the calendar turned, 2016 already had the makings of a pivotal year for manufacturing, and for the world.

There were the big events for the year, including the United States as Partner Country at Hannover Messe in April and the 2016 International Manufacturing Technology Show in Chicago in September. There's also the matter of the U.S. presidential elections in November, which promise to shape policy in manufacturing for years to come.

But the year started with global economic turmoil, as a slowdown in Chinese manufacturing triggered a worldwide stock hiccup that sent values plummeting. The continued plunge in world oil prices has resulted in a slowdown in exploration and, by extension, the manufacture of exploration equipment.
