OpenECU M210


The M250 module is a compact electronics module that is suited to computationally intensive applications requiring a chassis mounted, sealed metal housing with IP67 environmental protection.

Based on the same Freescale MPC5534 32-bit microcontroller as the M460, the M250 features 2 CAN interfaces, precision analogue 12-bit inputs and configurable high current switching outputs. A group of inputs and outputs are particularly suited emissions control applications with appropriate sensor signal conditioning and drive characteristics.

OPTIONAL CAPABILITIES

  • 128K EEPROM
  • Wakeup from CAN interrupt
  • External watchdog
  • Secondary microprocessor


TYPICAL APPLICATIONS

  • Diesel exhaust after-treatment control
  • Chassis control
  • Computationally intensive ancillary controls
  • Control with high current switching capability
  • Diesel engine management when coupled with the  S070   slave fuel injection driver  
     

DEVELOPMENT TOOLS

  • Simulink™/RTW based development platform
  • Simulink™ RTW-Embedded Coder blockset, as well as a C API function library to support C-language implementation of code (or TargetLink™)
  • Reprogramming via CAN using CCP
  • Calibration: ATI Vision™ or ETAS INCA™
  • Processor JTAG port accessible internally
