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.
- 128K EEPROM
- Wakeup from CAN interrupt
- External watchdog
- Secondary microprocessor
- 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
- 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
