The G850D is a high performance electronics module particularly suited to multi-cylinder (up to 8) gasoline engine management applications. It is supplied in a chassis mount, extremely rugged, sealed metal housing with IP65 environmental protection.
Based on the Freescale MPC565 32-bit microcontroller the G850D features CAN interface and 66 standard input/output functions via one 70-way and two 50-way connectors. This product has been in volume production for many years, and in a very wide range of applications.
- Lower cost fleet version with on-the-fly calibration memory module removed (G850F)
- Engine control (up to 8 cylinders)
- Complex diesel exhaust after-treatment control
- Complex chassis control
- Transmission control
- Ancillary function control
- Computationally intensive ancillary controls with high I/O
- Complex control with high current switching capability
- Simulink™/RTW based development platform
- C API function library to support C-language implementation of code (or TargetLink™)
- Simulink™ RTW-Embedded Coder blockset
- Reprogramming via CAN using CCP
- Calibration: ATI Vision™ or ETAS INCA™
