MPC5668G Evaluation Board
The MPC5668 evaluation board (hereinafter referred to as EVB) provides a simple method for customer evaluation of MPC5668 series microcontrollers, and can promote hardware and software development.
The MPC5668 series adopts 208MAPBGA package. The 256MAPBGA package that supports Nexus debugging can also be used for development.
EVB is mainly for test benches/laboratories and has adopted the normal temperature specified by the components. (+70°C). Main features of MPC5668G evaluation board
EVB provides the following main features:
• MCU socket supports 208BGA production package and 256BGA development package
•The separate 12V~14V external power input using the on-board debugger provides all the required EVB and MCU voltages. Power can be supplied through a 2.1mm cylindrical power socket and 2-way connector. If necessary, in the car 12V operating voltage can be used inside
• Flexible on-board power supply configuration, if necessary, you can choose to bypass the internal MCU regulator
• Main power switch and regulator status LED—The regulator is connected to the ADC to allow monitoring.
• User reset conversion using reset status LED
• User-configurable low voltage suppression to monitor the status of 3.3V and 5V regulators
• Control the BOOTCFG state through a dedicated jumper
• Flexible MCU clock options
– 40MH oscillator crystal
– 32Khz clock crystal oscillator
