• On-chip power-on-reset (POR), voltage detector (LVD) and key interrupt function (KIF)
• One 12-bit ADC 5 Msps, up to 16-bit with hardware oversampling
• One 16-bit advanced motor control timers
• One 32-bit timer
• One watchdog timer
• Operating temperature ranges between -40°C and 85°C
• Serial interfaces- CAN, UART, I2C, LIN, CSIs and IEBus
• Serial wire debug supported
• Supports up to 2 displays with WXGA resolution without the need of external memory
• Three separate power domains that can be independently clock-gated or switched off
