Electrical and EMC/ESD confmance repts. Training material. Energy Management Ultra Low Power Modes Innovative Wake-up Event Scalable Power Supply Best-in-class quiescent current down to 15 µa including and wake-up active. Reduces contribution of active blocks during stand-by mode. Save time during cyclic check by reducing the number of state machine transitions. This contributes in reducing overall ECU energy consumption (Energy = Current x Time). Enables platfm solution (150 ma internal supply, up to 300 ma with an optional ballast transist). System Management Flexible Fail Safe Modes Secured Innovative Cranking Pulse Management Advanced Watchdog Ease Customer Debug Mode Flexibility to address the ECU functional safety assessment and program the default fail safe behavi via hardware implementation. Fast access higher frequency combined with new register addressing methodology to save time. Parity checks. System alternative to save customer cost (PCB space, cost of capacit) while keeping some degraded functionalities during cranking mode. Improved, safer and optional Watchdog (in addition to time-out and window watchdog) implemented to avoid unpredictable Watchdog recognition, so that closed loop MCU activity can be detected. The pin is used to inhibit the watchdog during debug mode. This helps hardware and software designers save time during application development. Robust Physical Layers Certification and Car OEM Approval Process and HS P/L meets confmance tests and EMC/ESD standard requirements to secure the customer design
