MCZ33905DS3EKR2

The NXP Semiconductors MCZ33905DS3EKR2 is a second-generation System Basis Chip (SBC) that enhances module designs by integrating multiple features for advanced power management. It functions as an advanced power management unit for MCUs, incorporating integrated circuits for sensors and CAN transceivers.

This device features a high-speed CAN interface compliant with ISO11898-2 and -5, offering local and bus failure diagnostics, protection, and fail-safe operation modes. It also supports LIN 2.1 interfaces and includes up to four wake-up input pins that can be configured as output drivers for flexibility. Powered by SMARTMOS technology, the MCZ33905DS3EKR2 implements multiple low-power modes with very low current consumption.

Key electrical features include a selectable 5.0 V or 3.3 V voltage regulator for the MCU, a fully-protected embedded 5.0 V regulator for the CAN driver, and an auxiliary 5.0 V or 3.3 V SPI configurable regulator for additional ICs. It offers multiple undervoltage detections for various MCU specifications and system operation modes, such as cranking. Advanced diagnostics and monitoring are provided for SPI, MCU, ECU power supply, and critical pins.

The MCZ33905DS3EKR2 is available in a 32-SSOP exposed pad package suitable for surface mounting. Its operating voltage range is 5.5 V to 28 V, making it suitable for applications requiring robust power management and communication interfaces.
