MCZ33905DD5EK

The NXP Semiconductors MCZ33905DD5EK is a System Basis Chip (SBC) featuring CAN and LIN interfaces, designed for automotive and system basis chip applications. This specialized interface IC operates within a wide voltage range of 5.5V to 28V and maintains functionality across an operating temperature range of -40°C to 125°C.

This device integrates advanced power management capabilities for MCUs, along with additional circuits for sensors and CAN transceivers. It supports high-speed CAN interfaces compliant with ISO11898-2 and -5, offering diagnostics, protection, and fail-safe modes. The SBC may also include LIN 2.1 interfaces and multiple wake-up inputs configurable as output drivers. It is built using SMARTMOS technology and offers multiple low-power modes with very low current consumption.

The MCZ33905DD5EK is supplied in a 54-SSOP package with an exposed pad, requiring surface mount installation. Its robust design includes voltage, current, and temperature protection, multiple undervoltage detections, and an auxiliary SPI configurable regulator with overcurrent detection.

Key features include a fully-protected embedded 5.0 V regulator for the CAN driver and advanced diagnostics for SPI, MCU, ECU power supply, and critical pins. It supports various wake-up sources, including CAN or LIN bus transitions, I/O transitions, automatic timers, SPI messages, and VDD overcurrent detection.
