MCZ33903CP3EK

Specialized Overview

The MCZ33903CP3EK is a System Basis Chip (SBC) from the MC33903 family, designed for automotive applications. It integrates an MCU voltage regulator and a high-speed CAN transceiver with LIN interface capabilities. The device operates within an input voltage range of 5.5 V to 28 V. It features two LDOs providing 400 mA output current each, with configurable output voltages. The component supports multiple wake-up sources including CAN, LIN, I/O transitions, and SPI messages. It includes comprehensive protection mechanisms such as over-current, under-voltage, and temperature monitoring. The chip is housed in a SOIC-32 package and functions as an advanced power management unit for microcontrollers.

Specialized Feature Summary

• Integrates an enhanced high-speed CAN interface with local and bus failure diagnostics
• Provides flexible wake-up sources in low-power modes via CAN, LIN, or I/O transitions
• Includes fully protected embedded regulators with over-current and under-voltage detection

Specialized Applications

• Automotive electronic control units (ECUs)
• Body control modules
• Gateway modules requiring CAN and LIN communication

Specialized Procurement Notes

Verify the specific suffix 'P3' against official NXP documentation to confirm pinout and regulatory compliance details. Ensure the ordering part number matches the required packaging format, such as tube or reel, as indicated in the manufacturer's datasheet. Confirm RoHS status and humidity sensitivity handling requirements prior to procurement.

Specialized Selection Notes

Select this SBC when a combined solution for MCU power supply and CAN/LIN communication is required. Consider the integrated diagnostic features and low quiescent current in low-power modes. Verify that the available wake-up sources meet the system's sleep and resume requirements. Ensure the thermal performance of the SOIC-32 package suits the application's power dissipation needs.

Specialized Part Context

This component belongs to the second-generation MC33903/4/5 System Basis Chip family. It serves as an evolution of previous SBC designs by combining power management with communication interfaces. The family targets automotive systems needing robust power regulation and reliable data communication in a single package.

Specialized Replacement Considerations

Check for direct substitutes within the MC33903 family, such as variants with different LDO configurations or wake-up options. Verify pin-to-pin compatibility and electrical parameter equivalence before substitution.
