MCZ33903CP5EKR2

Specialized Overview

The MCZ33903CP5EKR2 is a second-generation System Basis Chip (SBC) from NXP Semiconductors, designed as an advanced power management unit for microcontrollers and integrated circuits. It integrates an enhanced high-speed CAN interface compliant with ISO11898-2 and -5 standards, featuring local and bus failure diagnostics. The device includes a configurable MCU voltage regulator (VDD) outputting 5.0 V or 3.3 V with a maximum current of 150 mA. It operates within a supply voltage range of 5.5 V to 28 V and withstands up to 40 V load dump. Key features include low-power modes with quiescent currents as low as 15 µA, secured SPI communication, and multiple wake-up sources.

Specialized Feature Summary

• Integrates an enhanced high-speed CAN transceiver with built-in diagnostic and protection capabilities.
• Provides a scalable MCU voltage regulator supporting both 5.0 V and 3.3 V outputs.
• Supports ultra-low power consumption in sleep modes to optimize energy efficiency.
• Includes secured SPI interface with watchdog functionality for reliable system monitoring.

Specialized Applications

• Body control modules
• Gateway systems
• Seat modules
• Door modules
• Lighting control modules

Specialized Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to ensure correct package type and temperature rating. Confirm RoHS compliance status prior to procurement. Check for any recent product change notices that may affect pin compatibility or electrical characteristics. Ensure the supplier provides valid traceability documentation for automotive-grade components.

Specialized Selection Notes

Select this component when a compact SBC solution with integrated high-speed CAN is required without LIN interfaces. The 150 mA internal regulator limits scalability compared to 'B' versions; consider external ballast transistors if higher current is needed. Verify that the 3-wake-up configuration meets the system's startup requirements. Ensure the operating temperature range aligns with the application environment.

Specialized Part Context

This part belongs to the MC33903/4/5 family of second-generation System Basis Chips. It is specifically the 'P' variant, which offers three configurable I/O pins configured for wake-up functions but lacks LIN interfaces. It serves as a cost-effective alternative to the 'S' and 'D' variants for applications requiring only CAN connectivity and basic power management.

Specialized Replacement Considerations

Direct replacements within the same family include MCZ33903BS5EK/R2 and MCZ33903CS5EK/R2, though these offer different wake-up/LIN configurations. Upgrading to 'B' versions like MCZ33903BD5EK/R2 provides improved oscillator performance and resolved slow ramp-up behavior. Ensure pin compatibility is verified before substitution.
