MCZ33905CD5EK

Specialized Overview

The MCZ33905CD5EK is a System Basis Chip (SBC) from the second-generation MC33905 family, designed for automotive body and powertrain applications. It integrates an enhanced High-Speed CAN interface compliant with ISO11898-2 and -5 standards, supporting data rates from 40 kB/s to 1.0 MB/s. The device features two LIN 2.1/J2602-2 interfaces and provides a configurable MCU voltage regulator (VDD) available in 5.0 V or 3.3 V options. It includes an auxiliary LDO regulator (VAUX), multiple wake-up sources, and advanced low-power modes with quiescent currents as low as 15 µA. The component operates within a supply voltage range of 5.5 V to 28 V and supports temperatures from -40 °C to 125 °C.

• Scalable power management with selectable 5.0 V or 3.3 V regulators
• Advanced fail-safe state machine linked to the SAFE pin

Specialized Applications

• Body Controller Modules
• Gateway Modules
• Seat Module Control
• Door Module and Lighting Control
• Engine Management Systems

Specialized Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm package type and electrical characteristics. Confirm RoHS compliance status and lead times directly with authorized distributors. Ensure the selected variant matches the required VDD output voltage and LIN interface configuration for the target application design.

Specialized Selection Notes

Select this model when dual LIN interfaces are required alongside High-Speed CAN connectivity. Compare the internal regulator current limits against system demands; utilize external ballast transistors if higher current capacity than the internal limit is necessary. Verify that the SOIC package dimensions fit the PCB layout constraints and thermal requirements of the enclosure.

Specialized Part Context

This component belongs to the MC33905 family of System Basis Chips, which serve as central power management units for microcontrollers in automotive networks. The 'D' designation indicates the inclusion of dual LIN interfaces, distinguishing it from single-LIN variants. These devices are engineered to reduce component count by integrating power regulation, communication interfaces, and diagnostic functions into a single package.

Specialized Replacement Considerations

Compatible replacements include other members of the MC33905 family such as MCZ33905BD5EK or MCZ33905BS5EK, depending on whether dual or single LIN interfaces are needed. Cross-reference pinouts and register maps to ensure software compatibility during migration.
