Product details
Overview
MCZ33903DP5EKR2 from NXP Semiconductors is a System Basis Chip (SBC) Gen2 integrating high-speed CAN (ISO 11898-2/5), 5.0 V MCU supply regulator, three wake-up inputs, and fail-safe state machine for automotive ECU power management. It operates from VSUP = −0.3 to 28 V, supports baud rates up to 1.0 Mb/s, and delivers <100 µA quiescent current in LP modes. Used in lamp controls, DC motor systems, and industrial actuators requiring diagnostics.
For engineers reviewing the MCZ33903DP5EKR2 datasheet, MCZ33903DP5EKR2 pinout, MCZ33903DP5EKR2 application, or MCZ33903DP5EKR2 equivalent, this page provides verified technical context, real-world design meaning of key specs, validated pin functions, and confirmed alternative parts for automotive embedded power management with CAN/LIN interface requirements.
Technical Context
The MCZ33903DP5EKR2 implements a SMARTMOS-based fail-safe state machine with watchdog supervision, SPI-configurable LP modes, and integrated diagnostics for VDD, CAN bus, and I/O pins. Its CAN interface complies with ISO 11898-5 for partial networking and includes local/bus fault detection and fail-safe operation.
It features a 5.0 V fixed-output VDD regulator (no external PNP support), no LIN transceivers, no VAUX/VSENSE/MUX-OUT functionality per datasheet Table 3, and uses three wake-up–capable I/O pins (I/O-0, I/O-2, I/O-3) configured as high-side switches or digital inputs. The device shares SOIC-32 exposed-pad footprint (SOT1762-2) with other MC33903 variants.

FAQ
What is the VDD output voltage of the MCZ33903DP5EKR2?
The MCZ33903DP5EKR2 provides a fixed 5.0 V output on the VDD pin for powering the connected microcontroller. Unlike some variants in the MC33903 family, this part does not support external PNP transistor augmentation for increased current capability, as explicitly stated in the datasheet footnote for the 'D' version.
Does the MCZ33903DP5EKR2 support LIN communication?
No, the MCZ33903DP5EKR2 does not include any LIN transceiver functionality. Per Table 3 of the datasheet, it is the "P" variant (zero LIN interfaces), distinguishing it from DS5 (single LIN) and DD5 (dual LIN) versions. Its I/O pins (I/O-0, I/O-2, I/O-3) are configurable as wake-up inputs or high-side switches but not LIN drivers.
What wake-up sources are available on the MCZ33903DP5EKR2?
The MCZ33903DP5EKR2 supports three dedicated wake-up–capable pins: I/O-0, I/O-2, and I/O-3. Each can be configured as a digital input to detect edge transitions in low-power modes. Additionally, wake-up can be triggered by CAN bus activity, SPI messages, or internal timer events-all managed by the integrated fail-safe state machine.
What is the maximum supply voltage rating for the MCZ33903DP5EKR2?
The MCZ33903DP5EKR2 has a maximum continuous supply voltage rating of 28 V on the VSUP pin, with transient tolerance up to 40 V under load-dump conditions per Table 5 in the datasheet. This rating ensures reliable operation in 12 V and 24 V automotive electrical systems subject to ISO 7637-2 pulses.
Is the MCZ33903DP5EKR2 pin-compatible with other MC33903 variants?
Yes, the MCZ33903DP5EKR2 uses the SOIC-32 exposed-pad package (SOT1762-2) and shares identical pinout and footprint with MCZ33903DS5EKR2 and MCZ33903DD5EKR2. This allows direct PCB reuse across P/D/S/DD variants when only functional differences (e.g., LIN count, VSENSE presence) need updating via firmware or minor component changes.
