Product details
Overview
MCZ33905DS5EKR2 from NXP Semiconductors is a System Basis Chip (SBC) Gen2 integrating high-speed CAN (ISO 11898-2/5), single LIN 2.1 interface, 5.0 V MCU regulator, auxiliary 5.0 V regulator, four configurable wake-up/I/O pins, and fail-safe state machine - designed for automotive ECU power management and diagnostics in 12 V battery systems.
For engineers reviewing the MCZ33905DS5EKR2 datasheet, MCZ33905DS5EKR2 pinout, MCZ33905DS5EKR2 application, or MCZ33905DS5EKR2 equivalent, this page delivers verified technical context, real-world use cases, validated alternatives, and supply-chain support tailored to automotive embedded design, ECU diagnostics, and low-power vehicle networking.
Technical Context
The MCZ33905DS5EKR2 implements a SMARTMOS-based power management architecture with dual-supply inputs (VSUP1/VSUP2), integrated 5.0 V VDD regulator (±2% accuracy), and fully protected 5.0 V CAN driver supply. It supports ISO 11898-5 compliant CAN at baud rates from 40 kb/s to 1.0 Mb/s with bus fault diagnostics and fail-safe operation.
Its functional block includes an advanced SPI interface (16-bit command/response, 3.3/5.0 V tolerant), programmable wake-up sources (CAN/LIN activity, I/O transitions, SPI message, timer), and MUX-OUT analog monitoring of VDD, VSENSE, or internal temperature - all operating across LP modes with quiescent current as low as 20 µA (VDD ON).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CAN Interface | ISO 11898-2 and -5 compliant; enables robust 12 V automotive networking up to 1.0 Mb/s with local/bus failure detection. |
| LIN Interface | Single LIN 2.1 master interface with TXD-L/RXD-L pins and programmable LIN termination via LIN-T/I/O-2 pin. |
| VDD Regulator Output | 5.0 V ±2%, 250 mA capable; powers MCU directly; no external PNP support per datasheet Note 2. |
| Auxiliary Regulator | Configurable 5.0 V output (VAUX), with overcurrent detection and undervoltage protection for peripheral ICs. |
| Wake-up Inputs | Four configurable pins (I/O-0 to I/O-3); each supports edge-triggered wake-up in LP modes and HS/LS output drive. |
| Quiescent Current (LP) | 20 µA typical in VDD-ON LP mode; enables always-on ECU functions without battery drain. |
| Operating Temperature | -40 °C to +125 °C ambient; qualified for under-hood automotive applications per AEC-Q100. |
Pinout & Package

Key Features
| Feature | Design Value |
|---|---|
| Integrated Fail-Safe State Machine | Hardware-enforced safe state activation on VDD drop, watchdog timeout, or RST pin anomaly - independent of MCU firmware. |
| Multi-Source Wake-up in LP Modes | Simultaneous wake-up capability from CAN/LIN bus activity, I/O edge transitions, SPI message receipt, or internal timer - no MCU intervention required. |

Applications
| Body Control Module (BCM) | Door Module |
|---|---|
|
Use Scenario: Centralized control of lighting, window lifts, mirrors, and locks in modern vehicles. IC Role / Device Role / Timing Role: Primary SBC managing MCU power, CAN communication with gateway, LIN control of door actuators and sensors. Use Value: Reduces BOM by integrating CAN transceiver, 5.0 V regulator, wake-up I/Os, and failsafe logic - eliminating discrete protection and supervision ICs. |
Use Scenario: Local intelligence for power windows, central locking, and interior lighting in vehicle doors. IC Role / Device Role / Timing Role: LIN master coordinating multiple LIN slaves (switches, motors, sensors); provides regulated 5.0 V power and wake-up on key fob signal. Use Value: Enables ultra-low-power sleep (20 µA) while maintaining responsive wake-up via LIN or I/O-0–I/O-3 - extending battery life during vehicle standby. |
| Engine Control Unit (ECU) Subsystem | Advanced Driver Assistance Systems (ADAS) Sensor Hub |
|

Equivalent & Alternatives
The following parts are listed as comparable options for similar System Basis Chip applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCZ33905DS3EKR2 | Same 32-pin SOIC package and pinout; differs only in VDD output voltage (3.3 V vs. 5.0 V). | Used where MCU requires 3.3 V supply instead of 5.0 V; VAUX remains configurable at 3.3 V or 5.0 V. | Select when interfacing with 3.3 V MCUs; verify external level-shifting for CAN/LIN if required. |
| MCZ33904D5EKR2 | No LIN interface; zero LIN channels; retains same CAN, regulators, wake-up I/Os, and 5.0 V VDD output. | Targeted at CAN-only ECUs (e.g., simple body modules without LIN peripherals); lower cost and reduced feature set. | Choose when LIN is unnecessary - reduces software complexity and eliminates LIN termination configuration overhead. |
Compared with MCZ33905DS5EKR2, MCZ33905DS3EKR2 offers identical functionality at 3.3 V for low-voltage MCUs, while MCZ33904D5EKR2 removes LIN entirely for simplified CAN-centric designs - both share footprint compatibility and diagnostic architecture but differ in voltage and interface scope.

FAQ
What is the maximum CAN baud rate supported by MCZ33905DS5EKR2?
MCZ33905DS5EKR2 supports high-speed CAN up to 1.0 Mb/s, compliant with ISO 11898-5 for partial networking and ISO 11898-2 for standard high-speed operation. This enables full integration into modern automotive CAN FD gateways and domain controllers without external transceivers.
Does MCZ33905DS5EKR2 support external PNP transistor for VDD current extension?
No, MCZ33905DS5EKR2 does not support external PNP transistor for VDD current extension. Per datasheet Note 2, this capability is explicitly excluded for the 33903 series and applies only to 33905/33904 variants with "D" version and non-33903 part numbers - but even then, VDD PNP support is not implemented in MCZ33905DS5EKR2.
How many wake-up sources does MCZ33905DS5EKR2 provide in low-power mode?
MCZ33905DS5EKR2 provides four dedicated wake-up sources: CAN bus activity, LIN bus activity, I/O pin transitions (on I/O-0 to I/O-3), SPI message reception, and internal automatic timer expiration - all operable simultaneously in VDD-ON low-power mode.
What is the function of the MUX-OUT pin on MCZ33905DS5EKR2?
The MUX-OUT pin on MCZ33905DS5EKR2 is a multiplexed analog output that allows the MCU to monitor internal parameters - including VDD voltage, battery voltage (VSENSE), die temperature, or internal reference - via a single ADC channel, reducing external sensing components and PCB routing complexity.
Is MCZ33905DS5EKR2 pin-compatible with other devices in the 33903/4/5 family?
Yes, MCZ33905DS5EKR2 is pin-compatible with MCZ33905DS3EKR2, MCZ33904D5EKR2, and MCZ33903DS5EKR2 within the 32-pin SOIC (SOT1746-3) package variant - enabling flexible design reuse across LIN-count and VDD-voltage variants without PCB redesign.
