Product details
Overview
MCZ33905DS5EK from NXP Semiconductors is a System Basis Chip (SBC) Gen2 integrating a 5.0 V MCU power regulator, high-speed CAN transceiver (ISO 11898-2/5), single LIN 2.1 interface, four configurable wake-up/I/O pins, and SPI diagnostics - designed for automotive ECU power management in 12 V battery systems.
For engineers reviewing the MCZ33905DS5EK datasheet, MCZ33905DS5EK pinout, MCZ33905DS5EK application, or MCZ33905DS5EK equivalent, this device delivers fail-safe state machine control, ultra-low quiescent current in LP modes, integrated CAN bus fault diagnostics, and MUX-based analog monitoring for robust ECU design validation and functional safety compliance.
Technical Context
The MCZ33905DS5EK implements a SMARTMOS-based power management architecture with dual supply inputs (VSUP1/VSUP2), a dedicated 5.0 V CAN regulator, and configurable LIN termination via LIN-T/I/O-2 and LIN-T2/I/O-3 pins. Its fail-safe state machine monitors VDD, RST, watchdog timeout, and CAN/LIN activity to assert SAFE (active-low) on fault detection.
It supports ISO 11898-5 high-speed CAN at baud rates from 40 kb/s to 1.0 Mb/s and LIN 2.1 at up to 20 kb/s, with cyclic sense capability during low-power modes and SPI-controlled register access for real-time diagnostics of voltage, current, temperature, and bus status.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDD Output | 5.0 V ±2%, supplies MCU core logic with external PNP support disabled per datasheet note. |
| CAN Interface | ISO 11898-2 and -5 compliant, supports 40 kb/s–1.0 Mb/s, includes bus fault diagnostics and fail-safe operation. |
| LIN Interface | Single LIN 2.1 channel with TXD-L/RXD-L pins and programmable master termination on LIN-T/I/O-2. |
| Wake-up Inputs | Four configurable I/O pins (I/O-0 to I/O-3), each usable as wake source via CAN, LIN, timer, SPI, or edge transition. |
| LP Mode Current | <20 µA typical in VDD-off LP mode; <70 µA in VDD-on LP mode - enables extended battery life in always-on ECUs. |
| MUX Monitoring | Configurable analog multiplexer output (MUX-OUT) for SPI-selected parameters: VDD, VSUP, VSENSE, temperature, or current sense. |
| Package | 32-pin SOIC exposed pad (SOT1746-3), Pb-free, rated for −40 °C to +125 °C ambient operation. |
Pinout & Package
MCZ33905DS5EK uses a 32-pin SOIC exposed pad package (SOT1746-3) with thermal pad connected to GND for enhanced thermal performance in automotive under-hood environments.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VSUP1 | Battery Supply Input | Main battery input (−0.3 V to 28 V DC) powering internal regulators, POR, and VDD circuitry. |
| VSUP2 | Secondary Supply Input | Input for 5V-CAN, VAUX, and I/O/LIN drivers; internally tied to VSUP1 in this variant. |
| VDD | MCU Power Output | 5.0 V regulated output (±2%) for microcontroller core; no external PNP support per datasheet. |

| I/O-0 to I/O-3 | Flexible I/O Pins | Four bidirectional pins supporting wake-up, cyclic sense, HS switching, or analog monitoring via MUX-OUT. |
| SAFE | Fault Indicator | Open-drain active-low output signaling fail-safe condition (e.g., VDD undervoltage, watchdog timeout). |
| MUX-OUT | Analog Monitor Output | SPI-selectable analog output for VDD, VSUP, VSENSE, die temp, or current sense - enables MCU ADC monitoring. |
| SPI Pins (CS/SCLK/MOSI/MISO) | Configuration Interface | 4-wire SPI for register read/write, diagnostics, and mode control with interrupt-driven status reporting. |
Key Features
| Feature | Design Value |
|---|---|
| Fail-Safe State Machine | Hardware-enforced state transitions with SAFE pin assertion on VDD loss, RST fault, watchdog timeout, or CAN/LIN error escalation. |
| Multi-Source Wake-up | Four independent wake sources: CAN/LIN bus activity, I/O edge, SPI message, automatic timer, or VDD overcurrent detection. |
| Integrated CAN Diagnostics | Real-time bus fault detection (short-to-battery/ground, open, dominant timeout) with SPI-reportable status flags. |
| Configurable LIN Termination | LIN-T/I/O-2 pin supports software-selectable 1 kΩ termination for LIN master node - eliminates external resistor. |
| Low-Power Operation | Two LP modes: VDD-off (<20 µA) and VDD-on (<70 µA); retains SPI accessibility and wake-up responsiveness. |
Applications
| Body Control Module (BCM) | Door Module |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar System Basis Chip applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCZ33905DS3EK/R2 | Same 32-pin SOIC package and feature set, but delivers 3.3 V VDD output instead of 5.0 V. | Required where MCU requires 3.3 V supply; not suitable for 5 V logic or legacy peripherals. | Select only if target MCU operates at 3.3 V and external level-shifting is unavailable. |
| MCZ33904D5EK/R2 | Omits LIN interface entirely; retains 5.0 V VDD, CAN, four wake-up I/Os, and MUX monitoring. | Targeted at CAN-only nodes (e.g., gateway modules) without LIN slave connectivity requirements. | Choose when LIN is unnecessary - reduces software stack complexity and eliminates LIN termination configuration overhead. |
Compared with MCZ33905DS3EK/R2 and MCZ33904D5EK/R2, the MCZ33905DS5EK uniquely balances 5.0 V MCU supply, single-LIN capability, and full diagnostic coverage in a compact 32-pin footprint - making it optimal for cost-sensitive, space-constrained automotive body electronics requiring both CAN and LIN interoperability.

FAQ
What is the maximum CAN baud rate supported by the MCZ33905DS5EK?
The MCZ33905DS5EK supports high-speed CAN at baud rates from 40 kb/s up to 1.0 Mb/s, fully compliant with ISO 11898-2 and ISO 11898-5 standards. This range accommodates both legacy CAN FD preambles and standard CAN 2.0B timing requirements in automotive networks.
Does the MCZ33905DS5EK support external PNP transistor boosting for the VDD regulator?
No, the MCZ33905DS5EK does not support external PNP transistor boosting for the VDD regulator. Per datasheet Note 2 in Table 3, external PNP usage is explicitly prohibited for all MC33903 variants and not enabled for MC33905D/S variants - VDD is fixed at 5.0 V with internal regulation only.
How many wake-up sources does the MCZ33905DS5EK provide, and what are they?
The MCZ33905DS5EK provides four dedicated wake-up capable pins (I/O-0 to I/O-3), plus additional wake sources including CAN bus activity, LIN bus activity, SPI message reception, automatic timer expiration, and VDD overcurrent detection - enabling flexible low-power system architecture.
What is the function of the MUX-OUT pin on the MCZ33905DS5EK?
The MUX-OUT pin on the MCZ33905DS5EK is a configurable analog output that routes selected internal signals - including VDD, VSUP, VSENSE, die temperature, or current sense voltage - to an MCU's ADC input via SPI register control, enabling real-time health monitoring without external components.
Is the MCZ33905DS5EK pin-compatible with other devices in the 33903/4/5 family?
Yes, the MCZ33905DS5EK shares the same 32-pin SOIC exposed pad (SOT1746-3) footprint with MCZ33905DS3EK/R2, MCZ33904D5EK/R2, and MCZ33903DS5EK/R2 - enabling hardware reuse across variants differing only in VDD voltage, LIN count, or auxiliary features.
