Product details
Overview
MCZ33904D3EK from NXP Semiconductors is a System Basis Chip (SBC) Gen2 integrating a 3.3 V MCU power regulator, high-speed CAN transceiver (ISO 11898-2/5 compliant), four programmable wake-up inputs, and analog monitoring via MUX-OUT. It operates in ultra-low-power modes with <10 µA quiescent current and supports automotive ECU power management in harsh environments.
For engineers reviewing the MCZ33904D3EK datasheet, MCZ33904D3EK pinout, MCZ33904D3EK application, or MCZ33904D3EK equivalent, this device serves as a complete power + communication hub for microcontroller-based automotive modules requiring fail-safe operation, bus diagnostics, and flexible I/O wake-up control under -40 °C to +125 °C conditions.
Technical Context
The MCZ33904D3EK implements a SMARTMOS-based fail-safe state machine with dedicated SAFE output assertion on VDD undervoltage, watchdog timeout, or RST pin fault. Its integrated CAN physical layer supports baud rates from 40 kb/s to 1 Mb/s and includes local/bus failure diagnostics, short-to-battery/ground detection, and fail-safe mode entry without MCU intervention.
This variant belongs to the 33903/4/5 family's "D" revision - recommended for new designs - with resolved oscillator stability, improved current consumption, and no SPI errata. Unlike MC33903 variants, MCZ33904D3EK provides VAUX, VSENSE, and MUX-OUT functionality while omitting LIN interfaces entirely.
Key Specifications

| MUX-OUT | Analog multiplexed output | SPI-selectable analog signal (VDD, VSUP1, VSUP2, VSENSE, die temp); includes internal pull-down for current sensing |
| SAFE | Failsafe status output | Open-drain active-low signal asserting on critical faults (VDD UV, watchdog timeout, RST anomaly) |
| INT | Interrupt output | Open-drain interrupt flag for SPI-accessible events (CAN error, wake-up, regulator fault, etc.) |
Key Features
| Feature | Design Value |
|---|---|
| Fail-safe state machine | Dedicated hardware logic that asserts SAFE pin and enters defined safe state without MCU involvement during critical failures |
| Multi-level undervoltage detection | Independent thresholds for VDD, VSUP1, VSUP2, and VSENSE - supports cranking, sleep, and run-mode voltage monitoring |
| Embedded 5 V-CAN regulator | Internally regulated 5 V supply for CAN transceiver - eliminates need for external LDO and improves noise immunity |
| Cyclic sense in LP mode | I/O-0 and I/O-1 can operate as synchronized HS/LS drivers during low-power cyclic sense - enables load diagnostics without waking MCU |
| Diagnostic SPI interface | Full register access for real-time monitoring of CAN bus status, regulator health, temperature, and I/O states - supports functional safety compliance |

Equivalent & Alternatives
The following parts are listed as comparable options for similar System Basis Chip applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCZ33904D5EK | Same pinout and feature set, but delivers 5.0 V VDD output instead of 3.3 V; no change to CAN, wake-up, or MUX capabilities | Required when interfacing with 5 V MCU families or legacy peripherals needing 5 V logic levels | Select MCZ33904D5EK if target MCU requires 5 V supply; otherwise MCZ33904D3EK is optimal for 3.3 V systems |
| MCZ33903DP3EK | 32-pin SOIC package, 3.3 V VDD, zero LIN interfaces, three wake-up inputs (vs. four), no VSENSE or VAUX outputs | Lacks VSENSE, VAUX, and one wake-up pin - suitable for simpler ECU nodes where full monitoring is not required | Choose MCZ33903DP3EK only when reduced feature count and lower cost outweigh need for VSENSE/MUX-OUT diagnostics |
Compared with MCZ33904D3EK, MCZ33904D5EK offers identical functionality at 5 V output, while MCZ33903DP3EK sacrifices one wake-up input and key monitoring features (VSENSE, VAUX) to reduce complexity - making MCZ33904D3EK the balanced choice for full-featured 3.3 V automotive SBC applications.

FAQ
What is the primary function of the MCZ33904D3EK in an automotive ECU?
The MCZ33904D3EK serves as a System Basis Chip that integrates MCU power regulation (3.3 V), high-speed CAN transceiver (ISO 11898-2/5), four wake-up inputs, analog monitoring via MUX-OUT, and fail-safe SAFE output. It replaces discrete power, interface, and supervision components in automotive ECUs, reducing board space and improving system reliability. The MCZ33904D3EK enables deterministic low-power operation and real-time diagnostics without MCU intervention.
Does the MCZ33904D3EK support LIN communication?
No, the MCZ33904D3EK does not include any LIN interface functionality. According to NXP's orderable part table and internal block diagram, this variant is explicitly designated as the "0 LIN" configuration within the 33903/4/5 family. Its pinout omits all LIN-related signals (RXD-L, TXD-L, LIN-T), and the datasheet confirms LIN capability is present only in MC33903D/S/P and MC33905D/S variants. The MCZ33904D3EK focuses exclusively on CAN and power management.
What are the key differences between MCZ33904D3EK and MCZ33903DP3EK?
The MCZ33904D3EK provides four wake-up inputs, VSENSE, VAUX, and MUX-OUT functionality, while MCZ33903DP3EK offers only three wake-up inputs and excludes VSENSE and VAUX. Both use the same 32-pin SOIC package and 3.3 V VDD output, but MCZ33904D3EK supports more comprehensive system monitoring. The MCZ33904D3EK also includes enhanced CAN diagnostics and failsafe behavior per Gen2 architecture - features confirmed in its dedicated functional description section.
Can the MCZ33904D3EK's VDD output be increased beyond 3.3 V using external components?
Yes, the MCZ33904D3EK's 3.3 V VDD output can be extended in current capability using an external PNP transistor configured in series with the internal regulator - as documented in the "Voltage regulator for MCU" feature list. The VB and VE pins provide base drive and emitter connection points for this external pass transistor. However, the output voltage remains fixed at 3.3 V; it cannot be adjusted to a different nominal value without modifying the internal reference.
Is the MCZ33904D3EK pin-compatible with other devices in the 33903/4/5 family?
Yes, the MCZ33904D3EK uses the 32-pin SOIC exposed pad package (SOT1746-3) and shares identical pinout and footprint with MC33905S, MC33903D, MC33903S, and MC33903P - as confirmed in Figure 11 and Table 4 of the datasheet. This allows design reuse across family variants. However, functional differences exist: MCZ33904D3EK lacks LIN pins present in MC33905S/MC33903D, and its I/O-2/I/O-3 pins are dedicated wake-up inputs rather than LIN termination outputs.
