Product details
Overview
MCZ33905CD5EKR2 from NXP (formerly Freescale) is a second-generation System Basis Chip (SBC) integrating high-speed CAN, dual LIN transceivers, and power management for automotive ECUs. It delivers 5.0 V / 300 mA MCU supply (VDD), internal 5.0 V CAN regulator (VCAN), and configurable wake-up I/Os in a 54-pin SOIC exposed-pad package. Used in body control modules, seat modules, and HVAC systems requiring ISO 11898-2/5 and LIN 2.1 compliance.
For engineers reviewing the MCZ33905CD5EKR2 datasheet, MCZ33905CD5EKR2 pinout, MCZ33905CD5EKR2 application, or MCZ33905CD5EKR2 equivalent, key selection criteria include dual-LIN support with flexible I/O wake-up configuration, ultra-low 15 µA sleep current with active CAN/LIN wake capability, fail-safe state machine linkage to SAFE pin, and integrated VSUP sensing with MUX analog monitoring.
Technical Context
The MCZ33905CD5EKR2 implements an advanced fail-safe state machine tied to the SAFE pin, enabling configurable degraded operation during fault conditions. Its dual LIN 2.1/J2602-2 interfaces support data rates up to 20 kB/s (100 kB/s fast mode), while the enhanced high-speed CAN physical layer complies with ISO 11898-2 and -5, supporting 40 kB/s to 1 MB/s.
Power architecture includes three independent regulators: 5.0 V VDD (300 mA with optional external PNP), 5.0 V VCAN for CAN transceiver supply, and configurable VAUX (5.0/3.3 V). Wake-up inputs are software-configurable as LIN master terminations, supporting up to two LIN terms plus two wake-up pins-or four wake-up-only pins-within the same pinout.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDD Output Voltage | 5.0 V ±2%, supports MCU core supply with up to 300 mA output using optional external ballast transistor |

Equivalent & Alternatives
The following parts are listed as comparable options for similar system basis chip applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCZ33905BD5EKR2 | Same 54-pin SOIC package and dual-LIN functionality; "B" revision resolves VSUP slow ramp-up behavior and improves oscillator stability | Identical use cases but preferred for new designs due to enhanced startup reliability and lower sleep current | Select MCZ33905BD5EKR2 when designing new platforms requiring validated startup behavior and improved ESD immunity |
| TJA1145ATK/0Z | Single high-speed CAN transceiver with embedded voltage regulator (no LIN); smaller 32-pin HVQFN package; no analog MUX or configurable wake I/O | Targeted at CAN-only gateways or simple ECU nodes where LIN is handled externally | Choose TJA1145ATK/0Z only if LIN functionality is implemented separately and board space is constrained |
Compared with MCZ33905CD5EKR2, the MCZ33905BD5EKR2 offers verified improvements in VSUP ramp-up and oscillator jitter-critical for cold-cranking robustness-while the TJA1145ATK/0Z provides CAN-only functionality in a compact footprint but requires external LIN and power management components.

FAQ
What is the maximum output current capability of the VDD regulator in MCZ33905CD5EKR2?
The MCZ33905CD5EKR2 provides a 5.0 V VDD output rated for 300 mA when used with an optional external PNP ballast transistor. Without the external transistor, the internal LDO delivers up to 150 mA. This scalability allows designers to match MCU current demand while minimizing BOM cost and board area.
Does MCZ33905CD5EKR2 support both LIN 2.1 and SAE J2602-2 standards?
Yes, MCZ33905CD5EKR2 fully supports both LIN 2.1 and SAE J2602-2 standards across its dual LIN interfaces. Each LIN channel operates at data rates from 10.4 kB/s to 20 kB/s (with 100 kB/s fast mode), and includes built-in diagnostics, short-circuit protection, and bus failure detection per specification.
How many wake-up sources can be configured on MCZ33905CD5EKR2?
MCZ33905CD5EKR2 supports up to four configurable wake-up sources. These I/O pins (I/O-0 to I/O-3) can be dynamically assigned in hardware or firmware as either wake-up inputs or LIN master termination outputs-enabling flexible ECU wake strategies without changing PCB layout.
What is the purpose of the SAFE pin on MCZ33905CD5EKR2?
The SAFE pin on MCZ33905CD5EKR2 is an open-drain output directly linked to the internal fail-safe state machine. It asserts during fault conditions (e.g., overtemperature, undervoltage, or watchdog timeout) to signal downstream circuits-allowing controlled shutdown of critical loads like motors or heaters to meet ASIL-B functional safety goals.
Is MCZ33905CD5EKR2 compatible with the KIT33905D5EKEVBE evaluation board?
Yes, MCZ33905CD5EKR2 is fully supported by the KIT33905D5EKEVBE evaluation board. This board demonstrates all key features including dual-LIN operation, CAN communication, configurable wake-up I/Os, and fail-safe state transitions-enabling rapid validation of MCZ33905CD5EKR2 in target applications before full-system integration.
