Product details
Overview
The MCZ33905BD5EKR2 from NXP (formerly Freescale) is a second-generation System Basis Chip (SBC) integrating high-speed CAN, dual LIN transceivers, 5.0 V MCU regulator (300 mA with external ballast), internal 5.0 V CAN regulator, and fail-safe state machine - designed as a power management and communication hub for automotive body control modules requiring ISO 11898-2/5 and LIN 2.1/J2602-2 compliance.
For engineers reviewing the MCZ33905BD5EKR2 datasheet, MCZ33905BD5EKR2 pinout, MCZ33905BD5EKR2 application, or MCZ33905BD5EKR2 equivalent, key selection considerations include its dual-LIN capability, 5.0 V VDD output, SOIC-54EP package, 15 µA sleep current, and configurable wake-up/I/O pin mapping for ECU-level flexibility in safety-critical automotive systems.
Technical Context
This SBC implements an enhanced high-speed CAN physical layer compliant with ISO 11898-2 and -5, supporting data rates from 40 kB/s to 1 MB/s, with bus failure diagnostics and fail-safe operation. It integrates two independent LIN 2.1/J2602-2 transceivers operating at 10.4–20 kB/s (100 kB/s fast mode), each with configurable LIN termination outputs.
The device features a secured SPI interface with watchdog capability, a configurable fail-safe state machine linked to the SAFE pin, and ultra-low-power modes (15 µA with VDD off). Its analog monitoring includes VSUP sense, VSENSE, and MUX-based analog inputs for battery voltage, temperature, and signal conditioning in harsh automotive environments.

What is the VDD output voltage and maximum current capability of the MCZ33905BD5EKR2?
The MCZ33905BD5EKR2 provides a fixed 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 scalable architecture allows designers to optimize for cost or performance based on MCU power requirements in the target ECU.
Does the MCZ33905BD5EKR2 support both CAN and LIN communication simultaneously?
Yes, the MCZ33905BD5EKR2 integrates one high-speed CAN interface compliant with ISO 11898-2 and -5, and two independent LIN 2.1/J2602-2 transceivers - enabling concurrent CAN gateway and dual-LIN subnetwork communication in a single chip. Both interfaces operate with dedicated regulators and diagnostics.
What package type and pin count does the MCZ33905BD5EKR2 use?
The MCZ33905BD5EKR2 uses a 54-pin SOIC Wide-body package with exposed thermal pad (SOICW-EP, suffix EK), matching the pinout of other dual-LIN Gen2 SBCs like MCZ33905CD5EKR2. This package supports automotive thermal dissipation requirements and mechanical robustness in under-hood environments.
How does the MCZ33905BD5EKR2 handle low-voltage conditions during engine cranking?
The MCZ33905BD5EKR2 implements innovative cranking pulse management that maintains regulated 5.0 V VDD output even when input voltage drops below 6 V during engine start. This eliminates the need for large hold-up capacitors and preserves MCU operation and LIN/CAN wake-up capability without external circuitry.
Is the MCZ33905BD5EKR2 qualified for automotive applications and what safety features does it include?
Yes, the MCZ33905BD5EKR2 is AEC-Q100 qualified for automotive use and includes hardware-based safety features: a configurable fail-safe state machine linked to the SAFE pin, secured SPI with watchdog, VSUP and VSENSE monitoring, and diagnostics for CAN/LIN bus failures - supporting ASIL-B system-level functional safety goals.
