Product details
Overview
MCZ33905CS5EK from NXP (formerly Freescale) is a second-generation System Basis Chip (SBC) integrating high-speed CAN, single LIN 2.1/J2602-2 transceiver, 5.0 V MCU regulator (150 mA standard, up to 300 mA with external PNP), internal 5.0 V CAN regulator, and fail-safe state machine - designed as power management and communication hub for automotive body control modules, seat modules, and lighting controllers.
For engineers reviewing the MCZ33905CS5EK datasheet, MCZ33905CS5EK pinout, MCZ33905CS5EK application, or MCZ33905CS5EK equivalent, key selection criteria include its 5.0 V VDD output, ISO 11898-2/5-compliant CAN interface, single LIN transceiver, 15 µA sleep current, and SOIC-32 exposed-pad package - all validated for -40 °C to +125 °C operation in 5.5–28 V automotive systems.
Technical Context
The MCZ33905CS5EK implements a secured SPI interface with watchdog capability, configurable wake-up I/Os (up to 4 pins usable as wake-up inputs or LIN termination outputs), and high-precision VSUP sensing with analog MUX for battery voltage, temperature, and signal monitoring. Its fail-safe state machine is hardware-linked to the SAFE pin and supports cranking pulse management during low-VDD conditions.
It integrates dual-regulator architecture: a primary 5.0 V LDO for MCU supply (VDD) and a dedicated 5.0 V regulator for CAN transceiver (VCAN), plus VAUX configurable as 3.3 V or 5.0 V auxiliary supply. All regulators support under-voltage detection and thermal shutdown per ISO 16750-2.

Equivalent & Alternatives
The following parts are listed as comparable options for similar System Basis Chip applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCZ33905BS5EK/R2 | 3.3 V VDD output; same SOIC-32 package, identical pinout and feature set except regulator voltage | Required where host MCU operates at 3.3 V logic level and cannot accept 5.0 V supply | Select when MCU VDD specification mandates 3.3 V - no layout change needed due to pin compatibility |
| MCZ33904C5EK/R2 | No LIN interface; retains CAN, 5.0 V VDD, 150 mA output, and 4 wake-up I/Os in same SOIC-32 package | Suitable for CAN-only gateways or modules without LIN-connected peripherals | Choose when LIN functionality is unnecessary - lower cost and reduced software stack complexity |
Compared with MCZ33905CS5EK, MCZ33905BS5EK/R2 offers identical integration and packaging but delivers 3.3 V instead of 5.0 V to the MCU, while MCZ33904C5EK/R2 removes LIN entirely - enabling cost-optimized CAN-centric designs without sacrificing thermal performance or fail-safe architecture.

FAQ
What is the maximum output current capability of the VDD regulator in MCZ33905CS5EK?
The MCZ33905CS5EK provides a nominal 150 mA continuous output from its 5.0 V VDD regulator. With an optional external PNP ballast transistor, it supports up to 300 mA - verified in the official MC33903_4_5FS datasheet Rev. 6.0. This scalability allows the same MCZ33905CS5EK footprint to serve both low-power and higher-current MCU platforms without redesign.
Does MCZ33905CS5EK support both LIN 2.1 and SAE J2602-2 standards?
Yes, MCZ33905CS5EK fully complies with both LIN 2.1 and SAE J2602-2 physical layer specifications. Its integrated LIN transceiver (pins RXD-L, TXD-L, LIN-T) meets timing, voltage threshold, and fault-tolerance requirements defined in both standards - confirmed in Freescale's MC33903_4_5FS documentation and conformance test reports.
What is the purpose of the SAFE pin on MCZ33905CS5EK?
The SAFE pin on MCZ33905CS5EK is an open-drain output directly tied to the hardware fail-safe state machine. It asserts low during detected faults (e.g., overtemperature, undervoltage, CAN bus-off) to trigger external safety actions - such as disabling power stages or alerting the MCU - independent of software execution. This behavior is documented in the MC33903_4_5FS datasheet Section 8.3.10.
Can MCZ33905CS5EK operate during automotive cranking events?
Yes, MCZ33905CS5EK implements innovative cranking pulse management that maintains critical functions - including CAN monitoring, SAFE assertion, and wake-up detection - even when VSUP drops below 6 V. Its internal regulation and state machine ensure deterministic behavior without external hold-up capacitors, as validated per ISO 16750-2 Pulse 4a testing.
Is MCZ33905CS5EK pin-compatible with other members of the MC33905 family?
Yes, MCZ33905CS5EK shares identical pinout and package (SOIC-32 exposed pad) with MCZ33905BS5EK/R2, MCZ33905CS3EK/R2, and MCZ33905BS3EK/R2. All variants maintain full electrical and mechanical compatibility - only VDD voltage (3.3 V vs. 5.0 V) and LIN count (single vs. dual) differ, enabling flexible platform design without PCB revision.
