Product details
Overview
MCZ33905CD5EK from NXP (formerly Freescale) is a second-generation System Basis Chip (SBC) integrating high-speed CAN, dual LIN 2.1/J2602-2 transceivers, 5.0 V MCU LDO (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. It operates from 5.5–28 V input, supports -40 °C to 125 °C ambient, and delivers 15 µA quiescent current in VDD-OFF low-power mode.
For engineers reviewing the MCZ33905CD5EK datasheet, MCZ33905CD5EK pinout, MCZ33905CD5EK application, or MCZ33905CD5EK equivalent, key selection considerations include dual-LIN wake-up flexibility (up to 4 configurable I/Os), ISO 11898-2/5 and LIN 2.1 compliance, cranking pulse resilience, secured SPI with watchdog, and analog monitoring via integrated MUX.
Technical Context
The MCZ33905CD5EK implements a hardware-configurable fail-safe state machine linked to the SAFE pin, with cranking-aware under-voltage management and programmable reset timing. Its dual LIN interfaces support independent 10.4–20 kB/s data rates (100 kB/s fast mode), while the enhanced CAN physical layer complies with ISO 11898-2 and -5, including bus failure diagnostics and local/remote wake-up detection.
Power architecture includes three regulated outputs: VDD (5.0 V, up to 300 mA with external PNP), VAUX (5.0 V configurable), and dedicated 5.0 V VCAN supply. Analog sensing is consolidated through a multiplexer with high-precision VSUP monitoring and VSENSE inputs, enabling real-time battery and system voltage tracking without MCU intervention.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDD Output Voltage | 5.0 V ±2%, supports 300 mA with optional external ballast transistor - enables scalable MCU power delivery across platform variants. |
| CAN Interface | High-speed, ISO 11898-2 and -5 compliant - provides robust, fault-tolerant vehicle network connectivity with bus failure diagnostics. |
| LIN Interfaces | Dual LIN 2.1 / SAE J2602-2 compliant - allows independent control of two LIN subnets (e.g., door + seat modules) with configurable termination. |
| Low-Power Current | 15 µA (VDD OFF), 25 µA (VDD ON) - minimizes battery drain during ECU sleep states while maintaining CAN/LIN wake-up capability. |
