MCZ33291EG

Overview

The MCZ33291EG is a System Basis Chip (SBC) designed for automotive applications, integrating a microcontroller unit with power management and communication interfaces. It features an ARM Cortex-M0+ core operating at up to 48 MHz, combined with a 5V regulator, LIN transceiver, and CAN transceiver. The device supports ISO 26262 functional safety requirements and includes comprehensive diagnostic features such as voltage monitoring, temperature sensing, and watchdog timers. Packaged in a TSSOP-28 form factor, it provides a compact solution for body control modules and gateway applications requiring robust connectivity and power distribution.

Feature Summary

• Integrates ARM Cortex-M0+ microcontroller with LIN and CAN communication interfaces
• Provides integrated 5V power regulation and multiple output channels
• Supports functional safety compliance through built-in diagnostics and error detection
• Features low-power modes and flexible pin configuration for system optimization

Applications

• Automotive Body Control Modules (BCM)
• Gateway nodes in vehicle networks
• Lighting control units
• Seat and window control systems
• Door control electronics

Procurement Notes

Verify the specific suffix 'EG' corresponds to the required tape-and-reel packaging and temperature grade. Confirm that the lead-free status and RoHS compliance meet current regulatory requirements for your region. Ensure the ordering part number matches the exact package type and marking code needed for your assembly process. Cross-reference the datasheet revision date to ensure compatibility with your design specifications.

Selection Notes

Select this component when a single-chip solution combining processing, power management, and dual bus connectivity is required. It is suitable for designs needing ISO 26262 ASIL B compliance without external MCU. Consider the thermal performance of the TSSOP-28 package for your enclosure constraints. Evaluate if the integrated LIN and CAN transceivers reduce bill-of-materials compared to discrete solutions.

Part Context

This SBC belongs to NXP's Z33 series, which targets cost-sensitive automotive applications. It complements higher-performance SBCs by offering a balance of integration and price. The series is designed to simplify PCB layout by reducing component count. It fits within the broader ecosystem of NXP automotive microcontrollers and power devices.

Replacement Considerations

Direct replacements may include other NXP SBCs with similar pinouts and functionality, such as the MCZ33290 or MCZ33292, depending on specific feature requirements like additional outputs or different safety levels. Verify electrical compatibility and software migration efforts before substituting.
