MCZ33905CS3EK

Specialized ICS Overview

The MCZ33905CS3EK is a System Basis Chip (SBC) manufactured by Freescale Semiconductor, designed for automotive applications. It integrates power management and communication interfaces, featuring two 3.3 V low-dropout regulators with a combined output current capability of 400 mA. The device supports LIN bus communication and includes multiple wake-up inputs for system control. It operates within an input voltage range of 5.5 V to 28 V and is qualified for the automotive grade. The component is housed in a 32-SOIC-EP package with an exposed pad for thermal dissipation, suitable for surface-mount installation.

Specialized ICS Feature Summary

• Integrates two 3.3 V/400 mA LDOs for efficient power distribution
• Supports LIN bus communication protocol for module-to-module data exchange
• Includes multiple wake-up inputs for flexible system activation
• Automotive-grade qualification ensuring reliability in vehicle environments

Specialized ICS Applications

• Automotive body electronics systems
• LIN-based sensor and actuator networks
• Microcontroller power supply units in vehicles

Specialized ICS Procurement Notes

Verify the manufacturer designation as Freescale Semiconductor or NXP Semiconductors, as the brand transition occurred during product lifecycle. Confirm the specific suffix CS3EK corresponds to the 32-SOIC-EP package and automotive grade. Check RoHS compliance status and ensure the ordering quantity matches the bulk packaging format specified in the source data.

Specialized ICS Selection Notes

Select this component when a dual 3.3 V regulator solution with integrated LIN interface is required for automotive microcontrollers. Ensure the design accommodates the 32-SOIC-EP package footprint and thermal requirements due to the exposed pad. Verify that the 5.5 V to 28 V input voltage range aligns with the vehicle's power supply specifications.

Specialized ICS Part Context

This part belongs to the MCZ33905 series of System Basis Chips, which combine power management and communication functions. It is often used in conjunction with automotive microcontrollers to simplify board design. The series typically offers variants with different regulator voltages and communication interfaces such as CAN or LIN.

Specialized ICS Replacement Considerations

Check for direct pin-compatible alternatives within the MCZ33905 family, such as variants with different LDO outputs or additional interfaces like CAN. Verify that any substitute maintains the same 32-SOIC-EP package and automotive qualification level.
