MCZ33904C3EK

Specialized Overview

The MCZ33904C3EK is a System Basis Chip (SBC) from the second-generation MC33903/4/5 family, designed as an advanced power management unit for microcontrollers and integrated circuits. It features a built-in enhanced high-speed CAN interface compliant with ISO11898-2 and -5 standards, providing local and bus failure diagnostics along with fail-safe operation modes. The device includes a flexible MCU voltage regulator (VDD) available in 3.3 V or 5.0 V configurations, delivering up to 150 mA internally, which can be extended to 300 mA using an optional external ballast transistor. It also incorporates an auxiliary LDO regulator (VAUX), multiple low-power modes with ultra-low current consumption, and quad configurable I/O pins with wake-up capabilities.

Specialized Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type, temperature range, and lead-free status. Ensure compatibility with existing PCB footprints and design requirements before procurement. Cross-reference part numbers with authorized distributors to avoid counterfeit components.

Specialized Selection Notes

Select this component when a single-chip solution combining MCU power regulation and high-speed CAN communication is required. Consider the internal 150 mA output limit; if higher current is needed, plan for an external ballast transistor. Verify that the 3.3 V VDD output meets the target microcontroller's voltage requirements.
