NXP Semiconductors MCZ33903DP3EK

MCZ33903DP3EK is the 3.3 V MC33903P variant in NXP's second-generation system basis chip family. It combines the functions commonly needed around an automotive microcontroller: battery-supplied power management, an enhanced high-speed CAN physical interface, wake-up inputs, reset and interrupt signaling, and a serial configuration interface. NXP's orderable-part table identifies the P version as a no-LIN configuration with three wake-up inputs; do not assume features of the S or D LIN variants are present.

The catalog package is 32-SSOP Exposed Pad. NXP identifies the exact part with package version SOT1762-2 (SSOP32). The package drawing describes a 32-terminal, 0.65 mm-pitch body approximately 11 mm by 7.5 mm by 2.3 mm. Use the controlled drawing and recommended land pattern for board layout; the exposed ground lead frame needs the specified thermal and electrical connection.

Layout checks

• Match SOT1762-2 terminal numbering and exposed-pad geometry.
• Check pad soldering and ground-return recommendations in the NXP package drawing.
• Keep CAN bus routing, protection, and termination consistent with the system schematic.

Package image pending: the registered JPG is absent locally and the production image URL currently returns HTTP 404. This draft must not be published until the actual image is available and verified.

The following groups summarize functions shown for the MC33903P in the NXP pin-connection and pin-definition sections. Use the NXP pin-number table, not this summary, when assigning schematic nets.

The exact pin numbers, no-connect treatment, and operating-mode functions must be verified from the MC33903P drawing and Table 4 of the current datasheet.

Electrical thresholds, regulator load limits, CAN timing, and typical currents vary by operating mode and test conditions; consult the applicable NXP electrical-characteristics tables before component selection.

NXP lists other MC33903 orderable variants, but they are not unconditional replacements. A 5.0 V VDD variant changes the MCU supply, while S and D variants add LIN functions and can change pin usage and system behavior. Compare the complete suffix, package version, exposed-pad footprint, power rails, CAN behavior, SPI configuration, temperature range, and required safety behavior before any substitution. No internal catalog replacement link is asserted here because an exact candidate catalog match and compatibility assessment have not been completed.

NXP Semiconductors documents MCZ33903DP3EK in its MC33903/MC33904/MC33905 family documentation and exact-part product-content declaration. Refer to the current controlled datasheet, package drawing, and any applicable product-change notices when qualifying this order code.

Confirm the complete NXP order code, top marking, package version, and traceability documents during incoming inspection. A catalog listing alone does not establish automotive qualification, application fitness, or authorized-channel provenance. Check the current manufacturer documentation and project-specific quality requirements before approval.

Use this page as a selection summary, not as a substitute for the latest NXP datasheet, package drawing, or application validation. Confirm the full order code, actual silicon revision, electrical limits, thermal path, EMC behavior, and CAN system design. The missing production package image prevents publication of this draft.
