Product Details
MCZ33905DD5EK - Dual-LIN System Basis Chip
NXP Semiconductors MCZ33905DD5EK combines 5 V microcontroller power management, high-speed CAN and two LIN interfaces in a 54-terminal exposed-pad SOIC/HSOP package.
The exact ordering row and package outline are documented by NXP. The catalog's SSOP label still needs reconciliation with NXP SOT1747-3 before a package image can be accepted.
Overview
The MC33905D is an automotive system basis chip integrating regulated supplies, a high-speed CAN transceiver, two LIN physical interfaces, wake-up logic, supervision and SPI-controlled configuration. The DD5EK ordering entry selects the D version with a 5.0 V VDD regulator and the 54-pin exposed-pad package.
Key Advantages
Combines high-speed CAN and dual LIN channels with power management.
The DD5 order code provides a 5.0 V VDD regulator option.
Configurable pins support combinations of wake-up inputs and LIN master terminations.
Manufacturer documentation describes voltage, current, temperature and network fault monitoring.
Feature Summary
Integrated protected transceiver with dedicated CANH and CANL connections.
LIN-1 and LIN-2 provide separate local network interfaces in the D variant.
VAUX-related functions provide a configurable auxiliary supply path for system components.
Serial registers configure operating modes and report status to the host MCU.
Package & Footprint
NXP lists MCZ33905DD5EK in SOT1747-3 / HSOP54, a 54-terminal exposed-pad SOIC outline with 0.65 mm lead pitch and approximately 7.5 mm by 17.9 mm body. The original catalog field is 54-SSOP (0.295 inch, 7.50 mm width) Exposed Pad, while its local registry label is 54-SSOP Exposed Pad. The SOIC/HSOP versus SSOP designation requires manual mechanical reconciliation; do not infer footprint identity from the similar width alone.
- Use NXP drawing 98ASA10506D / SOT1747-3 for dimensions.
- Confirm the 54-terminal 0.65 mm lead arrangement.
- Verify exposed-pad size, ground contact and thermal path.
The registered JPG is absent locally and on the production site. No package artwork has been validated for this product.
Pin Functions

Use the complete datasheet for regulator load limits, CAN/LIN electrical characteristics and thermal derating; the ordering table alone is not a design-limit specification.
Replacement Considerations
Match the 5 V regulator variant, dual-LIN channel count, CAN physical layer, SPI map, wake-up/termination choices, exposed-pad thermal path and exact SOT1747-3 footprint. A 32-pin MC33905S or 3.3 V option is not an unconditional substitute. No internal catalog alternative is linked without an exact API match and electrical review.
Manufacturer Information
The API names NXP Semiconductors. NXP's MC33903/MC33904/MC33905 datasheet explicitly lists MCZ33905DD5EK/R2 with 5.0 V VDD, two LIN interfaces and the 54-pin exposed-pad SOT1747-3 package. NXP's package page independently lists the unsuffixed MCZ33905DD5EK in the same HSOP54 family.
Applications
MCU supply supervision and in-vehicle network connectivity.
Combination of one high-speed CAN bus and two LIN subnets.
Wake-up and low-power mode management for distributed modules.
Identification and qualification of existing MC33905D system basis chip positions.
Quality & Authenticity
Check the exact top marking, 54-pin outline, exposed pad, lead condition and lot traceability. Electrical acceptance should cover regulator startup, SPI identification, CAN/LIN communication and protection behavior under appropriate system conditions.
FAQ
What distinguishes DD5EK?
NXP's ordering table identifies the D version with two LIN channels, a 5.0 V VDD option and a 54-pin exposed-pad package.
Is the package an ordinary SSOP?
No equivalence should be assumed. NXP calls it SOT1747-3 HSOP54/SOIC; the catalog SSOP name needs mechanical review.
Can a single-LIN version replace it?
Not without redesign. The single-LIN option uses a different pin count and omits one LIN channel.
Is the package JPG available?
No. The expected production JPG returns 404 and has not been validated.
Engineering Notice
Verify the exact NXP ordering variant, SOIC/HSOP versus catalog SSOP designation, SOT1747-3 drawing, exposed-pad grounding, supply loads, CAN/LIN wiring and SPI configuration before use. The package mapping and production JPG are unresolved, so this draft remains under review and must not be published.
