MCZ33903CS5EKR2

The MCZ33903CS5EKR2 from NXP Semiconductors is a second-generation System Basis Chip (SBC) that enhances module designs by integrating advanced power management for MCUs and other ICs like sensors and CAN transceivers. It features a built-in high-speed CAN interface compliant with ISO11898-2 and -5, offering diagnostics, protection, and fail-safe operation. The device may also include one or two LIN 2.1/J2602-2 interfaces.

This SBC supports multiple low-power modes with very low current consumption, typically 15 µA with VDD off. It operates within a voltage range of 5.5V to 28V, with a maximum input voltage of 27 VDC (40V Load Dump). The device includes an MCU voltage regulator (VDD) and a ballast regulator (VAUX), with an output current of up to 300 mA. It supports CAN data rates from 40 kB/s to 1.0 MB/s and LIN data rates from 10.4 kB/s to 20 kB/s.

The MC33903/4/5 family offers pin compatibility for design versatility. It implements an advanced fail-safe state machine and is supported by an ecosystem including evaluation boards and conformance reports, easing time to market. The device is housed in a 32-SSOP exposed pad package and is surface-mount compatible.

Key applications include body control modules, gateways, seat modules, lighting control, HVAC, clusters, seat belt pre-tensioners, electric parking brakes, steering systems, fuel pumps, water pumps, and engine management systems. The device also features robust physical layers certified to stringent EMC, ISO, and ESD standards.
