MCZ33903DP3EKR2

Specialized Overview

The MCZ33903DP3EKR2 is a System Basis Chip (SBC) from NXP Semiconductors, part of the second-generation 33903/4/5 family. It integrates an advanced power management unit for microcontrollers with an enhanced high-speed CAN interface compliant with ISO11898-2 and -5 standards. The device features a selectable VDD output voltage of either 5.0 V or 3.3 V, specifically 3.3 V in this variant. It includes up to four programmable wake-up input pins that can also function as general-purpose I/Os. The component operates within a supply voltage range of 5.5 V to 28 V and supports a maximum baud rate of 1.0 Mb/s on the CAN bus. It utilizes SMARTMOS technology and is housed in a 32-pin SOIC package.
