Overview
The Texas Instruments AM4378BZDN80 is a high-performance processor from the Sitara AM437x family, based on the ARM Cortex-A9 core. This processor is designed to provide robust processing capabilities, enhanced with 3D graphics acceleration and a Programmable Real-Time Unit Subsystem and Industrial Communication Subsystem (PRU-ICSS) for deterministic, real-time processing. It supports high-level operating systems such as Linux, which is available free of charge from TI, and other operating systems from TI's Design Network and ecosystem partners. The AM4378BZDN80 is ideal for upgrading systems based on lower-performance ARM cores, offering advanced peripherals and memory options like QSPI-NOR and LPDDR2.
