This New Product Brief (NPB) is part of a video series highlighting the features, applications, and technical specs of newly-released products.

MAXIM INTEGRATED MAX78000 Ultra-Low-Power Arm Cortex-M4 Processor

Maxim Integrated MAX78000 integrates an ultra-low-power MCU with a hardware-based convolutional neural network accelerator, enabling AI inference in battery-powered applications. 

The MAX78000 features a dual-core 100MHz Arm Cortex-M4 processor with FPU for system control and a 60MHz RISC-V coprocessor for signal processing. It also has an ultra-low-power CNN accelerator with 442KB weight storage memory, with the weights stored in SRAM allowing for on-the-fly updates to the AI network. The device has multiple interfaces, including a parallel camera interface and I2S audio interface to capture images and audio for processing by the CNN. 

For ease of use, developers can train networks on popular AI toolsets then convert them for execution on the MAX78000 using Maxim’s tools. The IC also offers comprehensive power management to maximize battery life.
