MAX78000 neural network accelerator chip

22 November 2023 AI & ML

The MAX78000 is a new breed of AI microcontroller built to enable neural networks to execute at ultra-low power and live at the edge of the IoT. This product combines the most energy-efficient AI processing with Maxim’s proven ultra-low power microcontrollers. The hardware-based convolutional neural network (CNN) accelerator enables even battery-powered applications to execute AI inferences.

The advanced system-on-chip design features an Arm Cortex-M4 with FPU CPU for efficient system control with an ultra-low-power deep neural network accelerator. The CNN engine has a weight storage memory of 442 kB, and can support 1-, 2-, 4-, and 8-bit weights (supporting networks of up to 3,5 million weights). The CNN weight memory is SRAM-based, so AI network updates can be made on the fly. The CNN engine also has 512 kB of data memory and its architecture is highly flexible, allowing networks to be trained in conventional toolsets like PyTorch and TensorFlow, then converted for execution on the MAX78000 using tools provided by Maxim.

In addition to the memory in the CNN engine, the MAX78000 has large on-chip system memory for the microcontroller core, with 512 kB flash and up to 128 kB SRAM. Multiple high-speed and low-power communications interfaces are supported, including I2S and a parallel camera interface.

The device is available in an 81-pin CTBGA (8 x 8 x 0.8 mm pitch) package.

Typical applications for the MAX78000 include audio processing (multi-keyword recognition, sound classification, noise cancellation), facial recognition, object detection and classification, and time-series data processing such as heart rate signal analysis, multi-sensor analysis, and predictive maintenance.
