MAX78000
Artificial Intelligence Microcontroller with Ultra-
Low-Power Convolutional Neural Network
Accelerator
General Description
Artificial intelligence (AI) requires extreme computational
horsepower, but Maxim is cutting the power cord from
AI insights. The MAX78000 is a new breed of AI mi-
crocontroller 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. Our
hardware-based convolutional neural network (CNN) ac-
celerator enables battery-powered applications to execute
AI inferences while spending only microjoules of energy.
The MAX78000 is an advanced system-on-chip featuring
an Arm® Cortex®-M4 with FPU CPU for efficient system
control with an ultra-low-power deep neural network accel-
erator. The CNN engine has a weight storage memory of
442KB, and can support 1-, 2-, 4-, and 8-bit weights (sup-
porting 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 512KB
of data memory. The CNN architecture is highly flexible,
allowing networks to be trained in conventional toolsets
like PyTorch® and TensorFlow®, then converted for exe-
cution 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 mi-
crocontroller core, with 512KB flash and up to 128KB
SRAM. Multiple high-speed and low-power communica-
tions interfaces are supported, including I2S and a parallel
camera interface (PCIF).
The device is available in a 81-pin CTBGA (8mm x 8mm,
0.8mm pitch) package.
