Block Diagram for the Apollo Ultra-Low Power SoC

Open

More Information

Weeks, months, and years of battery life are achievable while doing complex context detection, gesture recognition, and activity monitoring. The Apollo SoC takes full advantage of Ambiq’s patented Sub-threshold Power Optimized Technology (SPOT^®) Platform, setting a new industry benchmark in low power design.

The Apollo SoC also integrates up to 512KB of flash memory and 64KB of RAM to accommodate radio and sensor overhead while still leaving plenty of space for application code. This system on a chip also includes a serial master and UART port for communicating with radios and sensors including accelerometers, gyroscopes, and magnetometers.

Feature Highlights

An ideal solution for battery-powered applications requiring sensor measurement and data analysis.

Can measure analog sensor outputs using an integrated ultra-low power 10-bit ADC and digital sensor outputs using the integrated serial master ports.

Capable of running complex data analysis and sensor fusion algorithms to process the sensor data.

Enables months and years of battery life for products only achieving days or months of battery life today.

Implementation of the Cortex-M4F core delivers both greater performance and much lower power than 8-bit, 16-bit, and other comparable 32-bit cores.

ADC is uniquely tuned for minimum power with a configurable measurement mode that does not require SoC intervention.

Supported by a complete suite of standard software development tools.
