Features 02

Computational Horsepower

Arm Cortex-M4F core offers the computational horsepower required in an internet of things (IoT) world.

Power Efficiency

As low as 4 μA/MHz power efficiency to meet the most battery constrained processing needs.

Reduced Sleep Current

Integrates a power switch with ~1 Ω impedance to cut-off ground current on the host SoC and reduce sleep current to < 1 nA.

Optimized Power Modes

Optimize both active and sleep mode power.

Power-Optimized Sensor

Intelligent peripheral management for power-optimized sensor processing.

Multiple Package Options

Offered in BGA and WLCSP package options.

Sensor Application Processor

Serves as an application processor for one or more sensors (some have a fully integrated Bluetooth Low Energy 5 radio).

Internet of Things

The Apollo processors, integrated with analog, digital, radio frequency circuitry, multiple interfaces, and other functionalities onto one tiny package, allow manufacturers the capability of running sensing, data storage, analysis, inference, security, and communications all within an ultra-low power budget. Close to 100 millions hearables, wearables, medical monitors, IoT devices, and wireless remote sensors are benefiting from the Apollo family by gaining the flexibility to dramatically increase battery life, adding more complex intelligent processing, all the while using less or smaller batteries, or unique power supplies, to provide the ultimate customer experiences.
