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 6 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 MCU 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 BLE5 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.

Highlighted Products 03

Apollo3 Blue Plus

With an integrated Arm Cortex-M4 processor with Floating Point Unit (FPU) and Ambiq TurboSPOT, Apollo3 Blue Plus propels the computational capabilities to 96 MHz while lowering the active power consumption to < 6 µA/MHz.

Ultra Thin with Backside Coating

As thin as 300 µm and perfect for contactless biometric cards, including payment, authentication, access, and more.

Multiple Serial Protocol Support

Multiple I²C, SPI, or I²S protocols over the serial slave port for host processor communication.

ADC with Analog and Digital Outputs

Capable of measuring both analog and digital sensor outputs via its integrated ultra-low power 14-bit ADC.
