Wireless SoC raises AI efficiency at the edge

The Apollo510B wireless SoC from Ambiq combines a 48-MHz dedicated network coprocessor with a Bluetooth LE 5.4 radio for power-efficient edge AI. Its Arm Cortex-M55 CPU, enhanced with Helium vector processing and Ambiq’s turboSPOT dynamic scaling, delivers up to 30× greater AI efficiency and 16× faster performance than Cortex-M4 devices. 

With 64 KB each of instruction and data cache, 3.75 MB of RAM, and 4 MB of embedded nonvolatile memory, the Apollo510B provides fast, real-time processing. Its 2D/2.5D GPU handles vector graphics, while SPI, I²C, UART, and high-speed USB 2.0 support flexible sensor and device connections. High-fidelity audio is enabled via a low-power ADC and stereo digital microphone PDM interfaces.

Apollo510B also integrates secureSPOT 3.0 and Arm TrustZone, enabling secure boot, firmware updates, and protection of data exchange across connected devices. These features make the device well-suited for always-on, intelligent applications such as wearables, smart glasses, remote patient monitoring, asset tracking, and industrial automation.

The Apollo510B SoC will be available in fall 2025.
