SoC delivers dual-mode Bluetooth for edge devices
Ambiq’s Apollo510D Lite SoC provides both Bluetooth Classic and BLE 5.4 connectivity, enabling always-on intelligence at the edge. It is powered by a 32-bit Arm Cortex-M55 processor running at up to 250 MHz with Helium vector processing and Ambiq’s turboSPOT dynamic scaling. A dedicated Cortex-M4F network coprocessor operating at up to 96 MHz handles wireless and sensor-fusion tasks.
According to Ambiq, its Subthreshold Power Optimized Technology (SPOT) delivers 16× faster performance and up to 30× better AI energy efficiency than comparable M4- or M33-based devices. The SoC’s BLE 5.4 radio subsystem provides +14 dBm transmit power, while dual-mode capability supports low-power audio streaming and backward compatibility with Classic Bluetooth.
The Apollo510D Lite integrates 2 MB of RAM and 2 MB of nonvolatile memory with dedicated instruction/data caches for faster execution. It also includes secureSPOT 3.0 and Arm TrustZone to enable secure boot, firmware updates, and data protection across connected devices.
Along with the Apollo510D Lite (dual-mode Bluetooth), Ambiq’s lineup includes the Apollo510 Lite (no BLE radio) and the Apollo510B Lite (BLE-only). The Apollo510 Lite series is sampling now, with volume production expected in Q1 2026.
