3µA/MHz Ambiq Apollo 4 MCU Targets Battery-powered IoT Devices with Voice Processing

Ambiq Micro is using sub-threshold voltages under 0.5V to offer ultra-low-power Arm microcontrollers. In 2015, the company launch the Apollo Cortex-M4F MCU with 30µA/MHz power consumption in active mode, which was followed in 2016 by Apollo 2 in consuming just 10µA/MHz, and Apollo 3 (Blue)  dropped power consumption to as low as 6µA/MHz against using a Cortex-M4F @ 48 MHz in active mode. The fourth generation of ultra-low-power Apollo microcontroller has now been announced with Apollo 4 and Apollo 4 Blue microcontrollers – the latter adding Bluetooth – halving the power consumption of Apollo 3 at just 3µA/MHz, or ten times less than the original ultra-low-power MCU from the company. Apollo 4 (Blue) specifications and key features: MCU Core – Arm Cortex-M4F core up to 192 MHz (TurboSPOT) with FPU, Memory Protection Unit (MPU), and Secure Boot GPU – 2D/2.5D graphics accelerator with full alpha blending, texture and frame buffer compression Ultra-Low Power Memory Up to 2MB of non-volatile MRAM …
