Austin, TX – September 14, 2020 Ambiq, a technology leader recognized in ultra-low power microcontrollers (MCU), System-on-Chips (SoC), and Real-time Clocks (RTC), is introducing the new Ambiq Apollo4 SoC family. The Apollo4 SoC family is the fourth generation system processor solution built upon Ambiq’s proprietary Subthreshold Power-Optimized Technology (SPOT) platform. The Apollo4’s complete hardware and software solution enables the battery-powered endpoint devices of tomorrow to achieve a higher level of intelligence without sacrificing battery life. The Apollo4 enables manufacturers to create leading-edge endpoint devices leveraging the unique SPOT platform with Ambiq’s easy-to-use, rich peripheral set. The Apollo4 is available now with CSP and BGA offerings, as well as an Apollo4 Blue with Bluetooth® LE.   
The Apollo4 is purpose-built to serve as both an application processor and a coprocessor for batterypowered endpoint devices, including smartwatches, children’s watches, fitness bands, animal trackers, far-field voice remotes, predictive health and maintenance devices, smart security devices, and smart home devices.  

 “As the market is shifting towards adding billions of smart devices* at endpoints in the coming years, the need for energy efficiency is beyond critical to sustaining the realization of an IoT world where everything stays connected 24/7,” said Dan Cermak, VP of Architecture and Product Planning at Ambiq. “Building on the advanced technologies from Arm and TSMC, our Apollo4 SoC family presents the perfect combination of increased system capability with significantly reduced power consumption for all battery-powered endpoint devices.”   
With up to 2MB of MRAM and 1.8MB of SRAM, the Apollo4 has enough compute and storage to handle complex algorithms and neural networks while displaying vibrant, crystal-clear, and smooth graphics.  If additional memory is required, external memory is supported through Ambiq’s multi-bit SPI and e.MMC interfaces.   “A world of trillion intelligent devices, many of which are battery-powered, emphasizes the need for power-efficient processing,” said Kiran Burli, senior director of marketing and licensing, Physical Design Group, Arm. “The use of the Arm Cortex-M4 processor and Arm Artisan physical IP enables Ambiq to deliver an always-on user experience, including rich graphics and voice processing, for endpoint devices where ultra-low power consumption is critical.”  
“TSMC is delighted to have another successful collaboration with Ambiq building on what we achieved together starting from the 40nm generation to make smart IoT devices even smarter with extended battery life,” said Simon Wang, Senior Director of IoT Business Development at TSMC. “Our 22ULL technology complements Ambiq’s design expertise with the most competitive ultra-low power planar technology to enable low leakage with enhanced computing power to support value-added IoT features.  TSMC's innovative 22nm embedded MRAM technology, which was adopted in Apollo4, is essential to support on-chip code storage for MCU functions to achieve industry-leading power performance.”
