Apollo4 - 面向电池驱动的智能Endpoint IoT设备实时在线语音应用的低功耗SoC

功耗低至3uA/MHz，Ambiq Micro最新的低功耗SoC产品家族Apollo系列，最新产品Apollo 4，为下一代端点(Endpoint)智能设备带来创纪录的能效(Record-setting Energy Efficiency)和全新的性能标杆(New Level of Performance)。

News Highlights:

• The Apollo4 SoC family is implemented onTSMC® 22nm ULL process and based on a32-bit Arm® Cortex®-M4 processor with FPU and Arm Artisan® physical IP
• Achieving an unmatched 3 μA/MHz from MRAM with low deep sleep current modes
• Up to 192 MHz clock frequency using TurboSPOT™
• 2D/2.5D graphics accelerator and MIPI DSI 1.2 with up to two lanes at 500Mbps per lane delivering a feature-rich user interface
• Apollo4 Blue integrates a Bluetooth Low Energy 5 radio including 2Mbps support as well as direction-finding Angle of Arrival (AOA) and Angle of Departure (AOD) for always-on applications
• Proprietary audio interfaces and ultra-low power analog microphone for truly always-on voice processing
• 8 PDM channels, 2 stereo I2S channels with ASRC, and an ultra-low power ADC for analog microphones

Ambiq Micro，作为低功耗MCU, SoC， RTC(Real Time Clock)的技术领导者，于2020年9月14日正式发布其Apollo 4 SoC产品族。

Apollo0 4是Ambiq Micro基于其特有的SPOT(Subthreshold Power-Optimized Technology)技术平台的第四代产品，将赋能下一代的电池驱动的端点智能设备，在不牺牲电池待机时间的情况下，达到更高水平的智能水平。(higher level of intelligence without sacrificing battery life)。

Apollo4目前支持CSP和BGA另种封装，同时Apollo 4 Blue支持蓝牙LE。

Apollo4专为(purpose-built)既需要一定的应用处理芯片能力，又需要一定的协处理能力的电池驱动的端点智能设备而设计，包括智能手表，儿童手表，健康手环，动物追踪器，远场语音控制，可预测性健康和维护设备，智能安全设备和其他智能家庭设备等。

随着越来越多的智能IOT设备需要24/7实时服务，在ARM和TSMC最新技术的支持下，Apollo 4 SoC是低功耗和高系统能力的完美融合。

Aollo 4 SoC支持2MB的MRAM和1.8MB的SRAM，Apollo 4 SoC具备足够的计算和存储能力以支持复杂的算法和神经网络处理能力(handle complex algorithms and neural networks while displaying vibrant, crystal-clear, and smooth graphics)，同时支持动态，清晰和平滑的显示支持。若需要额外的外部存储能力，同时支持Multi-bit SPI和e.MMC。

随之以十亿的电池驱动的智能设备正在进入我们的生活，对高能效计算提出了更高的要求(power-efficient processing)。Arm Cortex-M4处理器内核和Arm Artisan physical IP，可以进一步支持Ambiq的always-on用户体验，包括实时语音处理和丰富的图像显示能力。

在前期采用TSMC 40nm工艺的基础上，TSMC的22ULL技术，结合Ambiq的技术专长，我们带来极具竞争力的低漏电集成电路技术。TSMC 创新的22nm技术内嵌MRAM，对于Apollo 4的MCU片上代码存储极其关键。

About Ambiq

Ambiq was founded in 2010 with the mission to foster a cleaner, greener, and safer environment where mobile and portable devices could either reduce or eliminate their total power consumption from the batteries. For the last ten years, we laser-focused on nothing but inventing and delivering the most revolutionary RTC and MCU solutions for the market. Through the advanced Subthreshold Power Optimized Technology (SPOT™) platform, Ambiq has helped many leading manufacturers around the world create products that can operate for days, months, and sometimes years with a single charge.

In 2020, we achieved our most significant milestone – over 75 million devices are embedded with an Ambiq chip. On the heels of this success and the experience and know-how we’ve accumulated, we set out for another ambitious goal in the next decade. We aim to bring intelligence to all battery-powered endpoint devices and enable them to stay connected intuitively, and unobtrusively, to create a real IoT era. We hope to partner with you on our next journey.
