AmbiQ Micro 智能穿戴设备超低功耗方案商

AmbiQ Micro 是一家专注于研发超低功耗芯片产品的美资企业,其产品特点如下:

1、采用先进的SPOT技术(亚阈值功率优化技术)

SPOT技术上世纪由物理学家发现,2004年开始由美国密西根大学研究,经过六年发展,2010年正式应用到产品里面,在美国奥斯汀成立了Ambiq Micro这家以研发生产低功耗IC为主的公司。

SPOT技术重新定义了超低功率半导体的含义,为芯片建立了新的标准,从而使得功耗做得更低。

2、Ambiq Micro具有最低功耗的MCU产品

 功耗:  程序运行于Flash功耗 :35μA/MHz

       程序运行于RAM功耗  : 34μA/MHz

       睡眠模式(RTC打开)功耗:143nA

采用Cortex-M4内核,含浮点运算,具备Sensor Hub管理能力,内置一个+/-2°C的温度传感器。
包括具有50个GPIO的64脚4.5 x 4.5mmBGA封装,以及尺寸进一步优化的具有27个GPIO的41脚2.49 x 2.90mmCSP封装。

应用场合:可穿戴设备、便携设备、Sensor Hub、健康医疗、仪器仪表等低功耗小体积的场合。

 

3、Ambiq Micro具有世界最低功耗的RTC产品

功耗:高精度晶振模式下的功耗–55nA(精度+/-2ppm)

    自动校准+RC振荡器模式功耗–22nA(精度+/-16ppm)

    仅RC振荡器模式的功耗–14nA

  另外AM18XX系列还集成了电源管理、复位、256bytes RAM、外部中断等功能。提供一个欧姆的接地开关,支持换电复位,

  使用该系列RTC,将会简化您的电路,使用体积更小价格更便宜的纽扣电池(SR512的纽扣电池即可使用30年),省下复位芯片和EEPROM的成本。

应用场合:可穿戴设备、便携设备、追踪器、RFID、仪器仪表等需要低功耗小体积的场合(在低占空比场合其优势更加明显)

Description
The Apollo MCU family is an ultra-low power, highly integrated microcontroller designed for batterypowered devices including wearable electronics,activity & fitness monitors, and wireless sensors. By combining ultra-low power sensor conversion electronics with the powerful ARM Cortex-M4F processor, the Apollo MCU enables complex sensor processing tasks to be completed with unprecedented battery life. Weeks, months, and years of battery life are achievable while doing complex context detection, gesture recognition, and activity monitoring. The Apollo MCU takes full advantage of Ambiq Micro’s patented Subthreshold Power Optimized Technology (SPOT) Platform, setting a new industry benchmark in low power design. The Apollo MCU also integrates up to 512 KB of flash memory and 64 KB of RAM to accommodate radio and sensor overhead while still leaving plenty of space for application code. This microcontroller also includes a serial master and UART port for communicating with radios and sensors including accelerometers, gyroscopes, and magnetometers.
