概述

生物识别传感器集中器应用算法支持更快上市时间
基于手指(版本A)的算法测量
- 脉搏心率
- 脉搏血氧饱和度(SpO2)
提供原始和计算得到的数据
基本外设混合优化尺寸和性能
- 1个从机I²C接口，用于与主机控制器通信
- 1个主机I²C接口，用于与传感器通信
- 32.768kHz RTC
- FIFO提供最低程度的主机处理器介入
- 安全、经过认证的固件升级

MAX32664为传感器集中器家族，带有适合可穿戴设备的嵌入式固件和算法。器件无缝支持客户所需的传感器功能，包括与Maxim的光学传感器方案通信，以及为外部提供原始或计算得到的数据。在实现以上功能的同时，保证系统总功耗在控制范围之内。

MAX32664版本A支持MAX30101/MAX30102高灵敏度脉搏血氧仪和心率传感器，适用于基于手指的可穿戴健康应用。

MAX32664版本B支持MAX86140/MAX86141，适用于基于腕戴的监测。

传感器集中器接口提供可连接到微控制器主机的快速模式、I²C从机接口。第二个I²C接口专用于与传感器通信。

微小尺寸(1.6mm x 1.6mm、16焊球WLP封装)，允许集成到极小体积的应用设备。
