技术问答

兆易创新2004年成立于美国硅谷，目前公司总部设在北京，专注于各类存储器和控制器的设计、研发和销售。GD是国内第一家存储器产品行业的上市企业，Flash累计出货量超过100亿颗。

Nor Flash的Block Protect(块保护)功能可以通过软件设置保护特定区域不被擦除(Erase)或写入数据(Page Program)。本文主要以兆易创新的GD25Q80C为例，介绍Nor Flash的Block Protect(块保护)功能。

在GD25Q80C中，与Block Protect(块保护)相关的设置为寄存器内的BP4、BP3、BP2、BP1、BP0和CMP位。如下图

寄存器使用Write Status Register指令(指令码01H)进行配置。只有当BP2、BP1、BP0、CMP都为0或者都为1时才可以执行Chip Erase(全片擦除)命令。CMP位主要用于和BP4-BP0配合连用，从而可以更灵活的配置对哪些块设置保护。关于BP4-BP0和CMP的配置表如下图，第一张图为CMP=0时的配置信息，第二张图为CMP=1时的配置信息。

【应用】高集成压力传感器搭配高精度电流传感器、温湿度传感器实现医用双水平呼吸机，降低设计难度及成本

传统医用双水平呼吸机设计中，压力传感器要外加放大、校准电路，设计复杂，增加了PCB布板面积和BOM成本，由于缺少在吸气管路内进一步控温和对环境温湿度的监测，造成吸气管路内温度变化大，会出现水珠滴到病人面部体验感差等问题。为解决上述问题，本方案采用高集成的压力传感器搭配了高精度的电流传感器、高精度温湿度传感器等器件，实现了高性价比医用双水平呼吸机的设计。本方案的系统框图：
