MCP98208中文资料Temperature Sensors数据手册Microchip规格书

描述 Description

The MCP98208 digital temperature sensor convertstemperatures between -20°C and +60°C to a digital word with ±0.5°C (max.)accuracy. The MCP98208 includes the ultimate value-added features andfunctionality making it a perfect fit for Cold Chain/Supply Chain Data-logger applications toinclude Pharmaceutical Data-logger applications and others. TheMCP98208 implements customer-specified temperature accuracy verification eliminatingthe high cost need to use third party test houses (or Customer in-house resources) to verify a temperaturesensor’s temperature accuracy. The MCP98208 uses an ISO/IEC-17025 accredited productionflow. In addition, the MCP98208 has an internal 256-byte EEPROM that can be usedto store user-customizable data or specific product information, critically importantto enhancing the application's system performance and reliability. The EEPROM providesultimate data storage and protection capabilities with Permanent Write-Protect and Software Reversible Write-Protect options. This device has user-selectable settings such asshutdown or low-power modes and the specification of temperature Event andCritical output boundaries. TheMCP98208 has an industry standard 2-wire, I2C™Compatible compatible serialinterface, allowing up to eight sensors to be controlled in a single serialbus. The MCP98208 device is available in a space saving2 x 3 mm, 8-lead TDFN package.
