MCP98242

www.DataSheet4U.com MCP98242 Memory Module Temperature Sensor w/EEPROM for SPD Features Temperature Sensor + 256 Byte Serial EEPROM EEPROM for Serial Presence Detect (SPD) Optimized for Voltage Range: 3.0V to 3.6V Shutdown/Standby Current: 3 µA (maximum) 2-wire Interface: I2C™/SMBus™-Compatible Available Packages: DFN-8, TDFN-8, TSSOP-8 Description Microchip Technology Inc.’s MCP98242 digital temperature sensor converts temperature from -40°C and +125°C to a digital word. This sensor meets JEDEC Specification JC42.4 Mobile Platform Memory Module Thermal Sensor Component. It provides an accuracy of ±0.5°C/±1°C (typical/maximum) from +75°C to +95°C. In addition, this device has an internal 256 Byte EEPROM which can be used to store memory module and vendor information. The MCP98242 digital temperature sensor comes with user-programmable registers that provide flexibility for DIMM temperature-sensing applications. The registers allow user-selectable settings such as Shutdown or Low-Power modes and the specification of temperature event and critical output boundaries. When the temperature changes beyond the specified boundary limits, the MCP98242 outputs an Event signal. The user has the option of setting the Event output signal polarity as either an active-low or active-high comparator output for thermostat operation, or as a temperature event interrupt output for microprocessor-based systems. The Event output can also be configured as a critical temperature output...
