• 256 Byte EEPROM for SPD3.3VDD_SPDSDASCLEventInc.’s MCP98242 digitalMicrochip Technologytemperature sensor converts temperature from -40°Cand +125°C to a digital word. This sensor meetsJEDEC Specification JC42.4 Mobile Platform MemoryModule Thermal Sensor Component. It provides anaccuracy of ±0.5°C/±1°C (typical/maximum)from+75°C to +95°C. In addition, this device has an internal256 Byte EEPROM which can be used to store memorymodule and vendor information.theThe MCP98242 digital temperature sensor comes withuser-programmable registers that provide flexibility forDIMM temperature-sensing applications. The registersallow user-selectable settings such as Shutdown orspecification ofLow-Power modes andtemperature event and critical output boundaries.When the temperature changes beyond the specifiedboundary limits, the MCP98242 outputs an Eventsignal. The user has the option of setting the Eventoutput signal polarity as either an active-low oractive-high comparator output for thermostat operation,or as aformicroprocessor-based systems. The Event output canalso be configured as a critical temperature output.temperature eventinterrupt outputThe EEPROM is designed specifically for DRAMDIMMs (Dual In-line Memory Modules) Serial PresenceDetect (SPD). The lower 128 bytes (address 00h to7Fh) can be Permanent Write-Protected (PWP) orSoftware Reversible Write-Protected (SWP). Thisallows DRAM vendor and product information to bestored and write-protected. The upper 128 bytes(address 80h to FFh) can be used for general purposedata storage. These addresses are not write-protected.This sensor has an industry standard 2-wire, I2C/SMBus compatible serial interface, allowing up to eightdevices to be controlled in a single serial bus. ToI2C/SMBusmaintaininterface the electrical specifications are specified withthe operating voltage of 3.0V to 3.6V. In addition, a40 ms (typical) time out is implemented.
