MICROCHIP MCP98244T-BE/MNY Temperature Sensor IC, Digital, ± 1°C, -40 °C, 125 °C, TDFN, 8 Pins

The MCP98244T-BE/MNY is a Digital Temperature Sensor that converts temperature from -40 and +125°C to a digital word. The device 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 boundaries. When the temperature changes beyond the specified event boundary limits, the MCP98244 outputs an alert signal at the event pin. The user has the option of setting the temperature 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 MCP98244 EEPROM is designed specifically for DRAM DIMMs (Dual In-line Memory Modules) Serial Presence Detect (SPD).

• 4kB Serial EEPROM for serial presence detect (SPD)
• 100µA (typical, EEPROM Idle) Operating Current
• 1MHz, 2-wire I²Câ�¢ Interface
• Serial EEPROM operating current - Read 100µA (typical)
• Reversible software write protect
• Software write protection for each 1Kbit Block
• Organized as two banks of 256 x 8-bit (2kB x 2)
• Meets JEDEC Specification - JC42.4-TSE2004B1
