MCP98243  
Memory Module Temperature Sensor w/ EEPROM for SPD  
Features  
Description  
• Meets JEDEC Specification JC42.4-TSE2002B3  
• Temperature Sensor + 2 Kbit Serial EEPROM  
• EEPROM for Serial Presence Detect (SPD)  
• 2-wire I2C™/SMBus Interface  
Microchip Technology Inc.’s MCP98243 digital  
temperature sensor converts temperature from -40°C  
and +125°C to a digital word. This sensor meets  
JEDEC Specification JC42.4-TSE2002B3 Platform  
Memory Module Thermal Sensor Component. It  
provides an accuracy of ±0.2°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.  
• Available Packages:  
- DFN-8, TDFN-8, UDFN-8, TSSOP-8  
Temperature Sensor Features  
• Temperature-to-Digital Converter  
The MCP98243 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 boundaries. When the temperature  
changes beyond the specified Event boundary limits,  
the MCP98243 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.  
• Sensor Accuracy (Grade B):  
- ±0.2°C/±1°C (typ./max.) → +75°C to +95°C  
- ±0.5°C/±2°C (typ./max.) → +40°C to +125°C  
- ±1°C/±3°C (typ./max.) → -20°C to +125°C  
• Specified VDD Range: 3.0V to 3.6V  
• Operating Current: 200 µA (typical)  
• Operating VDD Range: 2.7V to 5.5V  
Serial EEPROM Features  
• Specified VDD Range: 1.8V to 5.5V  
• Operating Current:  
The EEPROM is designed specifically for DRAM  
DIMMs (Dual In-line Memory Modules) Serial Presence  
Detect (SPD). The lower 128 Bytes (address 0x00 to  
0x7F) can be Permanent Write Protected (PWP) or  
Software Reversible Write Protected (SWP). This  
allows DRAM vendor and product information to be  
stored and write protected. The upper 128 bytes  
(address 0x80 to 0xFF) can be used for general  
purpose data storage. These addresses are not write  
protected.  
- Write → 1.1 mA (typical) for 3.5 ms (typical)  
- Read → 100 µA (typical)  
• Permanent and Reversible Software Write Protect  
• Software Write Protection for the lower 1 Kbit  
• Organized as 1 block of 256 x 8-bit (2 Kbit)  
Typical Applications  
• DIMM Modules for Servers, PCs, and Laptops  
• General Purpose Temperature Datalog  
This sensor has an industry standard 2-wire,  
I2C compatible serial interface, allowing up to eight  
devices to be controlled in a single serial bus.
