描述 Description

Microchip Technology Inc.’s MCP98244 digital

temperature sensor converts temperature from -40°C

and +125°C to a digital word. This sensor meets

JEDEC Specification JC42.4-TSE3000B1 Memory

Module Thermal Sensor Component. It provides an

accuracy of ±0.2°C/±1°C (typical/maximum) from

+75°C to +95°C with an operating voltage of 1.7V to

3.6V. In addition, MCP98244 has an integrated

EEPROM with two banks of 256 by 8 bit EEPROM (4k

Bit) which can be used to store memory module details

and vendor information.

The MCP98244 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 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). It has four 128 Byte pages,

which can be Software Write Protected individually.

This allows DRAM vendor and product information to

be stored and write-protected.

This sensor has an industry standard I2C Fast Mode

Plus compatible 1 MHz serial interface.
