MCP98242

Memory Module Temperature Sensor w/ EEPROM for SPD

Features

Description

• 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 (max.)

• 2-wire Interface: I²C™/SMBus™-Compatible

• Available Packages: TSSOP-8, DFN-8

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 (typ./max.) 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.

Temperature Sensor Features

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 micropro-

cessor-based systems. The Event output can also be

configured as a critical temperature output.

• Temperature-to-Digital Converter

• Operating Current: 200 µA (typ.)

• Accuracy:

^{- ±0.5°C/±1°C (typ./max.)}→ +75°C to +95°C

^{- ±1°C/±2°C (typ./max.)}→ +40°C to +125°C

^{- ±2°C/±3°C (typ./max.)}→ -20°C to +125°C

Serial EEPROM Features

• Operating Current:

- Write → 1.1 mA (typ.) for 3.5 ms (typ.)

- Read → 100 µA (typ.)

• Permanent and Reversible Software Write Protect

• Software Write Protection for the lower 128 bytes

• Organized as 1 block of 256 bytes (256x8)

The EEPROM is designed specifically for DRAM

DIMMs (Dual In-line Memory Modules) Serial Presence

Detect (SPD). The lower 128 bytes (address 00h to

7Fh) can be Permanent Write Protected (PWP) or Soft-

ware Reversible Write Protected (SWP). This allows

DRAM vendor and product information to be stored and

write protected. The upper 128 bytes (address 80h to

FFh) can be used for general purpose data storage.

These addresses are not write protected.

Typical Applications

• DIMM Modules

• Laptops, Personal Computers and Servers

• Hard Disk Drives and Other PC Peripherals

This sensor has an industry standard 2-wire,

I²C/SMBus compatible serial interface, allowing up to

eight devices to be controlled in a single serial bus. To

maintain interchangeability with the I²C/SMBus

interface the electrical specifications are specified with

the operating voltage of 3.0V to 3.6V. In addition, a

40 ms (typ.) time out is implemented.
