SE98

DDR memory module temp sensor, 3.3 V

Rev. 04 — 2 February 2009

Product data sheet

1. General description

The NXP Semiconductors SE98 measures temperature from

−40 °C

to +125

°C

communicating via the I

C-bus/SMBus. It is typically mounted on a Dual In-line Memory

Module (DIMM) measuring the DRAM temperature in accordance with the new JEDEC

(JC-42.4)

Mobile Platform Memory Module Thermal Sensor Component

speciﬁcation.

Placing the Temp Sensor (TS) on DIMM allows accurate monitoring of the DIMM module

temperature to better estimate the DRAM case temperature (T

case

) to prevent it from

exceeding the maximum operating temperature of 85

°C.

The chip set throttles the

memory trafﬁc based on the actual temperatures instead of the calculated worst-case

temperature or the ambient temperature using a temp sensor mounted on the

motherboard. There is up to a 30 % improvement in thin and light notebooks that are

using one or two 1G SO-DIMM modules, although other memory modules such as in

server applications will also see an increase in system performance. Future uses of the

TS will include more dynamic control over thermal throttling, the ability to use the Alarm

Window to create multiple temperature zones for dynamic throttling and to save processor

time by scaling the memory refresh rate.

The TS consists of an Analog-to-Digital Converter (ADC) that monitors and updates its

own temperature readings 8 times per second, converts the reading to a digital data, and

latches them into the data temperature registers. User-programmable registers, such as

Shutdown or Low-power modes and the speciﬁcation of temperature event and critical

output boundaries, provide ﬂexibility for DIMM temperature-sensing applications.

When the temperature changes beyond the speciﬁed boundary limits, the SE98 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 microprocessor-based systems. The EVENT output

can even be conﬁgured as a critical temperature output.

The SE98 supports the industry-standard 2-wire I

C-bus/SMBus serial interface. The

SMBus TIMEOUT function is supported to prevent system lock-ups. Manufacturer and

Device ID registers provide the ability to conﬁrm the identify of the device. Three address

pins allow up to eight devices to be controlled on a single bus. To maintain

interchangeability with the I

C-bus/SMBus interface the electrical speciﬁcations are

speciﬁed with the operating voltage of 3.0 V to 3.6 V.
