Device Overview

±0.5°C was designed to target applications demanding highest level of

temperature readout. The device also contains 256 Byte EEPROM for

storage of vendor information and system configuration such as SPD for

DIMM modules. The sensor and the EEPROM are fully compliant with

JEDEC JC42.4 Component Specification.

mable registers to provide maximum flexibility for temperature-sensing

applications. The registers allow specifying critical, upper, and lower

temperature limits as well as hysteresis settings. Both the limits and

hysteresis values are used for communicating temperature events from

the chip to the system. This communication is done using Event pin,

which has an open-drain configuration. The user has the option of

setting the Event pin 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.

face, and allows up to eight devices to be controlled on the bus.

nized as a single block. Half the bytes in memory locations 00h to 7Fh

can be permanently locked with user defined or vendor defined informa-

tion. The protected data could also contain system information such as

access speed, size, and organization. The 128 bytes in addresses from

80h to FFh can be used for general purpose data storage. These

addresses are not write-protected.
