Description The TSE2004GB2B0 digital temperature sensor with accuracy up to ±0.5°C was designed to target applications demanding highest level of temperature readout. The device also contains 512 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. The digital temperature sensor comes with several user-programmable 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. The sensor uses an industry standard 2-wire, I2C/SMBus serial interface, and allows up to eight devices to be controlled on the bus. The 4Kbit (512 Bytes) serial EEPROM memory in the part is organized as two pages of 256 bytes each, or 512 bytes of total memory. Each page is comprised of two 128 byte blocks. The devices are able to selectively lock the data in any or all of the four 128-byte blocks.
