Device Overview
AT30TS74-XM8M-T is an I2C/SMBus-compatible digital temperature sensor in an 8-lead 3 mm x 3 mm MSOP package. It operates from 1.7 V to 5.5 V and supports I2C High-Speed mode up to 3.4 MHz.
Resolution is selectable from 9 to 12 bits, corresponding to 0.5 °C down to 0.0625 °C per LSB. The exact XM8M-T ordering row is specified for -55 to 125 °C operation.

Engineering Selection Guidance
Resolution and accuracy are different specifications. Selecting 12-bit conversion gives 0.0625 °C per LSB, but it does not make absolute temperature accuracy 0.0625 °C.
Accuracy must also retain its temperature condition: the documented typical error is ±1.0 °C from -20 to +100 °C and ±2.0 °C from -40 to +125 °C. Neither figure should be extended automatically to the full -55 to +125 °C operating range.
The 3.4 MHz value refers to I2C High-Speed mode and assumes a compatible controller and bus. The exact XM8M code selects the 8-lead 3 mm x 3 mm MSOP package, while the T suffix is the packing option.
