Its ±1°C typical accuracy (±3°C over the full range) suits board-level thermal monitoring. The sensor covers -20°C to 125°C, which spans the industrial and automotive cabin range. Below -20°C the accuracy is not specified — if your cold-start requirement dips below that, this part won't give you a reliable reading. ## Shutdown and standby — saving power between reads The part includes a shutdown mode and a standby mode, letting the system power down the sensor between temperature conversions. For a battery-powered IoT node that reads temperature once a minute, these modes cut the average current draw significantly — the I²C bus can be idle and the sensor sleeping until the host wakes it for a measurement. An output switch and programmable limit register are also on board. The limit can be set to trigger an alert when the temperature crosses a threshold, offloading the host from polling the I²C bus continuously. ## 8-UDFN (2x3) — small footprint, exposed pad rework The 8-UDFN package with exposed pad (2 mm x 3 mm body) is a common footprint for small sensors. The exposed pad needs a thermal via or a solid copper pour under it to conduct heat from the board into the sensor — without it, the self-heating error adds to the reading. Under a hot-air station, the small thermal mass means the part reaches reflow temperature quickly; just watch the pad alignment — the package is symmetric and the pin-1 mark is a small dot that can be hard to see under flux residue. The I²C bus voltage must match the supply or use a level shifter if the host runs at a different logic level. ROHS3 compliance is confirmed. No AEC-Q qualification is listed, so if the target is an automotive under-hood application, verify the qualification separately — the -20°C to 125°C range alone does not guarantee automotive-grade reliability testing.","metaTitle":"AT30TSE004A-MA5M-T Digital Temp Sensor, I²C, ±1°C, 8-UDFN","metaDescription":"Microchip AT30TSE004A-MA5M-T digital local temperature sensor, I²C output, ±1°C typical accuracy, -20°C to 125°C range, 8-UDFN package.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Package":"Tape & Reel (TR); Cut Tape (CT)","Features":"Output Switch, Programmable Limit, Shutdown Mode, Standby Mode","Resolution":"10 b","Output Type":"I²C","Sensor Type":"Digital, Local","Mounting Type":"Surface Mount","Package / Case":"8-UFDFN Exposed Pad","Test Condition":"75°C ~ 95°C (-20°C ~ 125°C)","lifecycle_stage":"eol_hot","Voltage - Supply":"1.7V ~ 3.6V","Operating Temperature":"-20°C ~ 125°C","Supplier Device Package":"8-UDFN (2x3)","Accuracy - Highest (Lowest)":"±1°C (±3°C)","Sensing Temperature - Local":"-20°C ~ 125°C"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.25","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$1.25000","currency":"USD"},{"qty":25,"price":"$1.20000","currency":"USD"},{"qty":5000,"price":"$1.20000","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/32054b382a29f588b5cfbad9f7941c71.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the accuracy of AT30TSE004A-MA5M-T?","answer":"Typical accuracy is ±1°C; the worst-case over the full -20°C to 125°C range is ±3°C.
