The package footprint is 0.76 x 0.76 mm, a 4-ball BGA with a 0.4 mm pitch. This height constraint is the spec that drives the board-stacking decision. If your assembly has a 0.2 mm gap between the PCB and an adjacent display, battery, or cover glass, this sensor fits without a mechanical shim or cutout. The 0.15 mm profile includes the solder balls after reflow — the bare package is even thinner. That means no derating or calibration offset needed when the sensor moves from a room-temperature test bench to a hot enclosure or cold start. The 16-bit resolution gives a temperature step of roughly 0.0078°C per LSB. For a thermal management loop that needs to detect a 0.5°C drift before the system throttles, the noise floor of the ADC is the limiting factor — not the resolution. The datasheet's typical noise performance at 1.8V supply is the number to check for your control bandwidth. ## 1.2V-capable supply — runs off the core rail Supply range is 1.08V to 1.98V, which means this sensor runs directly from a 1.2V core rail without a separate LDO or voltage divider. The 1.2V-capable feature in the description confirms the sensor operates at the low end of the range, not just at 1.8V. Current consumption in active conversion is in the microamp range; the One-Shot mode lets the sensor sleep between readings and draw near-zero standby current. For a battery-powered IoT node taking a temperature reading once per minute, the average draw is dominated by the I²C bus activity, not the sensor itself. ## 4-PICOSTAR rework reality The 4-PICOSTAR package is a 0.76 x 0.76 mm BGA with four balls on a 0.4 mm pitch. The solder balls are under the package — there are no exposed side pads. Rework requires a hot-air station with a nozzle small enough to target the 0.76 mm body without heating adjacent components. Texas Instruments lists no direct successor or pin-compatible alternative for this order code. The TMP114 family shares the same package and interface across accuracy grades; the NCIY variant is the ±1°C grade in the 4-PICOSTAR package.","metaTitle":"TMP114NCIYMTR Texas Instruments Digital Temp Sensor, ±1°C","metaDescription":"Texas Instruments TMP114NCIYMTR digital temperature sensor, 16-bit resolution, ±1°C accuracy, 1.08-1.98V supply, 4-PICOSTAR package.
