If your assembly line or end-market requires RoHS compliance, you need a different order code (e.g., the LM86CIMM/NOPB variant) or a lead-free alternative. ## Local + remote sensing with programmable limits The LM86CIMM is a digital temperature sensor that measures both its own die temperature (local) and the temperature of an external diode-connected transistor (remote), giving you two temperature points from one IC. Local resolution is 8 bits; the remote channel resolves to 11 bits, which is enough to catch small thermal drifts in a CPU or FPGA die via a substrate PNP. Communication is over a 2-wire I²C/SMBus interface, so it shares the bus with other sensors, EEPROMs, or GPIO expanders without extra pins. Built-in features include a one-shot conversion mode for on-demand reads, a programmable limit register that can assert an ALERT output, and both shutdown and standby modes to cut power between readings in a low-power system. ## Supply rail, accuracy, and temperature window The rated accuracy is ±3°C over the full operating range (0°C to 125°C), which is adequate for thermal monitoring and fan-control loops but not for precision calibration work. Local and remote sensing ranges are each specified from 0°C to 85°C, while the device itself can survive ambient up to 125°C — the remote channel can track a hot CPU die even when the board ambient is well above 85°C. ## Package and board-fit details Surface-mount only; the 0.65 mm pitch is fine for a two-layer board but a ground plane under the device helps with thermal coupling for the local reading.","metaTitle":"Texas Instruments LM86CIMM Digital Temp Sensor, 8/11b","metaDescription":"Active Texas Instruments LM86CIMM digital local/remote temp sensor, 8b local/11b remote resolution, I2C/SMBus, 3-3.6V, 0-125°C.
