Local sensing uses 7-bit resolution; the remote channel resolves to 10 bits, giving finer granularity for the external device — typically the thermal diode on a CPU, FPGA, or ASIC die. ## Temperature accuracy and operating envelope The local sensing range is 0°C to 85°C, matching the remote channel's range; the IC itself is specified to operate up to 125°C ambient, so the die can be placed in a warmer zone while the remote diode sits in the 0°C to 85°C target region. Test conditions cover 25°C to 125°C, confirming the accuracy holds across the upper half of the operating band where thermal management decisions matter most. ## Built-in operational modes The sensor includes one-shot conversion, an output switch, programmable temperature limits, shutdown mode, and standby mode — the one-shot command lets the system take a single reading without continuous conversion, saving bus traffic and supply current. The programmable limit and output switch allow the LM89CIMX/NOPB to assert an interrupt or alert pin when the temperature crosses a threshold, offloading the host from polling the SMBus.","metaTitle":"LM89CIMX/NOPB Texas Instruments Temp Sensor, ±3°C, SMBus","metaDescription":"Texas Instruments LM89CIMX/NOPB digital local/remote temperature sensor, ±3°C accuracy, SMBus output, 8-SOIC package.
