Description	1C Remote Diode Temperature Sensor
Datasheet	LM64_NationalSemiconductor.pdf

The LM64 is a remote diode temperature sensor with PWM fan control.

a PWM, open-drain, fan control output, 5 GPIO (General Purpose Input/Output) and 5 GPD (General Purpose Default) pins. The 8-step Lookup Table allows for a non-linear fan speed vs. temperature transfer function often used to quiet acoustic fan noise.
