Microchip Technology TC1066
The TC1066 is a serially programmable temperature sensor optimized for monitoring modern high performance CPUs with on-board integrated thermal diodes. This permits reading the current internal/external temperature, programming the threshold setpoints, and configuring the device. Communication with the TC1066 is accomplished via the standard System Management Bus (SMBus) commonly used in modern computer systems.| Part No. | TC1066 |

Temperature data is converted from the CPU’s thermal diode outputs and made available as an 8-bit digital word. Additionally, an interrupt is generated on the ALERT#/COMP# pin when temperature moves outside the preset threshold windows in either direction. A separate CRITICAL setpoint is provided through external hardwiring for “fail safe” operation per ACPI guidelines.
