The thermal management for the Intel Core series of processors consists of a sensor located in
the core processor area. The processor contains multiple techniques to help better manage
thermal attributes of the processor. It implements thermal-based clock throttling and thermal-
based speed step transitions. There is one thermal sensor on the processor that triggers Intel's
thermal monitor (the temperature at which the thermal sensor triggers the thermal monitor is set
during the fabrication of the processor). Triggering of this sensor is visible to software by means
of the thermal interrupt LVT entry in the local APIC.

System RAM

The Blackbird has DDR4 memory with the following characteristics:

I/O Interfaces

Later chapters describe the Blackbird's I/O interfaces and their associated connectors as follows:
Mass Storage Interfaces (SATA) beginning on page 31

Multi-purpose I/O (USB, Mini PCIe / mSATA, User I/O), beginning on page 33

Serial I/O, beginning on page 44

Video Interfaces (Mini DisplayPort++ and LVDS), beginning on page 47

Network Interfaces, beginning on page 53

Real-Time Clock (RTC)

The Blackbird features a real-time clock/calendar (RTC) circuit. The Blackbird supplies RTC
voltage in S5, S3, and S0 states, but requires an external +2.75 V to +3.3 V battery connection.
Refer to the section titled Battery Power Options on page 25 for more information. The BIOS
Setup utility sets the RTC.
