7.6Test Access Port (TAP) Connection

Due to the voltage levels supported by other components in the Test Access Port (TAP) logic, Intel recommends the processor be first in the TAP chain, followed by any other components within the system. A translation buffer should be used to connect to the rest of the chain unless one of the other components is capable of accepting an input of the appropriate voltage. Two copies of each signal may be required with each driving a different voltage level.

The processor supports Boundary Scan (JTAG) IEEE 1149.1-2001 and IEEE 1149.6-2003 standards. A few of the I/O pins may support only one of those standards.

7.7DC Specifications

The processor DC specifications in this section are defined at the processor pins, unless noted otherwise. See Signal Description on page 82 for the processor pin listings and signal definitions.

•The DC specifications for the DDR3/DDR3L signals are listed in the Voltage and Current Specifications section.

•The Voltage and Current Specifications section lists the DC specifications for the processor and are valid only while meeting specifications for junction temperature, clock frequency, and input voltages. Read all notes associated with each parameter.
