Terminology 
 
Term Definition 
A “#” symbol after a signal name refers to an active low signal, indicating 
a signal is in the active state when driven to a low level. For example, 
when RESET# is low, a reset has been requested. Conversely, when NMI 
is high, a non-maskable interrupt has occurred. In the case of signals 
where the name does not imply an active state but describes part of a 
binary sequence (such as address or data), the “#” symbol implies that 
the signal is inverted. For example, D [3:0] = “HLHL” refers to a hex ‘A’, 
and D [3:0]# = “LHLH” also refers to a hex “A” (H= High logic level, L= 
Low logic level).  
Front Side Bus 
(FSB) 
Refers to the interface between the processor and system core logic (also 
known as the GMCH chipset components). 
AGTL+ 
Advanced Gunning Transceiver Logic. Used to refer to Assisted GTL+ 
signaling technology on some Intel processors. 
CMOS Complementary 
metal-Oxide semiconductor. 
Storage 
Conditions 
Refers to a non-operational state. The processor may be installed in a 
platform, in a tray, or loose. Processors may be sealed in packaging or 
exposed to free air. Under these conditions, processor landings should not 
be connected to any supply voltages, have any I/Os biased, or receive any 
clocks. Upon exposure to “free air” (i.e., unsealed packaging or a device 
removed from packaging material) the processor must be handled in 
accordance with moisture sensitivity labeling (MSL) as indicated on the 
packaging material. 
Enhanced Intel 
SpeedStep® 
Technology 
Technology that provides power management capabilities to low power 
devices. 
Processor Core 
Processor core die with integrated L1 and L2 cache. All AC timing and 
signal integrity specifications are at the pads of the processor core.
