2.1.5 
Signal Differences Between the Mobile Intel Celeron Processor 
(0.18 µ) (in BGA2 and Micro-PGA2 Packages) and the Mobile 
Intel Celeron Processor (0.13 µ) (in Micro-FCBGA and Micro-
FCPGA Packages) 
A list of new and changed signals is shown in Table 1. 
Table 1. New and Revised Mobile Intel Celeron Processor (0.13 µ) Signals 
Signals Function 
BCLK, BCLK#  Differential host clk signals. 
 CLKREF 
Host Clock reference signal in Single Ended Clocking mode. 
BSEL[1:0] 
Signals are output only instead of I/O.  Please refer to the Appendix for details. 
DPSLP# 
Deep Sleep pin (replaces SLP# pin on the mobile Celeron processor (0.18 µ)) 
NCTRL 
AGTL output buffer pull down impedance control. 
VID[4:0] 
Voltage Identification (different implementation from mobile Celeron processor (0.18 µ)).  Please refer 
to Section 3.2.3 for details. 
VTTPWRGD 
Power Good signal for VCCT, which indicates that, the VID signals are stable.  Please refer to Figure 
3 for VTTPWRGD system level connections.

2.2.1 
Clock Control Architecture  
The Mobile Intel Celeron Processor clock control architecture (Figure 1) has been optimized for leading 
edge mobile computer designs. The clock control architecture consists of six different clock states: 
Normal, Auto Halt, Quick Start, HALT/Grant Snoop and Deep Sleep states. The Auto Halt state 
provides a low-power clock state that can be controlled through the software execution of the HLT 
instruction. The Quick Start state provides a very low power and low exit latency clock state that can be 
used for hardware controlled “idle” computer states. The Deep Sleep state provides extremely low-
power states that can be used for “Power-On-Suspend” computer states, which is an alternative to 
shutting off the processor’s power. The exit latency of the Deep Sleep state is 30 msec in the Mobile 
Intel Celeron Processor. Performing state transitions not shown in Figure 1 is neither recommended nor 
supported. Figure 2 provides the clock state characteristics, which are described in detail in the following 
sections. 
2.2.2 Normal 
State 
The Normal state of the processor is the normal operating mode where the processor’s core clock is 
running and the processor is actively executing instructions.  
2.2.3 Auto 
Halt 
State 
This is a low-power mode entered by the processor through the execution of the HLT instruction. A 
transition to the Normal state is made by a halt break event (one of the following signals going active: 
NMI, INTR, BINIT#, INIT#, RESET#, FLUSH#, or SMI#).
