Datasheet

Commonly used terms are explained here for clarification:

• Intel Celeron Processor 200 Sequence — Single core processor in the FC-BGA6 

package with a 512 KB L2 cache.

• Processor — For this document, the term processor is the generic form of the Intel 

Celeron processor 200 sequence. The processor is a single package that contains 

one exectution unit.

• Keep-out zone — The area on or near the processor that system design can not 

use. 

• Processor core — Processor core die with integrated L2 cache. 
• FSB (Front Side Bus) — The electrical interface that connects the processor to 

the chipset. Also referred to as the processor system bus or the system bus. All 

memory and I/O transactions as well as interrupt messages pass between the 

processor and chipset over the FSB.

• 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 pins 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.

• Functional operation — Refers to normal operating conditions in which all 

processor specifications, including DC, AC, system bus, signal quality, mechanical 

and thermal are satisfied. 

• Execute Disable  Bit — The Execute Disable bit allows memory to be marked as 

executable or non-executable, when combined with a supporting operating system. 

If code attempts to run in non-executable memory the processor raises an error to 

the operating system. This feature can prevent some classes of viruses or worms 

that exploit buffer over run vulnerabilities and can, thus, help improve the overall 

security of the system. See the Intel

®

 Architecture Software Developer's Manual 

for more detailed information.

• Intel

 64 Architecture — An enhancement to Intel's IA-32 architecture, allowing 

the processor to execute operating systems and applications written to take 

advantage of the Intel

®

 64 architecture. Further details on Intel
