Introduction
The Intel Celeron D processor 300 sequence on 90 nm process and in the 775-land package is a
follow-on to the Intel Celeron D processor in the 478-pin package. This processor uses Flip-
Chip Land Grid Array (FC-LGA4) package technology, and plugs into a 775-land LGA socket,
referred to as the LGA775 socket. LGA775 is required to support higher frequency processors.
This next generation of socket provides longevity for processor support beyond 2004. LGA775
designs support the Celeron D processor providing great flexibility and breadth of processor
choices.
The Intel Celeron D processor 300 sequence on 90 nm process in the 775-land package supports
Intel Extended Memory 64 Technology (Intel EM64T)
Φ
as an enhancement to Intel’s IA-32
architecture. This enhancement enables the processor to execute operating systems and
applications written to take advantage of Intel EMT64T. With appropriate 64 bit supporting
hardware and software, platforms based on an Intel processor supporting Intel EM64T can enable
use of extended virtual and physical memory. Further details on the 64-bit extension architecture
and programming model is provided in the Intel Extended Memory 64 Technology Software
Developer Guide at http://developer.intel.com/technology/64bitextensions/.
Note:
In this document the Celeron D processor on 90 nm process and in the 775-land package is also
referred to as Celeron D processor in the 775-land package or as the “processor”.
Note:
In this document, unless otherwise specified, the Intel Celeron D processor 300 sequence refers
to Intel Celeron D processors 355, 351, 345J/346, 340J/341, 335J/336, 330J/331, and 325J/326.
Note:
Intel Celeron D processors 355, 351, 346, 341, 336, 331, and 326 support Intel Extended
Memory 64 Technology (Intel EM64T)
The Celeron D processor in the 775-land package, like its predecessor, the Celeron D processor in
the 478-pin package, is based on the same Intel 32-bit microarchitecture and maintains the tradition
of compatibility with IA-32 software. It maintains the same Front Side Bus (FSB) data transfer
speed at 533 MT/s and Level 2 cache size of 256 KB.
The Celeron D Processor in the 775-Land Package includes the Execute Disable Bit capability
previously available in Intel Itanium processors. This feature, combined with a supported
operating system, allows memory to be marked as executable or nonexecutable. If code attempts to
run in non-executable memory, the processor generates an error to the operating system. This
feature can prevent some classes of viruses or worms that exploit buffer overrun 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 will enable support components for the processor including heatsink, heatsink retention
mechanism, and socket. Manufacturability is a high priority; hence, mechanical assembly may be
completed from the top of the baseboard and should not require any special tooling.
The processor includes an address bus powerdown capability that removes power from the address
and data pins when the FSB is not in use. This feature is always enabled on the processor.
