to maintain compatibility with SC242
(processor core frequencies (MHz):
266, 300, 300A, 333, 366, 400, 433).
— Plastic Pin Grid Array (PPGA) Package
(processor core frequencies (MHz):
300A, 333, 366, 400, 433, 466, 500).
Integrated high performance 32 KB
instruction and data, nonblocking, level-
one cache: separate 16 KB instruction and
16 KB data caches.
Integrated thermal diode.
The Intel
®
Celeron™ processor is designed for Value PC desktops and is binary compatible with
previous generation Intel architecture processors. The Intel
®
Celeron processor provides good
performance for applications running on advanced operating systems such as
Windows* 95/98, Windows* NT, and UNIX*. This is achieved by integrating the best attributes
of Intel processors—the dynamic execution performance of the P6 microarchitecture plus the
capabilities of MMX™ technology—bringing a balanced level of performance to the Value PC
market segment. The Intel
®
Celeron processor offers the dependability you would expect from
Intel at an exceptional value. Systems based on Intel
®
Celeron processors also include the latest
features to simplify system management and lower the cost of ownership for small business and
home environments.
