Intel 发布更多的Atom处理器

Intel 最新的Z5xx 系列Atom处理器采用了更大的封装。新系列的"P" and "PT" Atoms 被用来设计为工业，自动化，交通运输等领域。它们拥有更大的散热面积，可以在
-40 to 85 deg. C (-40 to 185 deg. F)的温度范围下使用。

Intel's original Z5xx processors, such as the 1.1GHz Z510 and 1.6GHz Z530, were designed to be as small as possible, offering a 14 x 13mm package and a 0.5mm ball pitch. The newly announced "P" and "PT" parts are "larger footprint" versions, but delivered in a 22 x 22mm package using 1.0mm ball pitch, according to the company.

The new parts are architecturally identical to their forebears, with the same clock speeds, same amount of second-level cache, and the same TDPs. But, the new Atoms include integrated heat spreaders, making them more suitable to "thermally constrained fanless applications," and "ideal for designs without small space restrictions," according to Intel.

The Atom Z530P is clocked at 1.6GHz, offering hyperthreading, a 512K second-level cache, 533MHz FSB (frontside bus), and a 2.2 Watt TDP. Meanwhile, the Atom Z510P has the same TDP, but with a 1.1GHz clock speed, 400MHz FSB, and no hyperthreading, according to Intel.

The Z530P and Z510P have a rated operating range of 0 to 60 deg. C (32 to 140 deg. F), like previous Atoms. Also available, though, are the Z530PT and Z510PT, rated for an industrial operating range from -40 to 85 deg. C (-40 to 185 deg. C).

To go with its new "P" and "PT" Atoms, Intel also unveiled new versions of the SCH US15W companion chip, which combines northbridge and southbridge functionality. The SCH US15WP and US15WPT are identical architecturally to the original "Pouslbo" chip, but instead of measuring 22 x 22mm, they take up 37.5 x 37.5mm. Again, easier cooling is touted, and the "T" extension to the part number denotes an industrial operating range。
