Product Description

CORE I5-540UM SLBUJ Processor , Mobile Device Processors(3MB Cache, 1.2 GHz)-Notebook CPU

The Core i5-540UM is the second ultra-low voltage (ULV) microprocessor from i5-5xx line of mobile CPUs. This processor was introduced 4 months after the release of previous ULV model, Core i5-520UM. As expected, the 540UM has higher clock frequency - 1.2 GHZ as opposed to 1.06 GHz on the 520UM. In all other aspects both models are indistinguishable from each other. The i5-540UM has two CPU cores, and each core integrates its own level 1 and level 2 caches. The cores use shared 3 MB level 3 cache, that, beside storing infrequently used data, also duplicates the contents of L1 and L2 caches. The cores and the L3 cache are located on a single die, manufactured on 0.032 micron process. The CPU package also houses the second die with dual-channel memory and graphics controllers, made using 0.045 micron process. The package itself is a micro-BGA, and, as became standard for AMD and Intel mobile processors, does not have integrated heat spreader.
