Difference between nRF51822_xxAA and nRF51822_xxAC?

[la-ble]

I'm prompted to select the target device for a new uVision project. As far as I've found so far, they both are the larger memory variants (256KB).

AA is 256K flash/16K sram, AB is 128K flash/16K sram, AC is the new 256K flash/32K sram variant.

Be advised that Segger has a different set of correspondences when selecting what model to use. Even if you know which one you have by the variant number - watch for their listing. Currently in Ozone and JLink: AA = 516K flash / 64K RAM AB = 260K flash / 32K RAM
