Continuing our IC exploration, we decided to sneak a peak under the Jorjin cover. We uncovered a Texas Instruments WL1270B 802.11 b/g/n Wi-Fi solution.

According to Chipworks, the WL1270 is an older chip that was designed to work with the TI OMAP 3530. It's interesting that the Fire has it, given that it's coupled with the newer OMAP 4430.
