Samsung made the first A5 chips. Then, however, TSMC will reportedly ramp the A5 in Q3 or Q4, according to sources. TSMC could be a second source to Samsung for the 45- and 40-nm version. Then, TSMC will fab the 28-nm version, sources said.
On the other hand, TSMC and GlobalFoundries both make Snapdragon for Qualcomm, which is used to power the HTC phones competing with Iphone. So I don't see why ultimately Apple won't use both Samsung and TSMC. Ultimately it can impose capacity burden on competing products at least indirectly.
What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
