Using the Newest gen ARM, Part III

The continuing saga of the 0.4 mm pitch KL03 ARM microcontroller. If you haven't yet done so, read part I, and part II. Today, I have a look at the good, the bad, and the ugly - or more accurately,... Read more

Using the Newest gen ARM Microcontrollers

I've written a few times about the new Freescale KL03 ARM Cortex M0+ microcontroller. This particular part comes only in very small packages, with the smallest being a 1.6mm x 2mm WLCSP (wafer level, chip scale package) 0.4mm pitch, 20... Read more

Do you Need that Part? Or, is it Just Habit?
