I'm working on my senior design project where I'm expected to build a PCB for a wearable device. We were shown an existing prototype that was built using the teensy 3.1 development board which host an MK20DX256 chip which has a 32 bit ARM Cortex-M4 (72 MHz). I was hoping to replace the current MCU with something with a similar core and Bluetooth Low Energy transceiver. I was looking the chips in the k series but the drop-off in processor speed seems huge. If anyone can help give some direction.
The Kinetis KW2 runs at 50Mhz and has a thinner package than the KW20 series, this allows a better footprint and a thinner overall application packaging. The change in clock speed must be compensated by a more efficient running code.
