Hi, I am looking at the NXP Bluetooth Low Energy system-on-chips and was wondering if someone could help. I am looking for the lowest possible power consumption, but am unsure which processor to go for. I only need very short range and low data rates and I don't need a huge amount of processing power.
Lookign at the specs, the QN9080 seems the lowest power. Is this right? I notice is has a Cortex M4 rather than an M0/M0+ in it, which would be a nice thing to have for future upgrades. Does the M4 use a lot more power than the M0 family for the same clock/program?
