This line is more of an extension of Dialog's existing options, which were extremely limited, reconfigurable logic devices. Dialog sells the Greenpak devices as flexible interfaces, and for a variety of niche applications; I looked at them a number of times, but they're not as flexible as the marketing materials make them seem.
No sadness for Dialog, I'll never forgive them for the utter abominations that are their cheap Bluetooth LE micros… Cortex-M0 with an SWD debug interface, this should be just like an nRF51, right? Hahaha, no, it's completely proprietary undocumented garbage with a Dialog SDK burned in ROM and — get this — tiny one time programmable memory for the "application" (cost-cutting to the extreme?).
