Lots of m4 options are available now. The difference is really going to come down to power mode and/or peripheral function differentiation. Additionally, the support for higher level functions to easy peripheral programming and firmware IP for functions like motor control will make a big difference. Lets see more about these topics in similar product announcements going forward.
For a part that samples soon, this has very little real information.
I did find this : ["The XMC4000 series has a cpu subsystem, dsp functionality, a floating point unit, a fast flash memory with 22ns read time and error correction code, large sram and extended peripheral functions. These include new timer modules; up to four parallel 12bit a/d converters with a sampling rate of 70ns and a conversion time of 500ns; up to two 12bit d/a converters, up to four high resolution PWM channels (150ps); and integrated delta-sigma demodulator modules and touch button modules. "]
and in their FAQ they claim this is NOT Automotive applications. (yet have multiple CAN bus?)
No prices, apart from a cryptic 1e to 7e indicator.
I wonder what 1e gets you ?
Google helped find a more complete chip-analysis here (needs translate)
and a road map here - just Google :
Hints that 1e@10k claim could be ?
Replay available now: A handful of emerging network technologies are competing to be the preferred wide-area connection for the Internet of Things. All claim lower costs and power use than cellular but none have wide deployment yet. Listen in as proponents of leading contenders make their case to be the metro or national IoT network of the future. Rick Merritt, EE Times Silicon Valley Bureau Chief, moderators this discussion.
