 Good to hear - To help that advocacy, ask them about "full compliance with
ETSI specifications"
- marketing types love that style of phrase - Volts and uA have them glazing
over ...

This summary from a recent Infineon release (smart card sector) :

"  130nm process SLE88CFX4000P : 80 KBytes of "hidden" ROM, 400 KBytes of
EEPROM/Flash,
16 KBytes of RAM, 32 Bit CPU, crypto co-processor.
 It operates at a voltage range of 1.62 to 5.5 V, in full compliance with
ETSI specifications. "

 Strikes me that getting a 130nm device to operate 1.65-5.5V is not trivial,
but it must
have been important enough for them to make the effort.

 Besides the process/ETSI tag point, this device would make a good secure
FPGA
Bootloader, if  Infineon decided to package for that market.
