The DSC6011CE2A-PROGRAMMABLE is marked Obsolete by Microchip.
The 1.71V to 3.63V supply range lets it run on a 1.8V, 2.5V, or 3.3V rail without a separate regulator. AEC-Q100 qualification means it was originally intended for automotive environments – think engine control modules, infotainment, or ADAS sensor clocks that see -20°C to 70°C ambient.
