That means it is still available for existing production runs, but ST will not support new design-ins.
The analog front end is unusually capable for an 8-bit part: 25 channels of 12-bit ADC and a single 12-bit DAC, which lets it handle sensor acquisition and actuator drive without external converters.
Housed in a 48-LQFP (7x7 mm) package with 41 I/O pins. Surface-mount only.
It is not fully discontinued — existing production can still be supported through the independent channel — but ST will not accept new design registrations. For new designs, evaluate a current-production STM8A variant with equivalent Flash and analog density.
Yes, the STM8AL3L68TCY is part of the Automotive, AEC-Q100, STM8A series, qualified for automotive-grade reliability and temperature range.
