What logic family does NXP 1114 MCU belongs to?
The digital interface pins are defined as:


logic low output as maximum \$0.4V\$, and logic high output as minimum \$V_{DD} - 0.4V\$
logic low input as maximum \$0.3 \times V_{DD}\$,  and logic high input as maximum \$0.7 \times V_{DD}\$


At a glance, the voltage levels appear similar to LVCMOS.
