Hi @QJ_HAPPY,
In the RM rev.14 (Table 39-4 Module operation in available power modes), you can see that LPI2C is fully-functional in STOP2, and it supports Async operations in STOP1 and VLPS.
Fully-functional means that LPI2C can send the commands in the TX FIFO and receive data.
Table 52-10 & Table 52-11 list wakeup interrupts.
BR, Daniel
