Real-time clocks
AiP1302 is a trickle-charge timekeeping chip with a 3-wire interface (DS1302 type). AiP1307 is an I²C real-time clock with 56 bytes of SRAM (DS1307 type). AiP8563 is an I²C real-time clock / calendar (PCF8563 type).
Timer
AiP555 is a general-purpose timer for astable and monostable circuits (NE555 type).

Questions buyers ask
- Is AiP1307 compatible with DS1307 code?
- It uses an I²C interface with a BCD clock / calendar and 56 bytes of SRAM like the DS1307. Confirm register map and crystal requirements in the datasheet before reusing firmware.
