I am using

STM8L051F3

for my project. My project uses 10 LEDs, Timer2 and 1 input Pin. After getting input from 1 pin i will on the LEDs 1 by 1. System powered with battery so run time current should be minimum. Without using sleep, Halt how can i run the system at lowest power. Please guide me through this.

To extremal minimize power consumption with working processor  you can copy executable code to RAM and switch off FLASH, clocking the processor from LSI.  In any case you need to detailed study the manuals. Unfortunately I can not show for you example program.

Okk thanks, I have another query, I have STM8L051F3 and it has not LCD controller. I am looking for low power,low cost controller with LCD controller inside. ST MCU finder doesnt help to find which controller has LCD controller inside and low power and low cost. I searched some of them but i need your opinion  and recommandation.
