STM8L101 clocking at < 2 MHz

Hello All, 

Is there any way to run STM8L101 at a frequency about 200 kHz to save some microAmps?

BR, Dmitry

Hi Dimitry,

The L101 only looks to have the internal 16MHz RC clock, so an external crystal is not possible. However, you could adjust the CLK_CKDIVR to 64 for a 250KHz clock.

Hope that helps.

Ian

Добрый день, Дмитрий

В stm8l101 �?огла�?но референ�? мануал не уда�?т�?�? уменьшить тактовую ча�?тоту ниже 2 МГц при и�?пользовании HSI (внутреннего RC генератора). Един�?твенна�? возможно�?ть уменьшени�? потреблени�? до микроампер �?то и�?пользовать режим Active-halt �?овме�?тно �? Auto-wakeup.
