I am currently designing with Texas Instruments microcontrollers and I trust them for low power applications specifically for those applications running on batteries. I think their ultra low power microcontrollers with Code composer studio which has in-built ULP advisory(not to mention GRACE too) is best for creating power controlled products. By this poll I want too know what you guys choose or prefer for low power designs? or Am I missing something already which I should have considered for power specific products? Please give your suggestions too.
