[SOLVED] 1.5v power for a microcontroller

[KellyB]

Hello,
I am a completely new user of building electronics, so please forgive my ignorance. I would like to know if there are microcontrollers available that can be powered by a single AA or AAA (1.5v) battery? The only function it will need to control is the illumination of bi-colored LEDs at a specific frequency. It will likely only run for <1 hour / week and be complete shut off in between.
Any help / advice would be much appreciated.
Thank you very much in advance.
Kelly

hi

also look at silabs and ti MSP430.
the silabs people claims to work their MCU at 0.9V

You have so many solutions.
You can check SH66L06A(sinowealth), Winbond or Tenx. and the cost I mentioned is around USD0.1.
The only doubt is how to drive LED with single 1.5V battery.
