help me please I need converter 3V to 5V for PIC MCU

[marki]

I have battery 1.5 V serise to 3V. I need converter to 5 V for PIC MCU or MCS-51 MCU

thank you very much

Also make it confirm that you really need 5V. Why don't you try it at 3V ? You can save power on low voltage.

Microchip has PIC variants that work between 2V and 5.5V. For example the PIC16LF87xA series. The only limit is the clock frequency is max 4MHz, or 3-5.5V @10MHz

There are a lot of PIC parts that will run at 3V. If you do not already have a part specified, go to the Microchip Advanced Part Selector (MAPS) page and select a part that meets your needs. If you do have a part that you need to use but it only runs at 5V, there may be a pin compatible part that runs at 3V.

For some pics even the 5 V part will work in 3 volts, but with lower speed
