003V SOT23-6 What is this component
It looks like a PIC10F200. The datasheet describes the marking code as having two characters of 'customer specific information', and two of 'alphanumeric traceability code', but in practice the first two digits appear to be the last two digits of the part number ('00' for PIC10F200) and last two are 'random'.  



Here are some vendors' images of what purport to be a PIC10F200.
