Here's the link given the last time:
La vigencia de la tarjeta de residencia de familiar de ciudadano de la Unión caducará por las ausencias superiores a seis meses en un año.
Translation: The validity of the residency card for a family member of a citizen of the Union will expire from absences superior to six months in one year.
This is taken off of the Spanish Ministry of the Interior website, and they're the ones in charge of issuing residency cards in Spain.
