The '''MARC4''' was a [[microprocessor family|family]] of {{arch|4}} [[microcontroller]]s initially developed by [[Eurosil]] in the mid 1980s. Eurosil was later sold to [[Temic]] (TELEFUNKEN) and in 1998 was sold off to [[Atmel]] which continued to manufacture it well into the 2000s. The MARC4 targeted the ultra-low power and wireless market.
