MARC4 Micro-Controller

The MARC4 was a family of 4-bit micro controllers. They were first introduced by Eurosil, then bought by Temic (currently part of conti), and finally acquired by Atmel. The micro controllers had a 4-bit architecture and were designed with extremely low power consumption in mind. They were used in radio frequency communication devices, home automation and telemetry. They competed with the S1C6x in the same area of applications.
