MARC4 Family
no photo (ic).svg
Developer Eurosil, Temic, Atmel
Manufacturer Atmel, Eurosil
Type microcontrollers
Production 1985-2014
Architecture 4-bit, Harvard architecture
ISA MARC4
Word size 4 bit
0.5 octets
1 nibbles
Technology CMOS
Clock 32 kHz-8 MHz
Package SO16, SO20, SO24, SO28, SO44, QFP80

The MARC4 was a family of 4-bit microcontrollers 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.
