The 'C166 family[1]' is a 16-bit microcontroller architecture from Infineon (formerly the semiconductor division of Siemens) in cooperation with STMicroelectronics. It was first released in 1993 and is as controller for measurement and control tasks. It uses the well-establied RISC concept, but features some microcontroller-specific extensions such as bit-addressable memory and an interrupt system optimized for low-latency. When this architecture has been introduced the main focus has been to replace 8051 controllers (from Intel).
Opcode[2] compatible successors of the C166 family are the C167 family, XC167 family, the XE2000 family and the XE166 family.

The C167 family[3] is a further development of the C166 family. It has a further expanded addressing mode. Variants include for example Controller Area Network.
