The C166 family is a 16-bit microcontroller architecture from
Infineon
Infineon Technologies AG is a German semiconductor manufacturer founded in 1999, when the semiconductor operations of the former parent company Siemens AG were spun off. Infineon has about 50,280 employees and is one of the ten largest semicond ...
(formerly the semiconductor division of Siemens) in cooperation with
STMicroelectronics. It was first released in 1990 and is a controller for measurement and control tasks. It uses the well-established RISC architecture, but features some microcontroller-specific extensions such as bit-addressable memory and an interrupt system optimized for low-latency. When this architecture was introduced the main focus was to replace
8051 controllers (from
