The Infineon XE166 family is a 16-bit microcontroller family, first introduced in 2007. The XE166 can be found in applications like servo drivers, appliance motors, industrial pumps, transportation and power supplies.

Key features
The XE166 family uses the Infineon/STMicroelectronics proprietary C166 16-bit core in a version which also contains a 32-bit MAC unit. Core frequency ranges from 40 to 100 MHz, embedded flash from 32 KB to 1.6 MB, and RAM up to 138 KB. The microcontroller, containing an embedded voltage regulator, can run from a single power supply between 3 and 5 V.
CPU
The central processing unit (CPU) of the XE166 microcontroller family is principally fetching and decoding instructions, to supply, perform operations and store calculated result on the operands for the arithmetic logic unit (ALU) and the MAC unit.
As the CPU is the main engine of the XE166 microcontroller, it is also affected by certain actions of the peripheral subsystem. Because a five-stage processing pipeline (plus two-stage fetch pipeline) is implemented in the XE166, up to five instructions can be processed in parallel. Most instructions of the XE166 are executed in a single clock cycle due to this parallelism.
Peripherals
Evaluation kits
There are "Easy Kits" for evaluation of the controller features and "Application Kits" as a quick start for specific applications available. The main applications are in the industrial field, like electric motor control, automation and solar inverters.
