The C166 family is a 16-bit microcontroller architecture from Infineon (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 Intel ).
5-735: Opcode-compatible successors of the C166 family are the C167 family, XC167 family , the XE2000 family and the XE166 family . As of 2017, microcontrollers using the C166 architecture are still being manufactured by NIIET in Voronezh , Russia, as part of the 1887 series of integrated circuits. This includes a radiation-hardened device under the designation 1887VE6T ( Russian : 1887ВЕ6Т ). The Siemens/Infineon C167 family or STMicroelectronics ST10 family
10-538: 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. 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
15-480: Is a stub . You can help Misplaced Pages by expanding it . XE166 family 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 . The XE166 family uses the Infineon/STMicroelectronics proprietary C166 16-bit core in
20-479: Is a further development of the C166 family . It has improved addressing modes and support for "atomic" instructions. Variants include, for example, Controller Area Network (CAN bus). C167 architecture is used predominantly on German and German-owned automobile marques as well as certain models from Renault, Dacia, Peugeot, Citroen, Hyundai, Kia etc. This microcomputer - or microprocessor -related article
25-500: 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
