16-bit 16-bit microcomputers are microcomputers that use 16-bit microprocessors. A 16-bit register can store 216 different values. The range of integer values that can be stored in 16 bits depends on the integer representation used. With the two mo ...

microcontroller family, first introduced in 2007. The XE166 can be found in applications like servo drivers, appliance motors, industrial pumps, transportation and

power supplies A power supply is an electrical device that supplies electric power to an electrical load. The main purpose of a power supply is to convert electric current from a source to the correct voltage, current, and frequency to power the load. As a res ...

Key features

The XE166 family uses the Infineon/STMicroelectronics proprietary C166

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.

Architecture

CPU

The

central processing unit A central processing unit (CPU), also called a central processor, main processor or just Processor (computing), processor, is the electronic circuitry that executes Instruction (computing), instructions comprising a computer program. The CPU per ...

(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

* One or two analog to digital converters with up to 30 channels, 600 ns conversion time, up to 10 or 12-bit resolution * up to four units for PWM generation (CCU6) with 16-bit resolution * up to 6 CAN nodes with up to 256 message objects * up to 10 Universal Serial Interface Controller channels for software-defined serial interfaces (SPI, UART, I2C, I2S...) * External bus unit

Development tools

Evaluation kits

There are "Easy Kits" for evaluation of the controller features and "Application Kits" as a quick start for specific applications available.XE166 Easy Kits and Application Kits
The main applications are in the industrial field, like electric motor control, automation and solar inverters.
