Summary of Basic Features

The XC2000 devices are enhanced members of the Infineon family of full featured 16-bit

single-chip CMOS microcontrollers. The XC2000 combines the extended functionality

and performance of the C166SV2 Core with powerful on-chip peripheral subsystems

and on-chip memory units and provides several means for power reduction.

The following key features contribute to the high performance of the XC2000:

High Performance 16-bit CPU with Five-Stage Pipeline and MAC Unit

• Single clock cycle instruction execution

• 1 cycle minimum instruction cycle time (most instructions)

• 1 cycle multiplication (16-bit

× 16-bit

• 4 + 17 cycles division (32-bit / 16-bit), 4 cycles delay, 17 cycles background execution

• 1 cycle multiply and accumulate instruction (MAC) execution

• Automatic saturation or rounding included

• Multiple high bandwidth internal data buses

• Register-based design with multiple, variable register banks

• Two additional fast register banks

• Fast context switching support

• 16 Mbytes of linear address space for code and data (von Neumann architecture)

• System stack cache support with automatic stack overflow/underflow detection

• High performance branch, call, and loop processing

• Zero-cycle jump execution

Control Oriented Instruction Set with High Efficiency

• Bit, byte, and word data types

• Flexible and efficient addressing modes for high code density

• Enhanced boolean bit manipulation with direct addressability of 6 Kbits for peripheral

control and user-defined flags

• Hardware traps to identify exception conditions during runtime

• HLL support for semaphore operations and efficient data access

Power Management Features

• Two IO power domains fulfill system requirements from 3 V to 5 V

• Separately controllable core power domains support wake-up via external triggers or

on-chip timer while drastically reducing the power consumption

• Gated clock concept for improved power consumption and EMC

• Programmable system slowdown via clock generation unit

• Flexible management of peripherals, can be individually disabled

• Programmable frequency output
