• Manufacturer Part Number: sak-xc2264m-72fxxl
• Description: 16/32-bit Single-chip Microcontroller With 32-bit Performance
• Manufacturer: Infineon Technologies Corporation

3.3
The core of the CPU consists of a 5-stage execution pipeline with a 2-stage instruction-
fetch pipeline, a 16-bit arithmetic and logic unit (ALU), a 32-bit/40-bit multiply and
accumulate unit (MAC), a register-file providing three register banks, and dedicated
SFRs. The ALU features a multiply-and-divide unit, a bit-mask generator, and a barrel
shifter.
