The LPC43S6x operate at CPUfrequencies of up to 204 MHz.

The Arm Cortex-M4 is a 32-bit core that offers system enhancements such as low powerconsumption, enhanced debug features, and a high level of support block integration. TheArmCortex-M4 CPU incorporates a 3-stage pipeline, uses a Harvard architecture withseparate local instruction and data buses as well as a third bus for peripherals, andincludes an internal prefetch unit that supports speculative branching. The Arm Cortex-M4 supports single-cycle digital signal processing and SIMD instructions. Ahardware floating-point processor is integrated into the core.

The LPC43S6x include an application Arm Cortex-M0 coprocessor and a second Arm Cortex-M0subsystem for managing the SGPIO and SPI peripherals.The Arm Cortex-M0 coprocessor is anenergy-efficient and easy-to-use 32-bit core which is upward code- and tool-compatiblewith the Cortex-M4 core. The Cortex-M0 coprocessor, designed as a replacement forexisting 8/16-bit microcontrollers, offers up to 204 MHz performance with a simpleinstruction set and reduced code size. The Cortex-M0 coprocessor hardware multiply isimplemented as a 32-cycle iterative multiplier.
