The CC2340R5-Q1 SimpleLink™ Wireless MCU contains an Arm® Cortex®-M0+ system CPU, which runs the application, the protocol stacks, and the radio. The Cortex-M0+ processor is built on a highly area and power optimized 32-bit processor core, with a 2-stage pipeline Von Neumann architecture. The processor delivers exceptional energy efficiency through a small but powerful instruction set and extensively optimized design, providing high-end processing hardware including a single-cycle multiplier. The Cortex-M0+ processor offers multiple benefits to developers including:

• Ultra-low power, energy efficient operation
• Deterministic, high-performance interrupt handling for time-critical applications
• Upward compatibility with the Cortex-M processors family

The Cortex-M0+ processor provides the excellent performance expected of a modern 32- bit architecture core, with higher code density than other 8-bit and 16-bit microcontrollers. Its features include the following:

• ARMv6-M architecture optimized for small-footprint embedded applications
• Subset of Arm Thumb/Thumb-2 mixed 16- and 32-bit instructions delivers the high performance expected of a 32-bit Arm
• Single-cycle multiply instruction
• VTOR supporting offset of the vector table base address
• Serial Wire debug with HW break-point comparators
• Ultra-low-power consumption with integrated sleep modes
• SysTick timer
• 48 MHz operation
• 0.99 DMIPS/MHz

Additionally, the CC2340Rx devices are compatible with all ARM tools and software.
