1. CPU:
The ARM® Cortex®-M4 processor with floating-point unit (FPU) has a 32-bit instruction set (Thumb®-2
technology) that implements a superset of 16 and 32-bit instructions to maximize code density and
performance.
This processor implements several features that enable energy-efficient arithmetic and high-performance
signal processing including:
• Digital signal processing (DSP) instructions
• Single-cycle multiply and accumulate (MAC) instructions
• Hardware divide
• 8 and 16-bit single instruction multiple data (SIMD) instructions
• Single-precision floating-point unit (FPU)
The ARM Cortex Microcontroller Software Interface Standard (CMSIS) hardware abstraction layer for the
ARM Cortex processor series is implemented and available for the M4 CPU.
Real-time execution is highly deterministic in thread mode, to and from sleep modes, and when handling
events at configurable priority levels via the Nested Vectored Interrupt Controller (NVIC).
Executing code from flash will have a wait state penalty on the nRF52 Series. An instruction cache can be
enabled to minimize flash wait states when fetching instructions. For more information on cache, see Cache
on page 27. The section Electrical Specification on page 18 shows CPU performance parameters
including wait states in different modes, CPU current and efficiency, and processing power and efficiency
based on the CoreMark® benchmark.

2. Memory
The nRF52832 contains Flash and RAM that can be used for code and data storage
