9 Detailed Description

9.1 Overview

Section 4 shows the core modules of the CC2674P10 device.

Throughout this section, see the Technical Reference Manual listed in Section 11.2 for more details.

9.2 System CPU

The CC2674P10 SimpleLink™ Wireless MCU contains an Arm® Cortex®-M33 system CPU with TrustZone®,

which runs the application and the higher layers of radio protocol stacks.

The system CPU is the foundation of a high-performance, low-cost platform that meets the system requirements

of minimal memory implementation, and low-power consumption, while delivering outstanding computational

performance and exceptional system response to interrupts.

Its features include the following:

• ARMv8-M architecture with TrustZone® security extension optimized for small-footprint embedded

applications

• Arm Thumb®-2 mixed 16- and 32-bit instruction set delivers the high performance expected of a 32-bit Arm

core in a compact memory size

• 8 regions of non-secure memory protected regions

• 8 regions of secure memory protected regions

• 4 regions of Security Attribute Unit (SAU)

• Single-cycle multiply instruction and hardware divide

• Digital-signal-processing (DSP) extension

• IEEE 754-compliant single-precision Floating Point Unit (FPU)

• Fast code execution permits increased sleep mode time

• Deterministic, high-performance interrupt handling for time-critical applications

• Full debug with data matching for watchpoint generation

– Data Watchpoint and Trace Unit (DWT)

– JTAG Debug Access Port (DAP)

– Flash Patch and Breakpoint Unit (FPB)

• Trace support reduces the number of pins required for debugging and tracing

– Instrumentation Trace Macrocell Unit (ITM)

– Trace Port Interface Unit (TPIU) with asynchronous serial wire output (SWO)

• Optimized for single-cycle flash memory access

• Tightly connected to 8 kB 4-way random replacement cache for minimal active power consumption and wait

states

• Ultra-low-power consumption with integrated sleep modes

• 48 MHz operation
