Detailed Description

6.1

Overview

The MSP432P4x1x microcontroller is an ideal combination of the TI MSP430 low-power DNA, advance

mixed-signal features, and the processing capabilities of the Arm 32-bit Cortex-M4 RISC engine. The

microcontrollers ship with bundled driver libraries and are compatible with standard components of the

Arm ecosystem.

6.2

Processor and Execution Features

The Arm Cortex-M4 processor provides a high-performance low-cost platform that meets system

requirements of minimal memory implementation, reduced pin count, and low power consumption, while

delivering outstanding computational performance and exceptional system response to interrupts. The

Thumb®-2 mixed 16- and 32-bit instruction set of the processor delivers the high performance that is

expected of a 32-bit Arm core in a compact memory size usually associated with 8- and 16-bit devices

(typically in the range of a few kilobytes of memory needed for microcontroller-class applications).

In MSP432P4x1x devices, the Cortex-M4 processor can run up to 48 MHz, delivering high performance

for the targeted class of applications, while at the same time maintaining ultra-low active power

consumption.

6.2.1

Floating-Point Unit (FPU)

The Cortex-M4 processor on MSP432P4x1x devices includes a tightly coupled FPU. The FPU is an

IEEE 754 compliant single-precision floating-point module supporting add, subtract, multiply, divide,

accumulate, and square-root operations. The FPU also provides conversion between fixed-point and

floating-point data formats and floating-point constant instructions.

6.2.2

Memory Protection Unit (MPU)

The Cortex-M4 processor on MSP432P4x1x devices includes a tightly coupled MPU that supports up to

eight protection regions. Applications can use the MPU to enforce memory privilege rules that isolate

processes from each other or enforce memory access rules. These features are typically required for

operating system handling purposes.

6.2.3

Nested Vectored Interrupt Controller (NVIC)

The NVIC supports up to 64 interrupts with eight levels of interrupt priority. The Cortex-M4 NVIC

architecture allows for low latency, efficient interrupt and event handling, and seamless integration to

device-level power-control strategies.

6.2.4

SysTick

The Cortex-M4 includes an integrated system timer, SysTick, which provides a simple, 24-bit, clear-on-

write, decrementing, wrap-on-zero counter with a flexible control mechanism. The counter can be used in

several different ways, and it is typically deployed either for use by the operating system or as a general-

purpose alarm mechanism.

6.2.5

Debug and Trace Features

The Cortex-M4 processor implements a complete hardware debug solution and provides high system

visibility of the processor and memory through either a traditional 4-pin JTAG port or a 2-pin Serial Wire

Debug (SWD) port, which is ideal for microcontrollers and other small-package devices. The SWJ-DP

interface combines the SWD and JTAG debug ports into one module, which allows a seamless switch

between the 2-pin and 4-pin modes of operation, depending on application needs.
