In addition to being interoperable with common ARM ecosystem components, the devices come pre-loaded with libraries, including drivers for their various peripherals.

● Capabilities

The MSP432P401RIPZR is a versatile and powerful microcontroller that can be used in many settings thanks to its extensive capabilities. Notable features of this microcontroller include:

● High-Performance Processing

The MSP432P401RIPZR’s high-performance processing is provided by its ARM Cortex-M4F core, which allows it to swiftly and efficiently complete even the most demanding calculations and data-processing operations. The microcontroller has a maximum frequency of 48 MHz, allowing it to handle various tasks easily.

The MSP432P401RIPZR can talk to the outside world via several different channels. The microcontroller’s ability to talk to various gadgets and extras makes it a versatile tool.

● Low-Power Operation

The MSP432P401RIPZR has low-power modes that are great for applications that run off batteries. Because of the microcontroller’s ability to function on very little power, the battery life in portable devices can be increased while power consumption is decreased.

● Integrated DMA Controller

With the built-in DMA controller, data may be transferred quickly and efficiently between the system’s peripherals and memory, easing the burden on the CPU and boosting performance.

Detailed Description

Using the advanced mixed-signal features of the TI MSP430 along with the processing power of the ARM 32-bit Cortex-M4 RISC engine, the MSP432P401x microcontroller is a potent combination. The microcontrollers are compatible with most of the components found in the ARM ecosystem and come with a collection of preinstalled drivers.

Processor and Execution Features

Regarding computational performance and interrupt responsiveness, the Cortex-M4 processor provides a high-quality, low-cost platform while meeting system criteria such as minimal memory implementation, reduced pin count, and low power consumption. The Thumb® -2 processor, with its mixed 16- and 32-bit instruction set, provides the excellent performance typical of 32-bit ARM cores in the small memory footprint more commonly seen in 8- and 16-bit devices (typically in the range of a few kilobytes of memory needed for microcontroller-class applications). The Cortex-M4 CPU in the MSP432P401x MCUs may operate at up to 48 MHz, providing great performance for the intended category of applications while still preserving ultra-low active power consumption.

● Floating-Point Unit

A strongly connected floating-point unit exists in the MSP432P401x MCUs’ Cortex-M4 CPU (FPU). The FPU is a single-precision floating-point module that can perform arithmetic operations such as adding, subtracting, multiplying, dividing, adding, and accumulating, as well as the square root function. Floating-point constant instructions and fixed-point to floating-point data conversion are also provided.

● Memory Protection Unit

MSP432P401x MCUs have a Cortex-M4 processor with an embedded, tightly connected memory protection unit (MPU) that can handle up to eight protection regions. The MPU can be used by programs to enact memory access restrictions and memory privilege rules that partition processes from one another. These capabilities are generally necessary for operating system management.

● Nested Vectored Interrupt Controller (NVIC)

The NVIC supports up to sixty-four interruptions at eight distinct interrupt priority levels. The low latency, efficient interrupt and event handling, and smooth integration with device-level power-control methods are all made possible by the Cortex-M4 NVIC’s architecture.

● SysTick

The SysTick system timer built into the Cortex-M4 provides a straightforward 24-bit clear-on-write decrementing wrap-on-zero counter with various configurable options. The counter has multiple applications; the most common are in the realm of operating systems and the form of an all-purpose alarm system.

Debug and Trace Features

Ideal for microcontrollers and other small-package devices, the Cortex-M4 processor implements a complete hardware debug solution and gives high system visibility of the processor and memory via a typical 4-pin JTAG interface or a 2-pin Serial Wire Debug (SWD) connector. To facilitate a smooth transition between 2-pin and 4-pin modes of operation, the SWJ-DP interface integrates the SWD and JTAG debug ports into a single module.

The CPU includes an Instrumentation Trace Macrocell (ITM), data watchpoints, and a profiling unit for system tracing. A Serial Wire Viewer (SWV) exports a stream of software-generated messages, data trace, and profiling information over a single pin, allowing for easy and inexpensive profiling of the system trace events.

● Interrupts

MSP432P401x MCUs feature a Cortex-M4 processor, which includes an NVIC with 64 external interrupt lines and 8 priority levels. From an application’s point of view, two types of interrupt sources can be generated by a device: NMI interrupts, and User Interrupts. The CPU follows a fixed and programmable order of precedence for handling internal and external events that can cause exceptions, such as CPU instruction, memory, and bus fault conditions. The specifics of handling different exceptions are described below (including CPU reset and fault models).

● System Control

System Control comprises the modules that manage the device’s overall operation, such as its power settings, operating modes, clocks, reset handling, and user preferences.

Device Resets

The MSP432P401x MCUs support many types of resetting. During code development and debugging, the application developer might initiate different resets based on reset needs because each class results in a distinct level of initiation of device logic. The various device reset classes are discussed below.

● Power On/Off Reset (POR)

Initiating a full initialization of the application and device configuration data is what the POR does. Any of the Power System Supervisor, Power Control Module, Clock System on DCO external resistor short circuit error, or Device Emulation Logic can trigger this type of reset (through the debugger). No matter the origin of the POR, the device is reset to the same basic configuration from the standpoint of the application.

● Reboot Reset

The Reboot Reset is functionally equivalent to the POR and can be used by the program to simulate a reset of the POR class without a hardware reset or the use of the RSTn pin. It can also be started via the debugger and has no effect on the debug connection. Conversely, a debug disconnect occurs when a POR occurs.

● Soft Reset

Only the no debug logic in the Cortex-M4, and the WDT A are reset by the Soft Reset, leaving the rest of the system in its original state. This reset will not interfere with any other parts of the system. The MSP432P401x MCUs support up to 16 Soft Reset sources.
