1.3 Description

The SimpleLink MSP432P401x microcontrollers (MCUs) are optimized wireless host MCUs with an

integrated 14-bit analog-to-digital converter (ADC) capable of up to 16 ENOB delivering ultra-low-power

performance including 80 µA/MHz in active power and 660 nA in standby power with FPU and DSP

extensions. As an optimized wireless host MCU, the MSP432P401x allows developers to add high-

precision analog and memory extension to applications based on SimpleLink wireless connectivity

solutions.

The MSP432P401x devices are part of the SimpleLink microcontroller (MCU) platform, which consists of

Wi-Fi®,Bluetooth®low energy, Sub-1 GHz, and host MCUs. All share a common, easy-to-use

development environment with a single core software development kit (SDK) and rich tool set. A one-time

integration of the SimpleLink platform lets you add any combination of devices from the portfolio into your

design. The ultimate goal of the SimpleLink platform is to achieve 100 percent code reuse when your

design requirements change. For more information, visit www.ti.com/simplelink.

MSP432P401x devices are supported by a comprehensive ecosystem of tools, software, documentation,

training, and support to get your development started quickly. The MSP-EXP432P401R LaunchPad

development kit or MSP-TS432PZ100 target socket board (with additional MCU sample) along with the

free SimpleLink MSP432 SDK is all you need to get started.

1.4 Functional Block Diagram

Figure 1-1 shows the functional block diagram of the MSP432P401R and MSP432P401M devices.

Figure 1-1. MSP432P401R, MSP432P401M Functional Block Diagram

The CPU and all of the peripherals in the device interact with each other through a common AHB matrix.

In some cases, there are bridges between the AHB ports and the peripherals. These bridges are

transparent to the application from a memory map perspective and, therefore, are not shown in the block

diagram.

3 Device Comparison

Table 3-1 summarizes the features of the MSP432P401x microcontrollers.

(1) For the most current part, package, and ordering information for all available devices, see the Package Option Addendum in Section 9, or see the TI website at www.ti.com.

(2) Each number in the sequence represents an instantiation of Timer_A with its associated number of capture/compare registers and PWM output generators available. For example, a

number sequence of 3, 5 would represent two instantiations of Timer_A, the first instantiation having 3 and the second instantiation having 5 capture/compare registers and PWM output

generators, respectively.

Figure 4-3 shows the pinout of the 64-pin RGC package.

A. The secondary digital functions on Ports P2, P3, and P7 are fully mappable. This pinout shows only the default

mapping. See Section 6.9.2 for details.

B. A glitch filter is implemented on these digital I/Os: P1.0, P1.4, P1.5, P3.0, P3.4, P3.5, P6.6, P6.7.

C. TI recommends connecting the thermal pad on the QFN package to DVSS.

D. UART BSL pins: P1.2 - BSLRXD, P1.3 - BSLTXD

E. SPI BSL pins: P1.4 - BSLSTE, P1.5 - BSLCLK, P1.6 - BSLSIMO, P1.7 - BSLSOMI

F. I2C BSL pins: P3.6 - BSLSDA, P3.7 - BSLSCL
