3. Applications need to operate off batteries, or draw minimal power
Top Customer Problems
… Solved!
Increased Processing Capability
32-bit 48-MHz Cortex M4F provides 2x more performance than M3, at ½ the power
Customers are adding functionality requiring higher data throughput and integration, and/or standardizing on ARM
Industry’s lowest power general purpose Cortex M device allows for 95uA/MHz of active power and 850nA of standby power
Low Power Operation
Applications need to operate off batteries, or draw minimal power
Customers want tools and software that maximizes their product’s performance, minimizes power, and simplifies code development
Extract MSP power efficiency and ARM® performance through easy-to-use hardware and software tools
Tools & Ease of Use
What kinds of problems are customers looking to solve. Many times we see customers looking for increased processing capability. They want to add more capability into their device, or throughput or analog performance or perhaps they are standardizing on ARM. They also want low power operations, especially when they are battery powered or needing to draw just a minimal amount of line power. They want the tools and software to be easy to use and to help them optimize their performance and also their power. And they want a scalable portfolio that allows them to move between low power and high performance products. MSP432 solves these problems with a 32-bit 48 MHz Cortez -M4F processor which gives you more performance, in fact twice the performance of an M3 and half the power. Low power operation is part of MSP's DNA. We've designed this device to be the lowers power general purpose Cortex-M device. With only 95 uA/MHz of Active Power and 850nA of Stand By including RTC. We want users to take advantage of MSP430 tool chain as well as the ARM tool chain which will allow you to optimize for high performance and for low power. Now users can choose between 16-bit products and 32-bit products all that have seamless portability.
Achieve seamless portability between MSP’s 16-bit and 32-bit portfolio
Scalability
Customers want flexibility to scale between ultra-low power and high performance, while maintaining portability

4. Increased processing capability
Selecting the highest performance Cortex M core
48MHz ARM Cotex M4F
Full ARM instruction set (> M0+, M3,M4)
DSP extensions (M3 vs M4)
FPU engine (M4 vs M4F)
Incorporating high performance peripherals and features
Driver Lib in ROM
Simultaneous Flash read/write
128 bit Flash buffer and pre-fetch
1MSPS ADC14
8 channel DMA
NVIC with Tail-chaining
Peripheral and SRAM memory bit-band
Since performance is a key goal of MSP432 it was important that we selected the highest performance M device. Cortex -M4F includes access to the full ARM instruction set as well as the DSP extensions and a floating point engine. At the same time, it was important that we incorporate high performance peripherals and features into the device. For example, we included the driver library in ROM. You can access ROM faster than you would if driver library was in flash. Also, the flash is too independent banks which allow you to simultaneously read and write, which takes time. The analog is our fastest yet, 1MSPS 14-Bit ADC, this allows you to sample data faster.

5. ARM Cortex M4F Advantages
Cortex M3 vs. Cortex M4 (SIMD + FPU) DSP Library Benchmark:
Fixed-point ~ 2x-4x faster
Floating-point ~ 10x faster
Source: ARM CMSIS Partner Meeting Embedded World, Reinhard Keil
Utilize the full ARM instruction set with M4F
To elaborate on the Cortex M4F ARM instruction set, you'll see that Cortex M4F includes a full ARM instruction set, compared to M4 or M3 or M0+. This allows you to perform your operations more efficiently. You will also see that Cortex M4F process fixed point operations twice as fast as an M3 and over ten times faster per floating point operations than an M3.

When it comes to low power operation. First we wanted to optimize the silicon for low power. We included capabilities like a wide voltage range. MSP432 can run 1.62V; this includes the full speed as well as flash access. We also integrated the DC/DC that allows you to be more efficient while operating at speeds over 24 MHz The flash buffer NTMA helps you to minimize the CPU cycles. At the same time as having low power silicon, we wanted to provide low power tools and software. The driver library in ROM also consumes less power than if driver library were running out of flash. Tools like ULP Advisor and Energy Trace+ allow you to optimize your code so that you are not consuming extra power where it's unneeded.

8. MSP = ULP
EEMBC’s ULPBench provides a true comparison of microcontroller current consumption and efficiency

See for yourself at
EEMBC the maker core mark has created a new benchmark called the ULPBench, designed to measure Ultra low power across different microcontrollers. You can see here that MSP430 truly has the bench ULPBench score, which shows that our power operation is the most efficient. Here the higher the number the lower the power.

9. EnergyTrace+TM technology
Provides a complete ecosystem for real-time power debugging and quickens time to market. Spends less time debugging and more time developing.
Graphical User Interface in TI’s Code Composer Studio integrated development environment (IDE) and IAR Systems’ Embedded provides energy profiles of your application

All the items in Red that have moved down to MSP432 are the same as the MSP430. You'll notice that the only thing that didn’t port is the core that is because we have the 32-bit ARM Cortex -M4F. Now there are some components that are new to MSP432. New 432 modules and ARM modules which will come with new software. You can program using program using register level style software or use driver library. ARM users have the opportunity to take advantage of CMSIS style coding and we have new IDEs available like **
