Texas Instruments has just launched a successor for its 16-bit MSP430 MCU family with MSP432 MCU series featuring a 32-bit ARM Cortex-M4F core, a DSP, up to 256 KB flash, up to 64 KB SRAM, and according to the company ” delivering a ULPBench score of 167.4 outperforming all other Cortex-M3 and -M4F MCUs on the market”. The new MCU family targets consumer & portable electronics, building & factory automation & control, smart grid & energy, healthcare & fitness, and wearables applications.
- MCU – 32-bit ARM Cortex-M4F up to 48 MHz with FPU and DSP. Delivers 3.4 Coremark/MHz
- Memory – Up to 64 KB RAM; Selectable RAM retention
- Storage – Up to 256 KB Flash; dual bank for simultaneous reading and writing
- Security – 256-bit AES encryption, JTAG access lock, 4 IP Protection regions
- EnergyTrace Technology
- Real-time power measurement and debugging
- Generate application energy profiles including current and CPU state
- Ultra-Low Power Consumption:
- 95 uA/MHz active mode
- 850 nA LPM3 (With RTC)
- Wake-Up From Standby Mode in < 10uS
- ADC – 24-ch 14-bit (13.2 ENOB) differential ADC; up to 1 MSPS; 375 uA at full speed
- Voltage – 1.62 to 3.7 V operation
There are currently 6 devices available with 32 to 64KB RAM, 128 to 256KB flash and various I/O options and packages.
To allow customers to quickly evaluate the new MSP432 MCU, Texas Instruments also launched MSP432 LaunchPad Evaluation Kit based on MSP432P401R with 256KB flash and 64KB RAM.
Key features listed for the kit:
- Low-power ARM Cortex-M4F MSP432P401R
- 40-pin LaunchPad standard that leverages the BoosterPack ecosystem
- XDS110-ET, an open-source onboard debugger featuring EnergyTrace+ technology and application UART
- Two buttons and two LEDs for user interaction
- Backchannel UART through USB to PC
The kit includes the board, a micro USB cable, and a quick start guide.
Software examples and hardware design files have been released for the board. Development can be performed with MSPWare Software Development Package either from the desktop or within a web browser. MSP432 MCUs are also said to support real-time operating system (RTOS) such as TI-RTOS, FreeRTOS and Micrium uC/OS.
MSP432P401RIPZ MCU is already sampling, while other upcoming devices will be available later, and pricing starts at $2.15 US in 1K units. MSP-EXP432P401R LaunchPad kit will sell for just $12.99, and the company can also provide MSP-TS432PZ100 target board for $89. You can find more details, including documentation, tools, and software for the boards, on Texas Instruments MSP432 product page.
