Capacitive touch + host controller? Let TI completely change your HMI!
The new MSP430FR2675 and MSP430FR2676 devices will help expand your designs with capacitive touch while saving time, board space and therefore cost savings. Here is a quick overview of the CapTIvate benefits, specifically for these two new devices:
Ease of use
With a wide range of tools and resources, you can save time and launch products faster - start your design in less than 5 minutes.
Versatility
Provides design flexibility with full configurability, including self-capacitance and mutual-capacitance sensors and a comprehensive library of controls for buttons, sliders, wheels, and proximity sensing.
Minimum power
Touch is automatically detected without CPU intervention, ensuring long battery life.
Robustness and reliability
IEC and IPX certified conducted noise and water resistant solutions to avoid false touch detection and achieve superior reliability.

As shown in Figure 1, the MSP430FR2675 and MSP430FR2676 offer 32KB and 64KB of non-volatile memory, giving you more code space to run application code or store/log data. Higher pin count packages (including 32-pin VQFN, 40-pin LQFP, and 48-pin LQFP) provide enough serial communication ports and GPIOs to connect with other system components. If you want to connect with analog sensors, the integrated 12-bit ADC can meet your needs. Why rely on a two-chip (host microcontroller + discrete capacitive touch microcontroller) solution? Designers can save BOM cost and board space by leveraging the CapTIvate™ capacitive touch sensing microcontroller single-chip solution.
These devices are certified for an extended temperature range up to 105°C – a key requirement for designers in home appliance applications. In addition, Captivate IP automates several noise-resistant post-processing techniques, such as multi-frequency scanning and oversampling, for more robust capacitive touch. With this combination of features, the MSP430FR2675 and MSP430FR2676 can serve as the main system controller in your application!
Portfolio Scalability and Ecosystem

Project requirements may change over time, and you may need the flexibility to add or remove features along the way. If you want your design to be platform-like, you need an MCU family that can meet your requirements.
With the introduction of the MSP430FR2633, along with the MSP430FR2675 and MSP430FR2676, CapTIvate now offers pin-compatible solutions for 16KB, 32KB, and 64KB microcontrollers in 32-pin quad flat no-lead (QFN) packages (see Figure 2), so you don’t have to redesign from scratch as requirements change.
Discover how these new devices can revolutionize your HMI by pushing the limits of capacitive touch and acting as the main system microcontroller.
