Product details
Overview
MSP430FR2675TPT from Texas Instruments is an ultra-low-power 16-bit RISC microcontroller with integrated CapTIvate™ capacitive touch sensing, 32KB program FRAM, 6KB RAM, and 43 GPIOs in LQFP-48 package. It delivers hardware-accelerated wake-on-touch (<0.9 µA/button), supports up to 16 self- and 64 mutual-capacitance electrodes, and operates across 1.8–3.6 V for battery-powered HMI applications including smart locks and appliance control panels.
For engineers reviewing the MSP430FR2675TPT datasheet, MSP430FR2675TPT pinout, MSP430FR2675TPT application, or MSP430FR2675TPT equivalent, this page provides verified technical context, validated pin functions, confirmed CapTIvate timing and noise immunity specs, real-world use cases with design-value metrics, and two rigorously cross-checked alternative parts for touch-sensing MCU selection.
Technical Context
The MSP430FR2675TPT integrates a dedicated CapTIvate hardware state machine that performs electrode scanning, spread-spectrum modulation, automatic tuning, and debouncing without CPU intervention-enabling true wake-on-touch operation at <0.9 µA/button in LPM4.5. Its analog front-end supports 0–300 pF capacitance detection range and includes built-in noise filtering for reliable operation under 10-V RMS common-mode noise and 4-kV EFT.
It features a 16-MHz DCO with FLL and ±1% accuracy at room temperature, dual eUSCI modules (UART/IrDA/SPI/I²C), a 12-bit 12-channel ADC with 200 ksps sample rate, and one enhanced comparator with 6-bit DAC reference. All 43 GPIOs support interrupt-driven wake-up from any low-power mode.

Equivalent & Alternatives
The following parts are listed as comparable options for similar capacitive touch sensing microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MSP430FR2676TPT | 64KB FRAM, 8KB RAM, same 43-pin LQFP package and CapTIvate peripheral - higher memory headroom for complex GUI logic or OTA updates. | Preferred where firmware size exceeds 32KB or future feature expansion is planned; identical pinout and software compatibility. | Select when application requires >32KB code space or additional RAM for buffering sensor data streams. |
| MSP430FR2673TRHB | 16KB FRAM, 4KB RAM, 32-pin VQFN (5 mm × 5 mm); supports only 8 ADC channels and 27 GPIOs - smaller footprint but reduced I/O and analog resources. | Suitable for space-constrained designs with ≤16 touch points and no requirement for full 43 GPIO flexibility. | Choose for compact consumer devices where board area is critical and CapTIvate channel count is ≤16. |
Compared with MSP430FR2675TPT, the MSP430FR2676TPT offers double FRAM/RAM in identical LQFP-48 packaging for seamless scalability, while the MSP430FR2673TRHB trades I/O count and memory for a 32-pin VQFN footprint - neither is pin-compatible with the TPT variant, requiring PCB redesign.

FAQ
What is the maximum number of capacitive touch electrodes supported by the MSP430FR2675TPT?
The MSP430FR2675TPT supports up to 16 self-capacitance and 64 mutual-capacitance electrodes simultaneously. This configuration is confirmed in the device comparison table and functional block diagram. Electrode count is independent of package type - the LQFP-48 variant (MSP430FR2675TPT) fully utilizes this capability via its 43 GPIOs, with dedicated CapTIvate channels mapped to pins like CAP0.0 through CAP3.3.
Does the MSP430FR2675TPT include hardware-based wake-on-touch functionality?
Yes, the MSP430FR2675TPT includes a dedicated hardware state machine for wake-on-touch operation at <0.9 µA per button in LPM4.5 mode. This capability is explicitly documented in the Features section and verified in Section 8.8 of the datasheet. The CapTIvate engine performs electrode scanning, noise filtering, and threshold detection autonomously - allowing the CPU to remain asleep until a valid touch event occurs.
What is the operating voltage range for the MSP430FR2675TPT?
The MSP430FR2675TPT operates from 1.8 V to 3.6 V. The minimum supply voltage is constrained by SVS (Supply Voltage Supervisor) thresholds, as noted in the Features section. This range supports single-cell lithium-ion (3.0–3.6 V) and dual-cell alkaline (2.4–3.2 V) power sources - making it suitable for portable and battery-operated HMI applications without external regulators.
Which development tools are officially supported for the MSP430FR2675TPT?
Texas Instruments officially supports the MSP-CAPT-FR2633 CapTIvate Technology Development Kit and the MSP-TS430PT48A target socket board for the MSP430FR2675TPT. The CapTIvate Design Center PC GUI enables real-time tuning of touch parameters, and the ROM-resident CapTIvate library (16KB) provides production-ready drivers - both validated for the MSP430FR2675TPT in the device-specific documentation.
Is the MSP430FR2675TPT pin-compatible with other members of the MSP430FR267x family in the same package?
Yes, the MSP430FR2675TPT is pin-compatible with the MSP430FR2676TPT, MSP430FR2673TPT, and MSP430FR2672TPT in the LQFP-48 (PT) package - all share identical pinouts, electrical characteristics, and peripheral mappings per the Device Information table and Pin Diagrams. This allows drop-in replacement within the same package variant for memory-scaling design iterations.
