Product details
Overview
MSP430FR2632IRGET from Texas Instruments is an ultra-low-power mixed-signal microcontroller with integrated CapTIvate™ capacitive touch sensing technology, 8 KB program FRAM, 2 KB RAM, and support for up to 8 self-capacitive or 16 mutual-capacitive electrodes. It operates from 1.8 V to 3.6 V, achieves 126 µA/MHz active current, and delivers <5 µA wake-on-touch power in standby mode - enabling battery-powered HMI applications such as smart locks and remote controls.
For engineers reviewing the MSP430FR2632IRGET datasheet, MSP430FR2632IRGET pinout, MSP430FR2632IRGET application, or MSP430FR2632IRGET equivalent, key selection criteria include its 24-pin VQFN (RGE) package, dedicated CapTIvate timing engine, LPM3.5 RTC capability at 730 nA, and hardware-accelerated noise filtering for IEC-61000-4-2/4-4/4-6 compliance.
Technical Context
The MSP430FR2632IRGET integrates a 16-bit RISC CPU with a programmable 16-MHz DCO+FLL clock system, on-chip 32-kHz REFO and 10-kHz VLO oscillators, and a dedicated 16-bit timer for CapTIvate electrode scanning. Its CapTIvate module supports concurrent self- and mutual-capacitance sensing with automatic tuning, spread-spectrum modulation, and hardware debouncing - all while the CPU remains in LPM3 sleep.
It features two eUSCI_A modules (UART/IrDA/SPI), one eUSCI_B (SPI/I²C), an 8-channel 10-bit ADC with 200 ksps sample rate and internal 1.5-V reference, and FRAM memory with ECC, 10¹⁵ write endurance, and unified program/data storage architecture.

Equivalent & Alternatives
The following parts are listed as comparable options for similar capacitive touch microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MSP430FR2532IRGET | Same 24-pin VQFN package, but only 8 mutual-cap electrodes (vs. 16), 1 KB RAM (vs. 2 KB), no dedicated CapTIvate timer | Lower electrode count and reduced RAM limit use in simpler UIs (e.g., 4-button remotes); lacks hardware acceleration for complex sliders | Select when cost sensitivity outweighs need for advanced touch features or larger application code space |
| MSP430FR2632IYQW | Same core specs and CapTIvate capability, but 24-pin DSBGA (2.29 mm × 2.34 mm) - 40% smaller footprint than RGE VQFN | Enables ultra-compact designs (e.g., wearable controllers), but requires micro-via PCB assembly and has lower thermal dissipation | Select when board area is critical and assembly process supports DSBGA; verify thermal margin under continuous CapTIvate scan |
Compared with MSP430FR2532IRGET, the MSP430FR2632IRGET provides double the mutual-cap electrode count and dedicated timing hardware for smoother slider response; compared with MSP430FR2632IYQW, it trades miniaturization for easier thermal management and standard QFN reflow compatibility.

FAQ
What is the maximum number of capacitive touch electrodes supported by the MSP430FR2632IRGET?
The MSP430FR2632IRGET supports up to 8 self-capacitive or 16 mutual-capacitive electrodes. This is confirmed in the device comparison table and functional description of the MSP430FR263x family. The 16 mutual-cap count enables implementation of high-resolution sliders or multi-button panels within the 24-pin VQFN package constraints, and is distinct from the 24-electrode capability of the larger MSP430FR2633 variant.
Does the MSP430FR2632IRGET include hardware-accelerated CapTIvate functionality?
Yes, the MSP430FR2632IRGET includes a dedicated hardware CapTIvate module with built-in spread-spectrum modulation, automatic electrode tuning, noise filtering, and debouncing - all executed without CPU intervention. This is explicitly stated in the "Features" section and reinforced by the presence of a dedicated 16-bit timer for CapTIvate timing, enabling wake-on-touch operation while the CPU remains in LPM3 sleep.
What is the minimum operating voltage for the MSP430FR2632IRGET?
The MSP430FR2632IRGET operates from 1.8 V to 3.6 V. The 1.8 V minimum is specified in the "Embedded microcontroller" feature list and confirmed in Section 5.3 (Recommended Operating Conditions) of the datasheet. Operation below 1.8 V is restricted by SVS threshold levels and is not guaranteed for full peripheral functionality or CapTIvate operation.
Which development tools are officially supported for the MSP430FR2632IRGET?
Texas Instruments officially supports the MSP-CAPT-FR2633 CapTIvate development kit, CAPTIVATE-PGMR programmer, and MSP-TS430RGE24A target socket board for the MSP430FR2632IRGET. The CapTIvate Design Center GUI enables real-time tuning of touch parameters, and MSP430Ware™ provides ROM-resident CapTIvate software libraries - all validated for this specific part number and its 24-pin VQFN configuration.
Is the MSP430FR2632IRGET pin-compatible with other members of the MSP430FR263x family?
No - the MSP430FR2632IRGET (24-pin VQFN/RGE) is not pin-compatible with 32-pin variants like MSP430FR2633IRHB or MSP430FR2633IDA. Within the 24-pin group, it shares identical pinout with MSP430FR2532IRGET and MSP430FR2632IYQW only in signal assignment; however, the DSBGA (IYQW) package has different mechanical layout and solder-ball mapping, so PCBs are not interchangeable.
