Product details
Overview
MSP430TCH5EPWR from Texas Instruments is a haptics-enabled, ultra-low-power 16-bit RISC microcontroller integrating Immersion TouchSense™ technology, a 10-bit 200-ksps ADC with internal reference, and up to 24 capacitive touch I/O pins - designed for touch-and-haptic feedback systems in portable navigation devices and mobile phones.
For engineers reviewing the MSP430TCH5EPWR datasheet, MSP430TCH5EPWR pinout, MSP430TCH5EPWR application, or MSP430TCH5EPWR equivalent, this device delivers programmable audio-to-haptics conversion, LIN-capable UART with automatic baud rate detection, and dual USCI modules supporting SPI, I²C, and IrDA - all within a 28-pin TSSOP package operating from 1.8 V to 3.6 V.
Technical Context
The MSP430TCH5EPWR implements a digitally controlled oscillator (DCO) calibrated to 1–16 MHz with sub-1 µs wake-up from standby mode, paired with five software-selectable low-power modes including LPM4 (0.1 µA RAM retention). Its clock system sources ACLK from either an internal LF oscillator or external 32-kHz crystal.
It integrates two 16-bit Timer_A modules (each with three capture/compare registers), a versatile analog comparator (COMP_A+ with eight channels), and a universal serial communication interface (USCI) with independent UART/LIN/IrDA, SPI, and I²C capability - enabling simultaneous haptics control, capacitive touch sensing, and host communication.

Equivalent & Alternatives
The following parts are listed as comparable options for similar haptics and capacitive touch controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MSP430FR2633IPW | Ferroelectric RAM (FRAM) instead of flash; higher ADC resolution (12-bit); no Immersion license preloaded | Requires external haptics firmware integration; better suited for high-write-cycle sensor fusion applications | Select when long-term data logging or frequent firmware updates are required - not drop-in for TouchSense-based designs |
| DRV2605LRTVT | Dedicated haptics driver IC with closed-loop LRA control; no MCU, no touch sensing, no ADC | Must be paired with external MCU for touch processing and effect sequencing | Select when haptics performance (e.g., fast start/stop, precise amplitude control) is prioritized over integration and BOM count reduction |
Compared with MSP430TCH5EPWR, the MSP430FR2633IPW offers FRAM endurance but lacks factory-licensed TouchSense firmware, while DRV2605LRTVT delivers superior haptics fidelity but requires full external system integration - making MSP430TCH5EPWR optimal for cost-sensitive, integrated touch+haptics endpoints.

FAQ
What haptic actuator types does the MSP430TCH5EPWR support?
The MSP430TCH5EPWR supports both linear resonant actuators (LRA) and eccentric rotating mass (ERM) motors through its integrated PWM and driver interface logic. It includes built-in waveform shaping and closed-loop LRA drive capability via Immersion TouchSense™ firmware, enabling precise frequency and amplitude control without external driver ICs. The MSP430TCH5EPWR datasheet confirms compatibility with common LRA and ERM models used in mobile and portable devices.
Does the MSP430TCH5EPWR include factory-programmed haptics firmware?
Yes, the MSP430TCH5EPWR ships with Immersion TouchSense™ haptics firmware preloaded in flash memory, including 122 licensed haptic effects, audio-to-haptics conversion routines, and programmable sequencing logic. No additional licensing fees or runtime royalties apply. This firmware is integral to the MSP430TCH5EPWR device functionality and cannot be removed or disabled.
Can the MSP430TCH5EPWR operate without an external crystal?
Yes, the MSP430TCH5EPWR can operate using its internal digitally controlled oscillator (DCO) calibrated to frequencies from 1 MHz to 16 MHz, eliminating the need for an external crystal in many applications. The internal very-low-power LF oscillator also provides ACLK for real-time clock functions. An external 32-kHz crystal is optional and only required for high-accuracy timing or specific low-power mode configurations.
How many capacitive touch channels can the MSP430TCH5EPWR support?
The MSP430TCH5EPWR supports up to 24 capacitive touch I/O pins, configurable as self-capacitance or mutual-capacitance inputs. Each pin includes dedicated oscillator enable logic, allowing direct connection to touch electrodes without external components. This capability is confirmed in the device's functional block diagram and Table 1 of the MSP430TCH5EPWR datasheet.
What debug interface does the MSP430TCH5EPWR use?
The MSP430TCH5EPWR uses the Spy-Bi-Wire (SBW) interface for on-chip emulation and programming, accessible via pins RST/NMI/SBWTDIO (pin 24) and TEST/SBWTCK (pin 25). This 2-wire interface replaces traditional JTAG and is fully supported by TI's MSP-FET and Code Composer Studio tools. SBW enables full-speed debugging, flash programming, and real-time register inspection on the MSP430TCH5EPWR.
