Product details
Overview
MSP430TCH5ERHBR from Texas Instruments is a haptics-enabled mixed-signal microcontroller integrating Immersion TouchSense™ technology, a 10-bit 200-ksps ADC, two 16-bit Timer_A modules, and up to 24 capacitive touch I/O pins. It operates from 1.8 V to 3.6 V, supports audio-to-haptics conversion, and targets touch-enabled portable devices requiring tactile feedback with low-power operation.
For engineers reviewing the MSP430TCH5ERHBR datasheet, MSP430TCH5ERHBR pinout, MSP430TCH5ERHBR application, or MSP430TCH5ERHBR equivalent, key selection criteria include its integrated haptics engine, capacitive touch I/O count, 32-pin QFN (RHB) package, ultra-low-power standby current (0.5 µA), and support for LRA/ERM actuator drive via programmable waveform generation.
Technical Context
The MSP430TCH5ERHBR implements a 16-bit RISC CPU with 62.5-ns instruction cycle time, five software-selectable low-power modes, and a digitally controlled oscillator (DCO) enabling wake-up from standby in under 1 µs. Its haptics subsystem is authenticated to run Immersion TouchSense firmware and supports 122 preloaded effects, multiple-effect sequencing, and audio-synchronized playout.
Capacitive touch sensing is implemented across up to 24 GPIO pins with pin-oscillator enable bits, while analog functions include an on-chip comparator (COMP_A+) with eight input channels and internal reference support. Communication is handled by USCI_A0 (UART/LIN/IrDA/SPI) and USCI_B0 (SPI/I²C), both supporting master/slave configurations.

Equivalent & Alternatives
The following parts are listed as comparable options for similar haptics-enabled microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MSP430FR2633IRHBT | FRAM-based (2 KB), lower active current (120 µA), no Immersion license; uses CapTIvate™ instead of TouchSense | Targeted at cost-sensitive consumer devices where haptic licensing cost must be avoided | Select when FRAM endurance and lower power outweigh need for pre-certified haptic effects |
| STM32L053R8T6 | ARM Cortex-M0+, 64 KB flash, no integrated haptics engine; requires external haptics library and driver IC | Suitable for designs needing higher processing throughput and connectivity peripherals (USB, AES) | Select when application demands >16-bit compute capability and ecosystem support over turnkey haptics integration |
Compared with MSP430TCH5ERHBR, MSP430FR2633IRHBT offers superior write endurance and lower active power but lacks factory-licensed TouchSense effects, while STM32L053R8T6 provides broader MCU features at the cost of added software development effort and external component dependency for haptics functionality.

FAQ
What haptic actuator types does the MSP430TCH5ERHBR support?
The MSP430TCH5ERHBR supports both Linear Resonant Actuators (LRA) and Eccentric Rotating Mass (ERM) actuators through its integrated haptics engine and programmable waveform generator. It delivers drive signals via PWM output and supports closed-loop LRA frequency tracking using the on-chip comparator. The device is validated for use with common off-the-shelf LRA and ERM modules without requiring external driver ICs when paired with DRV2603.
Does the MSP430TCH5ERHBR require external programming hardware?
No, the MSP430TCH5ERHBR supports serial onboard programming via its built-in UART bootloader (BSL) using only P1.1 (TX) and P1.5 (RX) pins - no external programming voltage or JTAG adapter is needed. For full-featured debug, Spy-Bi-Wire interface is available through RST/NMI/SBWTDIO and TEST/SBWTCK pins, compatible with TI's MSP-FET toolset.
How many capacitive touch channels can the MSP430TCH5ERHBR handle simultaneously?
The MSP430TCH5ERHBR supports up to 24 capacitive touch I/O pins, all configurable with individual pin-oscillator enable bits for self-capacitance measurement. These pins are distributed across Ports P1, P2, and P3, and can be scanned in autoscan mode by the 10-bit ADC. The device does not require external RC networks or dedicated touch controller ICs to implement buttons, sliders, or wheels.
Is the Immersion TouchSense license included with the MSP430TCH5ERHBR?
Yes, the MSP430TCH5ERHBR ships with a factory-programmed, non-transferable Immersion TouchSense license embedded in its flash memory. This enables immediate use of all 122 certified haptic effects, audio-to-haptics conversion, and programmable sequencing without royalty payments or separate license procurement. The license is authenticated at boot and cannot be reprogrammed or moved to another device.
What is the minimum supply voltage for reliable operation of the MSP430TCH5ERHBR?
The MSP430TCH5ERHBR operates reliably from 1.8 V to 3.6 V. At 1.8 V, it maintains full functionality including ADC operation (200 ksps), haptics engine execution, and capacitive touch sensing - verified across temperature range –40°C to 85°C. Brownout detection activates below 1.7 V to prevent undefined behavior, ensuring safe reset before voltage collapse.
