Overview

The MSP430FR2512IRHLR is a 16-bit ultra-low-power microcontroller featuring TI CapTIvate technology and 7.5KB of unified Ferroelectric RAM (FRAM). It is specifically optimized for high-performance capacitive touch sensing applications, supporting up to 8 self-capacitance or 16 mutual-capacitance sensors. The integration of CapTIvate allows for touch functionality with high noise immunity and reliable operation even in the presence of water.

Why Choose This Part

The inclusion of FRAM provides 10^15 write cycle endurance and non-volatile storage with much lower power requirements than traditional Flash. CapTIvate technology offers dedicated hardware for capacitive sensing that operates autonomously in low-power modes, significantly reducing CPU overhead. The device also features a 10-bit ADC and multiple clock sources, including an on-chip 16MHz DCO with FLL for stable timing without external crystals.

Applications

Water-Resistant Touch Interfaces
Utilizes CapTIvate technology to maintain reliable touch detection on surfaces exposed to water or moisture, such as kitchen appliances or outdoor control panels.
Proximity Sensing
Enables gesture control and human-presence detection through sensitive proximity channels that wake the system from low-power modes.
Battery-Powered Consumer Devices
Ideal for handheld electronics requiring high write-cycle endurance for data logging via FRAM and ultra-low standby current for long battery life.
Industrial Keypads
Supports robust multi-touch functionality and advanced debouncing for physical control interfaces in electrically noisy industrial environments.
