4. Challenges Using TI CC2541+MSP430
1. Two chip solution for Radio + Touch
TI’s solution is a two chip solution, thereby increasing board space and BOM cost
2. Manual system tuning for capacitive sensors
TI’s solution requires manual system tuning for every system, manufacturing or environmental change
Involves additional programming efforts and increased costs
3. High level of noise immunity
Interference in 2.4 GHZ spectrum is common and superior noise immunity is required
Noise is also present due to various EMI noise sources such ad RF and AC line noise
TI’s solution lacks any sort of proprietary protocol to eliminate noise
Have you faced any other challenge ?

5. The Solution You Need A one-chip solution that
Saves board space while reducing BOM costs
Eliminates manual system tuning for capacitive sensing
Has superior noise immunity
PRoC-UI solution is the solution you need
One-chip solution for radio, MCU and touch leading to more board space savings and lower BOM cost
SmartSense™ Auto-tuning eliminates manual system tuning by continuously compensating for system, manufacturing and environmental changes
SmartSense_EMC™ is specifically designed for superior noise immunity against external radiated and conducted noise
PRoC-UI creates a one-chip solution for wireless touch HID applications
