Frequently Asked Questions
How many independent touch channels does MTCH108-I/SS support, and what electrode configurations are possible?
MTCH108-I/SS supports up to 8 independent capacitive touch inputs, each driven by a separate electrode connected directly to the IC pins. This allows designs to implement up to 8 distinct touch buttons or zones in a single chip without external multiplexers, simplifying PCB routing for 8-button HMI panels.
Does MTCH108-I/SS require an external host microcontroller to decode touch events?
No. MTCH108-I/SS operates in standalone mode, with each touch input producing a direct output signal that can drive LEDs, relays, or logic inputs. This eliminates the need for firmware development and an external MCU in simple 8-button applications, reducing BOM cost and development time by several weeks compared to software-based capacitive solutions.
What are the SMT assembly constraints for MTCH108-I/SS, and is the package compatible with standard reflow profiles?
MTCH108-I/SS uses a 20-pin SSOP package with a matte tin terminal finish and is rated for peak reflow temperatures up to 260°C with a maximum time at peak of 40 seconds. This is fully compatible with standard lead-free SAC305 solder reflow profiles used on most commercial SMT assembly lines.
What is the supply chain outlook for MTCH108-I/SS, and should buyers stock ahead for new product designs?
Microchip lists a YTEOL of 13 years, indicating the part has a long active lifecycle ahead. Factory lead time is approximately 6 weeks, so production planners should buffer 6 to 8 weeks of safety stock. The stable lifecycle projection makes MTCH108-I/SS a low-risk choice for new HMI designs requiring multi-year supply continuity.
