MTCH1030T-I/ST

Overview

The MTCH1030T-I/ST is a capacitive touch controller from Microchip Technology, designed for robust water-tolerant touch detection and proximity sensing. It supports up to three capacitive sensors with Driven Shield+ capability. The device operates on a supply voltage of 2V to 5.5V and functions within an industrial temperature range of -40°C to +85°C. It utilizes GPIO configuration via dedicated pins (CFG0, CFG1, CFG2) to adjust measurement period, oversampling, and sensitivity at runtime. The component is housed in a 14-TSSOP package.

Feature Summary

• Capacitive touch sensing with Driven Shield+ technology for high signal-to-noise ratio
• Water tolerant touch detection suitable for challenging environments
• Easy Tune feature for automatic sensitivity adjustment at runtime
• Multi-stage active noise suppression filters for reliable operation

Applications

• Consumer electronics touch interfaces
• Industrial control panels requiring water tolerance
• Proximity sensing applications through plastic or metal front panels

Procurement Notes

Verify the ordering suffix 'T' indicates tape and reel packaging when sourcing this specific variant. Confirm the '-I' suffix corresponds to the industrial temperature grade (-40°C to +85°C). Ensure compatibility with the 14-TSSOP footprint during PCB layout. Cross-reference the datasheet revision DS40002457A for the most current electrical specifications.

Selection Notes

Select this model for applications requiring up to three independent touch channels without complex firmware integration. The GPIO-based configuration allows for hardware-level tuning of response time and power consumption. Consider the Easy Tune feature if minimizing external components and development time is a priority. Verify that the required sensor size and overlay thickness align with the recommended configurations for optimal performance.

Part Context

The MTCH1030 belongs to the MTCH10xx series of capacitive touch controllers from Microchip Technology. This series includes variants like the MTCH1010 (single channel) and MTCH1060 (six channels), offering scalable solutions for embedded systems. The MTCH1030 specifically targets mid-range applications needing multiple buttons with robust environmental immunity.

Replacement Considerations

The MTCH1030-I/ST is a tube-packaged equivalent of the MTCH1030T-I/ST. Other series members include the MTCH1010 for single-button needs and the MTCH1060 for six-button configurations. Check pinout compatibility if substituting with other MTCH series devices.
