ATMXT336T-MAU

Overview

The ATMXT336T-MAU is a maXTouch® touchscreen controller IC manufactured by Microchip Technology. It supports up to 336 nodes for capacitive touch sensing and integrates both I2C and SPI interfaces for system communication. The device operates within a supply voltage range of 3.3V and functions reliably across an industrial temperature range of -40°C to +85°C. Packaged in a 56-XQFN (6x6 mm) format with exposed pad, it is designed for surface-mount assembly. This component serves as the core processing unit for multi-touch applications requiring high node counts and robust signal integrity.

Feature Summary

Supports up to 336 touch nodes for complex multi-touch interfaces
Dual interface capability with I2C and SPI support
Industrial operating temperature range from -40°C to +85°C
Integrated 3.3V power supply operation

Applications

High-node-count capacitive touch panels
Industrial control interfaces requiring wide temperature tolerance
Multi-touch display systems using I2C or SPI buses

Procurement Notes

Verify the specific suffix (e.g., T, MAU) against official Microchip documentation to confirm package type, tape-and-reel specifications, and regional availability. Check current distributor stock levels as lead times may vary. Ensure RoHS compliance status matches project requirements before ordering.

Selection Notes

Select this model when a single controller must handle over 100 touch points. Confirm that the host system supports either I2C or SPI protocols. Verify that the PCB layout accommodates the 56-XQFN footprint. Consider thermal management solutions if operating near the upper limit of the specified temperature range.

Part Context

This part belongs to the maXTouch® family of capacitive touch controllers. It shares architectural similarities with other models like the ATMXT336UD but differs in interface options and packaging. The 'T' suffix typically indicates tape-and-reel packaging for automated assembly.

Replacement Considerations

Direct replacements include other ATMXT336 variants such as ATMXT336UD or ATMXT337TPTPMAUR, provided interface and pinout compatibility are verified. Cross-reference datasheets for electrical parameter differences before substitution.
