What is the M1 series?

In preparation for the introduction of autonomous driving technology, there may be people who are proceeding with the development of new HMIs (Human Machine Interfaces) and the interior parts of the car cockpit. Accompanying the computerization and computerization of automobiles, many safety standards and various security functions against information leakage are required in order to realize autonomous driving technology.

As a new product of the capacitive controller IC "maXTouch" series that realizes multi-point touch, Micrcohip has

 

The new maXTouch "M1Series"is now on sale, targeting automobiles of the new era.

 

At Microhip, we can propose a total package of support up to market introduction, such as introduction of debug tools and various manufacturers, rather than single ICs.

Features of the M1 series

The "M1 series" is a product with many new functions compared to the conventional maXTouch series.

(Please refer to this page for the general maXTouch series overview)

・ The aspect ratio of the number of sensors used for touch sensorscan be changed without changing thefirmware.

(A single chip can handle square to wide sensors.)

・Compliant with automobile safety standard "ISO26262ASIL-B"

・Communication interface:Equipped with two each of I2C (maximum 3.4MHz)and SPI(8MHz)

・Can be used for curved or curved type “LCD”or “OLED” displays

・Compatible with sensors with irregular front panel thicknesses

A single chip can handle 1:1 square, general 16:9, and 5:1 horizontal displays without changing firmware.
