CY8CTMG110-32LTXI

Application Specific Microcontrollers Overview

The CY8CTMG110-32LTXI is a TrueTouch multi-touch gesture touchscreen controller in a 32-pin QFN package. It supports single-touch and multi-touch applications with up to 24 X/Y sensor inputs for screens of 4.3 inches or smaller. The device features an M8C processor running at 24 MHz, 8 KB Flash, and 512 bytes SRAM. Operating voltage ranges from 2.7V to 5.25V. Average supply current is 4 mA at an 8 ms report rate and 2 mA at a 16 ms report rate. It includes gesture detection libraries, selectable spread-spectrum clocking for EMI immunity, and I2C communication interfaces.

Application Specific Microcontrollers Procurement Notes

Verify the specific ordering suffix '32LTXI' against the manufacturer's official documentation to confirm package type (QFN) and lead-free status. Ensure compatibility with the required operating voltage range of 2.7V to 5.25V and industrial temperature specifications (-40°C to +85°C). Confirm that the design utilizes the 32-pin QFN footprint as specified in the datasheet.

Application Specific Microcontrollers Selection Notes

Select this component for designs requiring integrated gesture detection alongside standard touch functionality. It is suitable for systems needing up to 24 sensor channels and screen sizes up to 4.3 inches. Consider the power consumption requirements; average current is 4 mA at 8 ms report rates. Ensure the host system supports the necessary I2C interface speeds of 100 kHz or 400 kHz.

Application Specific Microcontrollers Part Context

This part belongs to the Cypress TrueTouch family of capacitive touchscreen controllers. It sits between the single-touch CY8CTST110 and the all-point multi-touch CY8CTMA120 in terms of feature set. Unlike the ST110, it includes gesture detection capabilities, making it distinct within the MG110 series variants.

Application Specific Microcontrollers Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Designers should consult Cypress/Infineon application notes for potential cross-references within the TrueTouch family based on specific sensor count and memory requirements.
