Application Specific Microcontrollers datasheet and documents for CY8CTMG120-00AXI

CY8CTMG120-00AXI

Application Specific Microcontrollers Overview

The CY8CTMG120-00AXI is a capacitive touch sensing microcontroller from Cypress Semiconductor, belonging to the PSoC 3 family. It integrates a CapSense module utilizing the CSA (CapSense with Successive Approximation) method for touch detection. The device features an 8-bit CPU core and programmable analog blocks, designed to implement touch interfaces such as buttons and sliders. This component enables cost-effective capacitive touch solutions by combining sensing logic with processing capabilities in a single chip.

Application Specific Microcontrollers Part Context

This part belongs to the Cypress PSoC 3 series, which combines programmable mixed-signal arrays with a processor core. The CY8CTMG120 variant specifically targets applications needing integrated touch sensing without external controllers. It is part of the broader ecosystem of programmable system-on-chip solutions offered by Cypress (now Infineon).

Application Specific Microcontrollers FAQ

What sensing method does the CY8CTMG120 use?

It uses CapSense with Successive Approximation (CSA), implemented within the Cy8c20x34 PSoC device family architecture.

How is the CapSense system calibrated?

Self-calibration is accomplished through a successive approximation binary search to determine the IDAC setting necessary to keep voltage on Cmod at Vref when no finger is present.
