CY8CTMA120-56LFXA

Application Specific Microcontrollers Overview

The CY8CTMA120-56LFXA is a TrueTouch single-touch touchscreen controller manufactured by Cypress Semiconductor. It is designed for capacitive touch sensing applications, integrating the necessary analog and digital logic to detect touch events on a display panel. The device operates within a supply voltage range of 1.71V to 5.5V and is housed in a 56-lead Quad Flat Package No-lead (QFN) with dimensions of 8mm x 8mm. It supports standard communication interfaces for system integration.

• Compact 56-QFN (8x8 mm) package

Application Specific Microcontrollers Applications

• Mobile phone touchscreens
• Personal Digital Assistants (PDAs)
• Portable media players

Application Specific Microcontrollers Part Context

This component belongs to the Cypress TrueTouch family of capacitive touch controllers. It is part of a broader series that includes variants such as the CY8CTST110 and CY8CTST120, which share similar functional architectures but differ in pin counts and package types. The CY8CTMA120 specifically targets single-touch applications requiring a balance of performance and form factor.

Application Specific Microcontrollers Replacement Considerations

Direct replacements include other members of the TrueTouch single-touch family, such as the CY8CTST110 or CY8CTST120, depending on the required package type (SSOP, QFN, or TQFP). Verification of pin compatibility and firmware configuration is required when substituting between different package variants within the same functional family.
