CY8CTMG120-56LFXI

Product Overview

CY8CTMG120-56LFXI is a TrueTouch touchscreen controller associated with Cypress Semiconductor / Infineon. The device is cataloged under application-specific microcontrollers because its processing and peripheral resources are optimized for a defined control task rather than general-purpose MCU use.

The parameters below are limited to information located for this exact part or its directly matching base device. Values not reliably exposed in public documentation—especially for customer-programmed TrueTouch, Broadcom and legacy controller variants—are intentionally not inferred from a neighboring suffix.

In design review, CY8CTMG120-56LFXI should be treated as a programmed sensing or control subsystem rather than selected only by CPU speed or package size. Electrode or load topology, analog behavior, noise environment, host protocol, start-up state and firmware configuration can decide whether it works in the original assembly. A footprint-compatible suffix does not prove that calibration data, customer firmware or sensor tuning is transferable. Qualification should include the original configuration archive and functional testing with the production sensor or power stage.

Key Features

• Full part number: CY8CTMG120-56LFXI
• Manufacturer / historical brand: Cypress Semiconductor / Infineon
• Device type: TrueTouch touchscreen controller
• Cypress TrueTouch capacitive-touch controller
• Dedicated touchscreen acquisition and signal-processing firmware
• Host protocol, sensor-node count, display size and gesture support are exact-device or customer-program attributes
• Package/customer option suffix must be retained during repair
• Production validation should use the original sensor stack, cover lens and firmware configuration
• Multi-touch gesture controller family and M8C-based programmable control
• Ordering code indicates a leadless package option; PCB land pattern must follow the exact package drawing
• Industrial-temperature ordering grade is indicated on the researched family; confirm the complete suffix in the official ordering table

Applications

• Capacitive touchscreens and touch-enabled human-machine interfaces
• Portable, consumer and industrial display controls
• Legacy TrueTouch controller repair where firmware and sensor stack are preserved

Application suitability should be confirmed against the original system requirements, including interface role, firmware revision, environmental range, package assembly process and any programmed or calibrated data. These examples describe realistic uses of the researched device family; they do not imply that every ordering suffix includes every optional peripheral or qualification grade.

Quality & Sourcing

Antrex Electronics can support sourcing review for CY8CTMG120-56LFXI, including verification of the complete ordering suffix, package, date code, packaging form and visible marking. Buyers should state the required quantity and whether blank, factory-programmed or customer-programmed material is acceptable. For programmable, secure or touch-controller devices, the firmware image, security provisioning state and customer option code can be as important as the silicon itself; Antrex Electronics does not assume that blank stock will reproduce an installed part. For obsolete or long-stored material, photos, label review, traceability checks, lead or ball inspection, solderability assessment and third-party electrical or X-ray testing can be arranged when project risk warrants them. Availability, date code and test scope remain subject to quotation and inspection.
