CY8CTMA120-00AXI

Application Specific Microcontrollers Overview

The CY8CTMA120-00AXI is a TrueTouch™ Multi-Touch All-Point Touchscreen Controller by Cypress Semiconductor. It supports up to 37 X/Y sensor inputs for screens up to 7.3 inches, tracking up to 10 independent fingers with customizable gestures. The device features an M8C processor running at 24 MHz, 16K Flash, and 1K SRAM. It integrates Full-Speed USB (12 Mbps) without external crystals, I2C interfaces, and configurable analog/digital PSoC blocks. Operating voltage ranges from 3V to 5.25V, with industrial temperature support (-40°C to +85°C).

Application Specific Microcontrollers Feature Summary

• Multi-Touch All-Point Detection: Tracks up to 10 fingers with customizable gesture development.
• High Performance Sensing: Supports up to 37 sensors, typical scan rate of 120 µs per X/Y crossing.
• Integrated USB Interface: Full-Speed USB 2.0 compliant (12 Mbps) with no external crystal required.
• Configurable Architecture: Includes M8C CPU (24 MHz), 16K Flash, 1K SRAM, and programmable analog/digital blocks.

Application Specific Microcontrollers Applications

• Premium mobile phones requiring multi-touch capabilities.
• E-readers and tablets with screen sizes up to 7.3 inches.
• Industrial control panels needing robust capacitive touch input.

Application Specific Microcontrollers Procurement Notes

Verify the specific ordering suffix '-00AXI' against the manufacturer's current datasheet to confirm package type (TQFP-100) and lead-free status. Ensure compatibility with existing firmware libraries, as the M8C architecture requires specific development tools like PSoC Designer.

Application Specific Microcontrollers Selection Notes

Select this component for applications requiring simultaneous multi-finger tracking and custom gesture recognition. Compare against CY8CTMG120 if all-point addressing is not needed but similar sensor counts are required. Verify that the 56-pin QFN or 100-ball VFBGA package options align with PCB layout constraints.

Application Specific Microcontrollers Part Context

The CY8CTMA120 belongs to the TrueTouch MA series, designed for high-end multi-touch applications. It sits above the CT (Capacitive Touch) and MG (Multi-Gesture) series in terms of sensing complexity, offering all-point addressability unlike the gesture-only MG series.

Application Specific Microcontrollers Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Cross-reference with CY8CTMG120 for non-all-point needs or CY8CTST120 for single-touch requirements, subject to firmware adaptation.
