Overview
The ATMXT2496M1E-ARVAO is a maXTouch touchscreen controller featuring an ARM-based architecture with 100 channels. It supports both mutual and self-capacitance measurements, where self-capacitance augments mutual data for enhanced performance. The device operates within an extended temperature range of -40°C to +85°C. It utilizes I2C or SPI interfaces for communication and includes debug signal capabilities. The component is designed for high-performance touch applications requiring robust connectivity and processing.
Feature Summary
- Supports simultaneous mutual and self-capacitance measurements
- Integrates ARM-based processing for efficient signal handling
- Enables conversion of I2C/SPI and debug signals to USB
- Facilitates direct communication with PC-based applications
Applications
- USB bridge interface for touchscreen controllers
- Debugging and development of maXTouch systems
- PC-based application communication for touch devices
Procurement Notes
Verify the specific suffix ARVAO against official Microchip documentation to confirm package type and tape-and-reel configuration. Ensure compatibility with existing I2C or SPI host interfaces. Confirm that the ARM-based bridge functionality aligns with system requirements for USB conversion and debug signal routing before finalizing procurement.
Selection Notes
Select this component when a dedicated USB bridge solution for maXTouch controllers is required. It is suitable for designs needing ARM-based processing to handle capacitance measurements efficiently. Consider its support for both mutual and self-capacitance if advanced touch sensing is necessary. Verify interface compatibility with the target host system.
Part Context
This part belongs to the maXTouch family from Microchip Technology, specialized for touchscreen control. The M1E variant indicates specific channel counts and feature sets. It serves as an interface board converting serial protocols to USB, aiding in development and debugging processes for embedded touch solutions.
Replacement Considerations
Check for ATMXT2496M1E-AVAO as a potential alternative with similar channel counts but different packaging. Verify functional equivalence regarding ARM architecture and capacitance measurement capabilities before substitution.
