Application Specific Microcontrollers datasheet and documents for CY8CTMA340-48LQI-03
Application Specific Microcontrollers Overview
The CY8CTMA340-48LQI-03 is a TrueTouch multi-touch touchscreen controller manufactured by Infineon Technologies (formerly Cypress Semiconductor). It operates on an ARM Cortex-M0 core and supports up to two independent fingers with passive stylus replacement capabilities. The device features a 48-pin QFN package, I2C and SPI interfaces, and handles sensors up to 4.5 inches diagonal with 252 intersections. Power requirements include a digital supply of 1.71 V to 3.6 V and an analog supply of 2.7 V to 3.6 V.
Application Specific Microcontrollers Feature Summary
- Supports up to two fingers and passive stylus tracking
- Integrated Charger Armor technology for noise immunity
- Water rejection and large object detection
- Self-calibrating environmental adaptation
Application Specific Microcontrollers Applications
- Smartphones and mobile devices
- Tablets and portable electronics
- Industrial touch panels requiring water resistance
Application Specific Microcontrollers Procurement Notes
Verify the ordering suffix '03' confirms the specific feature set including two-finger support and stylus capability. Confirm the package type matches the 48-pin QFN requirement. Check RoHS compliance status in the latest datasheet revision before procurement.
Application Specific Microcontrollers Selection Notes
Select this model when two-finger interaction and stylus input are required. Ensure the application supports the 4.5-inch maximum screen size limit. Verify that the host system can provide the necessary 1.71 V to 3.6 V digital and 2.7 V to 3.6 V analog power rails.
Application Specific Microcontrollers Part Context
This component belongs to the CY8CTMA340 family of TrueTouch controllers. It shares the same hardware platform as other variants but differs in firmware-defined feature sets such as finger count and stylus support. The '48LQI' designation specifies the 48-pin QFN package option.
Application Specific Microcontrollers Replacement Considerations
Direct replacements within the same family include CY8CTMA340-48LQI-01T (two fingers, no stylus) or CY8CTMA340-48LQI-09T (four fingers, no stylus). Firmware configuration must be updated to match the new part's capabilities.
