Overview
The ATMXT640UD-CCUR001 is a two-wire capacitive touchscreen controller from the maXTouch series, manufactured by Microchip Technology. It operates within a supply voltage range of 1.71V to 3.47V and 3.14V to 3.47V, with a maximum supply current of 40 mA. The device supports I2C and SPI interfaces for communication. It is housed in an 88-UFBGA package measuring 6x6 mm and is designed for surface mount installation. The component functions reliably across an operating temperature range of -40°C to +85°C.
Feature Summary
- Integrated two-wire capacitive touch sensing technology
- Dual interface support for I2C and SPI protocols
- Compact 88-pin UFBGA (6x6 mm) surface-mount packaging
Applications
- Capacitive touchscreen implementations in portable electronics
- Industrial control panels requiring robust touch input
- Automotive infotainment systems with wide temperature tolerance
Procurement Notes
Verify the specific ordering suffix CCUR001 against the official datasheet to ensure correct packaging and revision status. Confirm that the required interface configuration matches the system design, as the device supports both I2C and SPI. Check moisture sensitivity level (MSL 3) requirements for storage and handling procedures prior to assembly.
Selection Notes
Select this component when a high-node count capacitive touch solution is required with flexible communication options. Ensure the host system can accommodate the 1.71V to 3.47V supply range. Verify that the PCB layout supports the 88-UFBGA footprint and thermal requirements for the specified operating temperature range.
Part Context
This part belongs to the ATMXT640 family of touchscreen controllers. It serves as a specialized integrated circuit for detecting touch inputs on capacitive surfaces. The model number indicates specific packaging and revision details within the broader maXTouch product line.
Replacement Considerations
Consult Microchip documentation for direct pin-to-pin or functional equivalents within the ATMXT640 series. Verify compatibility with existing firmware and hardware interfaces before substituting.
