CYPD1120-35FNXIT

Application Specific Microcontrollers Overview

The CYPD1120-35FNXIT is a USB Power Delivery Alternate Mode Controller from the CCG1 family, designed for Type-C applications. It features a 48-MHz ARM Cortex-M0 CPU with 32-KB flash and 4-KB SRAM. The device integrates an analog block including a 12-bit, 1-Msps ADC for VBUS monitoring and digital peripherals such as two 16-bit TCPWM blocks and one I2C interface. It supports VESA DisplayPort Alternate Mode on USB Type-C Standard Version 1.0. Operating voltage ranges from 1.8 V to 5.5 V, with sleep current of 1.3 mA and deep sleep current of 1.3 µA. The component is housed in a 35-ball wafer-level CSP package.

Application Specific Microcontrollers Procurement Notes

Verify package type compatibility during sourcing, as this specific part number corresponds to the 35-ball WLCSP variant. Confirm that firmware libraries align with the CCG1 architecture requirements. Ensure supply chain continuity checks are performed due to corporate acquisitions affecting product portfolios.

Application Specific Microcontrollers Selection Notes

Select this controller when DisplayPort Alternate Mode support is required alongside USB PD capabilities. The 35-ball WLCSP package is suitable for space-constrained designs compared to the 40-pin QFN alternative. Consider the integrated ADC for simplified VBUS monitoring circuits without external components.

Application Specific Microcontrollers Part Context

This component belongs to the Cypress CCG1 product family, which provides scalable Type-C and USB PD solutions. The CCG1 architecture allows scaling from base Type-C implementations to full 100-W PD solutions with mux support. It functions as a CC controller detecting connector insertion and orientation while managing external power and mux controls.

Application Specific Microcontrollers Replacement Considerations

The CYPD1120-40LQXI serves as a pin-compatible alternative utilizing a 40-pin QFN package instead of the 35-ball WLCSP. Both variants share identical functional specifications and firmware compatibility within the CCG1 family.
