CYPD1105-35FNXIT

Application Specific Microcontrollers Overview

The CYPD1105-35FNXIT is a USB interface integrated circuit belonging to the EZ-PD CCG1 series, manufactured by Infineon Technologies. It integrates an ARM Cortex-M0 core for firmware execution and supports multiple communication interfaces including I2C, SPI, UART, and USB. The device operates within a supply voltage range of 3.2 V to 5.5 V, with a nominal operating voltage of 3.3 V. It is designed for surface-mount installation in a CSP-35 package and functions reliably across a temperature range of -40°C to +85°C.

Application Specific Microcontrollers Procurement Notes

This component is classified as an End-of-Life (EOL) product by the manufacturer. Availability is restricted to existing stock or secondary market sources, as it is no longer actively produced. Verification of authenticity and condition is critical when sourcing from non-direct distributors due to the discontinued status.

Application Specific Microcontrollers Selection Notes

Designers should consider the CSP-35 package constraints and the specific electrical requirements of the 3.3 V logic domain. The inclusion of an ARM Cortex-M0 core allows for custom firmware but requires development resources compatible with this architecture. Verify that the required interface protocols (I2C, SPI, UART, USB) align with the system design before selection.

Application Specific Microcontrollers Part Context

The CYPD1105-35FNXIT is part of the CYPD1105 series within the EZ-PD CCG1 family. This series represents early generations of USB Type-C and Power Delivery controllers developed by Cypress, now under Infineon Technologies. The CCG1 family established foundational capabilities for USB interface control using embedded microcontroller cores.

Application Specific Microcontrollers Replacement Considerations

As the part is discontinued, direct replacements may not exist within the same form factor. New designs should evaluate modern equivalents such as the EZ-PD CCGx series (e.g., CCG3, CCG5, or CCG7 families) which offer updated features and active manufacturing support.
