Application Specific Microcontrollers Procurement Notes

This component is classified as End-of-Life (EOL). The manufacturer has announced that production will cease, and the part is scheduled to be discontinued. Buyers should verify current availability through authorized distributors and consider alternative solutions for new designs due to the lack of future supply assurance.

Application Specific Microcontrollers Selection Notes

Designers should evaluate the 32 kB flash and 4 kB RAM limits against application requirements. The 48 MHz processing speed and 12-bit ADC resolution define the performance envelope. Verify that the QFN-40 package footprint matches the PCB layout constraints and that the 3.2 V to 5.5 V supply range aligns with the system power architecture.

Application Specific Microcontrollers Part Context

The CYPD1134-40LQXI is part of the Cypress CCG1 series, now integrated into Infineon's portfolio following the acquisition of Cypress Semiconductor. This specific model represents a single-port USB Type-C controller solution based on the ARM Cortex-M0 architecture, distinct from higher-capacity variants in the CCGx family.

Application Specific Microcontrollers Replacement Considerations

Due to the End-of-Life status, direct functional substitutes are not explicitly listed in public documentation. Engineers must identify pin-compatible or functionally equivalent devices from the CCGx family or other USB Type-C controller lines, ensuring compatibility with existing firmware and hardware interfaces.
