The USB interface is the Type-C physical layer itself — the controller handles CC (Configuration Channel) detection, VBUS negotiation, and BMC (Biphase Mark Coding) encoding for PD messaging. On a motherboard, the I2C lines connect to an embedded controller or EC; in a standalone power adapter, the SPI port talks to a secondary MCU or flash for firmware storage. The 20 GPIOs can be mapped to LED indicators, load switches, or current-sense inputs. ## Lifecycle: active production, no LTB risk No last-time-buy or end-of-life notice applies. The part is RoHS3 compliant. For new designs, this means no forced redesign cycle from obsolescence; for production runs, the supply channel is stable through independent distribution. ## Package and marking — what to check on receipt The exposed pad must be soldered to a thermal land on the PCB for heat dissipation — the datasheet's recommended footprint shows the pad connection to ground. On incoming inspection, verify the laser-etched top mark matches Infineon's standard for the EZ-PD family: the date-code font and logo placement should be consistent across the reel or tray. Any variation in font, missing corner chamfer, or re-sanded surface is a red flag for gray-market re-marking.","metaTitle":"CYPD3135-40LQXI EZ-PD CCG3 USB-C Controller, ARM Cortex-M0","metaDescription":"Infineon CYPD3135-40LQXI USB Type-C controller, ARM Cortex-M0, 128KB Flash, 8K x 8 RAM, I2C/SPI/UART/USB, -40 to 85°C, 40-QFN.
