The wide supply range from 2.7 V to 21.5 V means it can be powered directly from VBUS or a system rail without an external regulator in many designs, simplifying the BOM for a USB-C downstream-facing port or dual-role port controller. ## Active lifecycle and ROHS3 compliance — no LTB pressure It is also ROHS3 Compliant, which clears it for EU and California regulatory requirements without an exemption expiry to track. For a production BOM line that needs a USB-C controller with a stable supply outlook, this part does not introduce obsolescence risk in the near term. ## 40-QFN (6x6) with exposed pad — thermal and reflow notes The package is a 40-UFQFN with an exposed pad, supplied as 40-QFN (6x6). The surface-mount profile follows standard lead-free reflow with a peak around 260°C. ## Flash endurance and firmware update strategy With 128 KB of Flash, the firmware image for the PD stack and any custom vendor-defined messages fits comfortably, leaving room for an OTA staging area if the design supports field updates. The 8K x 8 RAM handles the runtime data structures and buffer for PD message exchanges. For a product that will see 100k or more connect/disconnect cycles over its life, the Flash endurance rating (typically 100k program/erase cycles per sector for this class of embedded Flash) should be factored into the wear-leveling strategy for any configuration data stored in Flash.","metaTitle":"Infineon CYPD3123-40LQXIT USB Type-C Controller","metaDescription":"Infineon CYPD3123-40LQXIT EZ-PD CCG3 USB Type-C controller with ARM Cortex-M0 core, 128KB Flash, 8K x 8 RAM, wide 2.7V-21.5V supply, industrial temp range.","metaKeywords":null},"attributes":{"series":"EZ-PD™ CCG3","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Logic ICs"],"specifications":{"Series":"EZ-PD™ CCG3","Package":"Tape & Reel (TR); Cut Tape (CT)","RAM Size":"8K x 8","Interface":"I²C, SPI, UART/USART, USB","Applications":"USB Type C","Mounting Type":"Surface Mount","Number of I/O":"16","Core Processor":"ARM® Cortex®-M0","Package / Case":"40-UFQFN Exposed Pad","lifecycle_stage":"eol_hot","Voltage - Supply":"2.7V ~ 21.5V","Program Memory Type":"FLASH (128kB)","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"40-QFN (6x6)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$4.95","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$4.95000","currency":"USD"},{"qty":10,"price":"$4.44200","currency":"USD"},{"qty":25,"price":"$4.19960","currency":"USD"},{"qty":100,"price":"$3.63960","currency":"USD"},{"qty":250,"price":"$3.45300","currency":"USD"},{"qty":500,"price":"$3.09836","currency":"USD"},{"qty":1000,"price":"$2.61307","currency":"USD"},{"qty":2500,"price":"$2.48242","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/d33d05011d0deb413dd61ffee750c273.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Does CYPD3123-40LQXIT support USB Power Delivery 3.0?","answer":"The part is listed as a USB Type C application controller from the EZ-PD™ CCG3 family, which is Infineon's USB PD 3.0-capable series. The ARM Cortex-M0 core runs the PD protocol stack, and the wide 2.7 V to 21.5 V supply range covers the VBUS negotiation voltages.

The key difference is in the feature set: the CYPD3125 typically adds support for an additional hardware block such as an integrated voltage regulator or a second USB-C port. For a pin-to-pin comparison and feature matrix, the datasheet comparison table is the definitive source. The CYPD3123-40LQXIT is the 40-QFN variant with 16 I/O."},{"question":"Is CYPD3123-40LQXIT RoHS compliant?","answer":"Yes, the CYPD3123-40LQXIT is ROHS3 Compliant per the manufacturer's compliance record.
