That saves a DC-DC stage and its associated inductor and caps. The -40°C to 105°C operating range covers industrial environments — motor-drive cabinets, outdoor telecom enclosures, factory-floor HMI panels — where the ambient around the controller can run hot. If your design lives in a climate-controlled office, you have margin to spare. ## Memory split: Flash, ROM, and RAM The 128 KB Flash holds the PD stack and application code; the 32 KB ROM typically carries a bootloader or fixed-function PD firmware, freeing Flash space for custom logic. The 16K x 8 RAM gives you enough buffer for PD message handling and data transfers. For designs that need more data memory, the Cortex-M0 can page external EEPROM over I2C, but the onboard RAM covers most USB PD sink and source scenarios. ## Lifecycle and sourcing The CYPM1115-48LQXI carries an Active lifecycle status from Infineon. No last-time-buy or end-of-life notice is in effect.","metaTitle":"Infineon CYPM1115-48LQXI EZ-PD USB-C Controller","metaDescription":"Infineon CYPM1115-48LQXI EZ-PD PMG1-B1 USB Type-C controller with ARM Cortex-M0, 128KB Flash, 4V-24V supply, -40 to 105°C.

The XI variant ships in a Tray; the XT variant ships in Tape & Reel. Electrically and functionally they are the same device. Choose the packing form that matches your pick-and-place line or your preferred reel quantity."},{"question":"Is CYPM1115-48LQXI compatible with USB PD 3.0?","answer":"The EZ-PD PMG1- family is designed for USB Type-C applications and supports the USB PD specification. The exact PD revision level should be confirmed in the Infineon firmware release notes, but the hardware is built for the PD 3.0 feature set including extended power range and fast role swap."},{"question":"What is the closest functional alternative to CYPM1115-48LQXI?","answer":"The CYPD2122-24LQXIT is another Infineon EZ-PD USB-C controller with an ARM Cortex-M0 core, but it carries 32 KB Flash versus 128 KB, has 14 I/O versus 21, and is rated for -40°C to 85°C versus -40°C to 105°C. It is not a pin-compatible drop-in, but for a less memory- or temperature-demanding USB PD sink design it could be a functional alternative. Verify firmware porting effort and pin mapping before substituting."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/infineon/CYPM1115-48LQXI","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/infineon/CYPM1115-48LQXI when reusing this data.
