CYPD5126-40LQXI

Product Overview

Designed around a dedicated embedded-control role, CYPD5126-40LQXI is a EZ-PD CCG USB-C Power Delivery controller from the Cypress Semiconductor / Infineon product lineage. Its full ordering code matters because silicon option, memory, package, temperature grade and shipment format may change across closely related suffixes.

The parameters below are limited to information located for this exact part or its directly matching base device. Values not reliably exposed in public documentation—especially for customer-programmed TrueTouch, Broadcom and legacy controller variants—are intentionally not inferred from a neighboring suffix.

Qualification of CYPD5126-40LQXI should compare the complete electrical and functional design: processor architecture, memory model, clock source, reset and start-up behavior, supply rails, interface levels, package pinout, programmed content and supported development tools. For legacy or application-specific silicon, an apparently similar controller may not accept the same firmware or reproduce cycle-level timing. Preserve the original binary, configuration data and board test procedure before approving a replacement.

Key Features

• Full part number: CYPD5126-40LQXI
• Manufacturer / historical brand: Cypress Semiconductor / Infineon
• Device type: EZ-PD CCG USB-C Power Delivery controller
• Programmable USB Type-C configuration-channel and Power Delivery control
• Embedded Arm Cortex-M-class processing on documented EZ-PD CCG generations
• Flash-based policy firmware and configurable host interfaces
• Connector role, port count, alternate modes, power-path control and supported PD revision depend on the exact CYPD base number
• Automotive or commercial qualification, package and reel option are encoded by the full ordering suffix
• CCG5-generation USB-C / Power Delivery controller family
• Ordering code indicates a QFN/LQFN-style surface-mount package family; confirm exact terminal count from the package drawing
• Industrial-temperature ordering grade is indicated on the researched family; confirm the complete suffix in the official ordering table

Applications

• Application-specific embedded control
• Original-platform maintenance and exact-part replacement

Application suitability should be confirmed against the original system requirements, including interface role, firmware revision, environmental range, package assembly process and any programmed or calibrated data. These examples describe realistic uses of the researched device family; they do not imply that every ordering suffix includes every optional peripheral or qualification grade.

Quality & Sourcing

Antrex Electronics can support sourcing review for CYPD5126-40LQXI, including verification of the complete ordering suffix, package, date code, packaging form and visible marking. Buyers should state the required quantity and whether blank, factory-programmed or customer-programmed material is acceptable. For programmable, secure or touch-controller devices, the firmware image, security provisioning state and customer option code can be as important as the silicon itself; Antrex Electronics does not assume that blank stock will reproduce an installed part. For obsolete or long-stored material, photos, label review, traceability checks, lead or ball inspection, solderability assessment and third-party electrical or X-ray testing can be arranged when project risk warrants them. Availability, date code and test scope remain subject to quotation and inspection.
