CY7C63221A-PXC

Product Overview

CY7C63221A-PXC belongs to the Cypress Semiconductor / Infineon application-specific controller portfolio and is identified as a Cypress USB controller or USB microcontroller. It combines programmable or protocol-control logic with peripherals selected for its target system, so replacement decisions must use the complete part number.

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.

Integration of CY7C63221A-PXC depends on more than the advertised protocol. Confirm controller role, USB or network speed, endpoint or channel resources, external-memory requirements, clocking, transceiver connections, firmware-loading method, boot behavior, host drivers and exact pinout. For discontinued controllers, archived firmware and descriptors can be essential. A related family member may require recompilation, PCB changes or driver updates even when its protocol name appears identical.

Key Features

• Full part number: CY7C63221A-PXC
• Manufacturer / historical brand: Cypress Semiconductor / Infineon
• Device type: Cypress USB controller or USB microcontroller
• Application-specific USB controller architecture
• USB role and speed depend on the exact base number
• Package, memory and processor core must be checked against the exact device data sheet
• M8B enCoRe low-speed USB microcontroller
• 3 KB OTP program memory on documented CY7C6322x/6323x variants
• Ordering code identifies a legacy through-hole or package option requiring exact mechanical confirmation

Applications

• USB peripherals, bridges, hubs or host functions matching the exact controller role
• Human-interface and embedded-connectivity products
• Legacy USB platform maintenance

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 CY7C63221A-PXC, 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.
