It acts as a bridge between a host USB 3.0 port and a variety of peripheral interfaces — I²C, I²S, SPI, UART, and MMC/SD — so a design can stream video, audio, or bulk data through a single USB connection without an external host processor. A 512K x 8 internal RAM buffer stages the data path; the 59 general-purpose I/O lines let you connect parallel sensors, control lines, or memory-mapped peripherals. Program memory is external — the part executes firmware from a serial SPI Flash or parallel NOR — so the firmware image size is limited only by the external memory you attach. Packaged in a 121-ball TFBGA (10x10 mm body), it is a surface-mount device intended for controlled reflow assembly. The commercial temperature range (0°C to 70°C) fits indoor equipment, test gear, and consumer electronics — not extended-temperature or under-hood environments. ## ARM9 core and external program memory — what it means for firmware The ARM9 core runs the USB protocol stack and application logic. Because program memory is external, the firmware image size is decoupled from the chip — you can store a full USB class driver stack plus application code in a serial Flash. That also means the boot path and memory map must be configured at board design time; the EZ-USB FX3 reference design uses a SPI Flash for the firmware image, which the part loads at power-up. ## Interface set and I/O — what connects without a bridge The I²C bus can talk to codecs, sensors, or EEPROMs; I²S carries digital audio directly; MMC/SD connects to removable storage; SPI handles Flash or ADCs; UART talks to legacy serial devices. The 59 I/O lines are shared among these peripherals and general-purpose signalling — the pin-multiplexing scheme is detailed in the FX3 datasheet and must be reconciled with the external memory interface pins. ## Supply rail and power sequencing Core supply is 1.15 V to 1.25 V, a tight rail that requires a regulated supply. ## Lifecycle and sourcing The CYUSB2014-BZXC carries an Active product status and a current lifecycle stage, so there is no last-time-buy risk and no end-of-life pressure. It remains qualified for new designs and ongoing production.","metaTitle":"Infineon CYUSB2014-BZXC EZ-USB FX3 USB Peripheral Controller","metaDescription":"Infineon CYUSB2014-BZXC EZ-USB FX3 SuperSpeed USB peripheral controller with ARM9 core, 512K x 8 RAM, 59 I/O, 121-FBGA.","metaKeywords":null},"attributes":{"series":"EZ-USB FX3™","packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Series":"EZ-USB FX3™","Package":"Bulk","RAM Size":"512K x 8","Interface":"I²C, I²S, MMC/SD, SPI, UART, USB","Applications":"SuperSpeed USB Peripheral Controller","Mounting Type":"Surface Mount","Number of I/O":"59","Core Processor":"ARM9®","Package / Case":"121-TFBGA","lifecycle_stage":"eol_hot","Voltage - Supply":"1.15V ~ 1.25V","Controller Series":"CYUSB","Program Memory Type":"External Program Memory","Operating Temperature":"0°C ~ 70°C","Supplier Device Package":"121-FBGA (10x10)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$21.05","stockQuantity":0,"priceTiers":[{"qty":20,"price":"$15.60000","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/2cd6223ad4e9755c37f3b73166ff8e91.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Does CYUSB2014-BZXC have a built-in ARM9 core?","answer":"Yes, the core processor is an ARM9, running the SuperSpeed USB protocol stack and application firmware."},{"question":"What is the difference between CYUSB2014 and CYUSB3014?","answer":"Both are EZ-USB FX3 devices with the same ARM9 core and 512K x 8 RAM.
