CYUSB3012-BZXC

Application Specific Microcontrollers Overview

The CYUSB3012-BZXC is a SuperSpeed USB peripheral controller from the EZ-USB FX3 family, manufactured by Infineon Technologies. It integrates an ARM926EJ-S core operating at 200 MHz with 256 KB of embedded SRAM. The device supports USB 3.1 Gen 1 and USB 2.0 protocols, featuring a 5-Gbps SuperSpeed PHY and High-Speed On-The-Go (HS-OTG) capabilities. It includes a programmable GPIF II interface for external connectivity and standard peripherals such as SPI, UART, I2C, and I2S. The component utilizes a 121-ball BGA package with dimensions of 10 mm x 10 mm and operates within a commercial temperature range.

Application Specific Microcontrollers Feature Summary

• Supports USB 3.1 Gen 1 (5 Gbps) and USB 2.0 High-Speed OTG protocols
• Features a programmable 100-MHz GPIF II interface with up to 32-bit data bus width
• Includes independent power domains: 1.2 V for core and 1.8–3.3 V for I/O

Application Specific Microcontrollers Applications

• Digital video camcorders and high-definition camera interfaces
• Industrial robot system solutions and digital I/O modules
• Data acquisition systems and data loggers
• Home entertainment applications requiring high-speed data transfer

Application Specific Microcontrollers Procurement Notes

Verify the specific suffix 'BZXC' against the manufacturer's official datasheet to confirm it corresponds to the 256 KB SRAM variant rather than the 512 KB version found in other FX3 models. Ensure the ordering part number matches the exact package and temperature grade requirements for the target design.

Application Specific Microcontrollers Selection Notes

Select this component when a 256 KB memory footprint is sufficient for firmware storage, offering a potential cost advantage over the 512 KB variants. Confirm that the application requires the specific pinout and electrical characteristics of the 121-ball BGA package. Verify compatibility with the EZ-USB FX3 SDK for firmware development.

Application Specific Microcontrollers Part Context

This part belongs to the EZ-USB FX3 family of USB 3.0 peripheral controllers. It shares the same core architecture and interface capabilities as the CYUSB3014 and CYUSB3015 models, differing primarily in the amount of embedded SRAM (256 KB vs. 512 KB). The FX3 series is designed to simplify the integration of high-speed USB connectivity into existing designs.

Application Specific Microcontrollers Replacement Considerations

The CYUSB3014-BZXC serves as a direct functional substitute if the additional 256 KB of SRAM is acceptable for the application. Both components share identical pinouts, packages, and electrical specifications, allowing for drop-in replacement without hardware modifications.
