Infineon Technologies EZ-USB™ FX2G3 High-Speed Peripheral Controllers

Infineon Technologies EZ-USB™ FX2G3 High-Speed Peripheral Controllers are USB 2.0 device controllers targeting the established USB 2.0 applications in biometrics, scanners, cameras, video, and imaging markets. Based on the MXS40-LP platform, these controllers feature Cortex®-M4 and M0+ MCUs, 512KB Flash, 128KB SRAM, 128KB ROM, serial communication blocks (SCB), and a crypto engine to support various security features. A high-bandwidth data subsystem in the Infineon EZ-USB FX2G3 enables DMA data transfers from an LVCMOS input to a USB output at up to 480 Mbps, supporting USB high-speed host systems. A 1024KB SRAM is included in the high-bandwidth data subsystem to buffer data.
