Controllers accelerate USB 2.0 throughput

Infineon’s EZ-USB FX2G3 USB 2.0 peripheral controllers provide DMA data transfers from LVCMOS inputs to USB outputs at speeds of up to 480 Mbps. Designed for USB Hi-Speed host systems, the devices also support Full-Speed (12 Mbps) and Low-Speed (1.5 Mbps) operation.

Built on the company’s MXS40-LP platform, EZ-USB FX2G3 controllers integrate up to six serial communication blocks (SCBs), a crypto accelerator supporting AES, DES, SHA, and RSA algorithms for enhanced security, and a high-bandwidth data subsystem with up to 1024 KB of SRAM for USB data buffering. Additional on-chip memory includes up to 512 KB of flash, 128 KB of SRAM, and 128 KB of ROM.

The family includes four variants, ranging from basic to advanced, all featuring a 100-MHz Arm Cortex-M0+ CPU, while the top-end device adds a 150-MHz Cortex-M4F. The peripheral I/O subsystem accommodates QSPI configurable in single, dual, quad, dual-quad, and octal modes. SCBs can be configured as I2C, UART, or SPI interfaces. The devices provide up to 32 configurable USB endpoints, making them suitable for a wide range of consumer, industrial, and healthcare applications.

EZ-USB FX2G3 controllers are now available in 104-pin, 8×8-mm LGA packages.
