The West Bridge Antioch device (CYWB0124AB) is a peripheral controller supporting High-Speed USB and Mass Storage access. This controller provides access from a processor interface and a High-Speed USB (HS-USB) interface to peripherals including SD, MMC/MMC+, and NAND. It supports interleaving accesses between the processor interface, the HS-USB, and the peripherals so that an external processor and an external USB Host can transfer data to each other and to the mass storage peripherals simultaneously.
