ALFAT SoC processor concept, pin-out, specifications, commands, hardware integration guide and full information needed to implement a solution using this processor. A high performance FAT file system SoC processor with dual USB Host interfaces and 4-bit SD interface. Controlled through UART, SPI or I2C.
The GHI Electronics ALFAT SoC Processor is a high-performance ARM Cortex-M3 processor designed to provide a FAT file system engine with built-in SD and USB host drivers. It allows host systems to access files on SD cards and USB mass storage devices with minimal resources through UART, SPI, or I2C interfaces. The processor supports FAT16 and FAT32 file systems, including licensed Long File Name (LFN) support from Microsoft, and can access two USB mass storage devices and one memory card simultaneously.
