ALFAT Chip

The ALFAT chip ALFAT™ is a full FAT file system stack that is burned on a powerful 32-bit processor (LPC2114 ARM processor from Philips). ALFAT saves files and directories in on medias in standard FAT file system so the media can be accessed from any other devices that supports FAT file system, a PC, most digital cameras and MP3 players. Simply, send your data to ALFA chip using serial port, SPI or I2C and ALFAT will save your files on MMC, SD, CF or hard drive..

Using ALFAT with SPI and I2C

ALFAT requires very few external components to run. For communication, a simple microcontroller (PIC, AVR, basic stamp…etc.) with UART, SPI or I2C can be used. Also, ALFAT implements two modes for communication, the first one is the text mode. Text mode is a very easy text based commands that are very similar to DOS operating system. The second mode is framed mode. Framed mode is based on data packets, and is more suited for professional applications.

ALFAT is a surface mount device, however we will shortly launch a DIL adapter to allow developers and hobbiest to use the device directly on existing development boards...watch this space!
