1. Introduction
Adding FAT file system to products requires a lot of resources from the system and needs
intensive development efforts. This also requires USB Host drivers and SD memory drivers
to be able o access storage medias such as SD cards or USB Mass Storage devices.
Additionally, licensing patented technologies, such as LFN is a lengthy and expensive
process. Thanks to ALFAT SoC Processor, any simple system can now access files on SD
cards and USB memory drives in a very short time, with minimal resources through simple
UART, SPI or I2C interface. ALFAT SoC processor is capable of accessing two USB mass
storage devices and one memory card simultaneously. This gives the user unique features
such as copying data from one media to another.
The Host MCU controls ALFAT through simple commands sent through UART (serial), SPI
or I2C. The commands give the host MCU the ability to access files on the storage media.
With ALFAT, file access rate can reach 4000 KBytes/sec.
An important advantage of ALFAT is that supports Long File Name LFN and it is licensed
by Microsoft for commercial use. Solutions that depends on ALFAT can use LFN
commercially without the need for any additional licensing.
