Produktbeschreibung

Das uALFAT ist ein ARM Controller mit integrierten FAT Dateisystem, dieser unterstützt das direkt Ánschlieen einer SD (microSD) Karte oder eines USB Speichers. Der Controller selbst kann über SPI/USART/I2C kommunizieren.



uALFAT™, pronounced micro ALFAT, is a Microsoft licensed FAT file system chipset supporting Long File Names (LFN), SD and USB storage devices are also supported. Communication with uALFAT is done over SPI/USART/I2C through a simple command set.
