ATMEL 爱特梅尔公司串行FLASH 存储器 25Fxxx 是爱特梅尔串行Flash系列的最新一代的产品,提供高速(20 兆赫), 低引脚数(8个引脚) 和低电压(2.7V-3.6V) 串行接口的存储器。爱特梅尔的高速, 低电压的串行Flash存储器系列提供兼容用于串行EEPROM的SPI接口。这就允许最终用户可以把他们的板子上的小容量的串行EEPRO灵活的更新为大容量的串行Flash,而不需要改动电路板的布局。
串行Flash的应用非常多,包括个人计算机添加卡、图形卡, 和NIC 卡(网络接口卡) 。串行Flash也被许多卡驱动器制造厂商用来代替标准并行Flash,通过减少ASIC的引脚数以降低整体的成本。爱特梅尔的串行Flash的容量从512 Kbits到4Mbits 。
The AT25Fxxx, AT25FSxxx and AT26F/DFxxx series of products are pin compatible to our complete offering of SPI serial EEPROMs. This gives you the flexibility of increasing your memory size from a low-density serial EEPROM device to a serial Flash without any changes to your board layout.
The full-featured AT45DBxxx DataFlash family is taking SPI serial Flash to the next level. Advanced features to further enable system integration, robustness and cost reduction include a 128-byte security register, individual sector protection, and a permanent lockdown feature. This popular page erase architecture allows key software routines, parameters and user data to be stored more efficiently, so that more memory space isn't wasted by allocating large sectors for different types of code or data.
