AT45DB041B是ATMEL公司推出的一款大容量高速串行flash存储器。它采用2.5-3.0V或2.7-3.6V单电源供电,兼容SPI串行外设接口,可以是活的与各种微处理器接口使用,时钟频率可高达20MHz。其应用几乎不需任何外围器件,电路开发简单,更由于其封装尺寸小、集成度高、电源电压低等优点,在商业和工业中得到了广泛的应用。AT45DB041B典型应用在数字语音存储、图像存储、数据存储以及程序代码存储等场合。
The AT45DB041B is a high-capacity, high-speed serial flash memory from ATMEL. It operates on a single 2.5-3.0V or 2.7-3.6V supply and is compatible with the SPI Serial Peripheral Interface and can be used with a variety of microprocessor interfaces with clock frequencies up to 20MHz. Its application almost does not need any peripheral device, the circuit is simple to develop, more widely used in commerce and industry due to its small package size, high integration and low power supply voltage. AT45DB041B typical applications in digital voice storage, image storage, data storage and program code storage and other occasions.
