SPI接口的FLASH ROM AT45DB161D的驱动方法

AT45DB161D允许简单的在系统重新编程，而无需输入高编程电压。芯片可以采用2.5V~3.6V或2.7V~3.6V单电源供电，进行编程与读取操作。它可以通过#CS来进行使能，并通过三线接口（SI、SO、SCK）进行数据通信。-To allow for simple in-system reprogrammability, the AT45DB161D does not require high input

voltages for programming. The device operates from a single power supply, 2.5V to 3.6V or 2.7V

to 3.6V, for both the program and read operations. The AT45DB161D is enabled through the

chip select pin (CS) and accessed via a three-wire interface consisting of the Serial Input (SI),

Serial Output (SO), and the Serial Clock (SCK).
