大家好,今天小编关注到一个比较有意思的话题,就是关于weflash编程设备使用教程的问题,于是小编就整理了2个相关介绍weflash编程设备使用教程的解答,让我们一起看看吧。
flash芯片读和写原理?
FLASH的读写原理FlashROM 一般是一种单芯的 FlashROM,从读写方式上看可以说是最简单的一种 FlashROM。特点是写入的单位是“页”,且写入新数据之前不需要先擦除其中原有的。
引脚一般有:A0~A16:Address Inputs (地址线的数目与FlashROM 的容量有关)
DQ0~DQ7:Data Inputs/Outputs
#CE:Chip Enable Input (芯片使能)
#OE:Output Enable Input (输出使能)
#WE:Write Enable Input
Figure 2-1 Vdd:Power Supply
GND:Ground

There is a need for us protection of the environment.
We can do a lot of things.Firstly,we can use more cloth bags instead of use plastic bags.Secondly,We should walk much,use lifts and cars less as well as possible.
