三星K9F1G08U0E（128MB,NANDFLASH）STM32平台驱动程序

（模拟时序）

STM32平台下模拟时序驱动K9F1G08U0E，主要目的为了解、学习NAND FLASH的功能特性，没有使用STM32的FSMC（火龙开发板硬件

为模拟时序驱动），纯粹自娱自乐，如对你有帮助，不胜荣幸，呵呵。

C文件内容：

1 #include "NAND512W3A2C.h"

2 /*

3 作者:毕小乐

4 日期:2019.01.24

5 版本:V1.00

7 驱动代码针对K9F1G08U0E时序而写，K9F1G08U0E与NAND512W3A2C,Pin to Pin兼容。

8 驱动运行平台STM32F103。

9 驱动实现功能：

10 1）Page Read

11 2) Page Program

12 3) Block Erase

13 4) Read Status

14 5) Read ID

15 PE0~PE7 -> DB00~DB07

16 PD6 -> CL

17 PD5 -> AL

18 PD14 -> W

19 PD15 -> R

20 PD7 -> CS

21 PB5 -> R/B
