AT45DB041D SPI NAND Flash driver

atruntime.com

The serial-interface sequential access flash memory ideally suited for a wide variety of digital voice, image, program code, and data storage applications. The flash memory also contains two SRAM buffers of 256 or 264bytes each that receive data while a page in the main memory is reprogrammed, as well as writing a continuous data stream. Now, you can use it with your favorite PIC MCU. Again, I'm using sw SPI for portability.

About this Code Example

#include <p30f3011.h>
#include "NAND_FLASH_Driver.h"

void main (void)
{

    InitNandFlash();  //Init AT45DB041D NAND Flash memory
    
    int mem_page=0; 

    main_mem_page_to_buffer(mem_page); //copy from mem page(NAND) to buffer1(RAM)
     
    write_to_buffer(0,0xFF);   //write 0xFF in 0 location
    write_to_buffer(1,0xAA);   //wirte 0xAA in 1 location
 
    buffer_to_main_mem_page(mem_page); //copy from buffer1(RAM) to mem page(NAND) 
 
    while(1);
    
}
