LPC Microcontrollers中的主题 External Nand Flash for LPC2148 https://community.nxp.com/t5/LPC-Microcontrollers/External-Nand-Flash-for-LPC2148/m-p/740201#M29853 <HTML><HEAD></HEAD><BODY><P>Hi,<BR />I have a LPC2148 board and I want to add an external NAND flash card to it. I have two questions:<BR />1. Is this possible and can be done by soldering GPIO pins of the board to the Flash chip pins. My flash chip is the "chip select don't care" type.<BR />2. How do I find the pin numbering on the board, i.e. which pin number goes where? Is there a schematic?</P></BODY></HTML> Sun, 21 Jan 2018 06:53:23 GMT abhishekjoshi 2018-01-21T06:53:23Z External Nand Flash for LPC2148 https://community.nxp.com/t5/LPC-Microcontrollers/External-Nand-Flash-for-LPC2148/m-p/740201#M29853 <HTML><HEAD></HEAD><BODY><P>Hi,<BR />I have a LPC2148 board and I want to add an external NAND flash card to it.

For example, if you are using the Embedded Artits “LPC2148 USB QuickStart Board”, the information is available on the following link:</P><P><A href="https://www.embeddedartists.com/products/boards/lpc2148.php">https://www.embeddedartists.com/products/boards/lpc2148.php</A></P><P>&nbsp;</P><P>Hope this will be useful for you.</P><P>Best regards!</P><P>/Carlos</P><P></P><P>-----------------------------------------------------------------------------------------------------------------------<BR />Note: If this post answers your question, please click the Correct Answer button.
