3.11 NAND-Flash Controller (NDFC)
3.11.1
Note 1: Error correction needs software processing.
Note 2: The WPn (Write Protect) pin of the NAND Flash is not supported. When this function is needed, prepare it on
the NAND-Flash memory. The NDFC also has an ECC calculation function for error
correction. It supports the Hamming Code ECC calculation method for the NAND-Flash
memory of SLC (Single Level Cell) type that is capable of correction (Note1) a single-bit
error for every 256 bytes and the Reed-Solomon ECC calculation method for the
NAND-Flash memory of MLC (Multi-Level Cell) type that is capable of correction (Note 1)
four error addresses for every 512 bytes.
Overview
The NAND-Flash Controller (NDFC) is provided with dedicated pins for connecting with
The NDFC has the following features:
a. Controls the NAND-Flash memory interface through registers.
b. Supports 8-bit NAND-Flash memory devices (Does not support 16-bit devices).
c. Supports page sizes of 512 bytes and 2048 bytes.
d. Includes an ECC generation circuit using Hamming codes (for SLC type).
e. Includes
f. Provides an Autoload function for high-speed data transfer by using two 32bit × 4word
