15.3. NAND Flash Controller Signal Descriptions

All NAND pins have to be from one of the following categories:
  • HPS I/O
  • FPGA I/O
The following table lists all NAND Flash pin options available to both the HPS and FPGA.
Table 103.  NAND Flash Pin Options
Pins Supported Data Width Supported Number of CE and R/B
HPS Pins 8-bit or 16-bit 1
FPGA Pins 8-bit or 16-bit 1 – 4
If you are required to connect multiple NAND devices, you must route the NAND interface to FPGA logic. If you use HPS pins, you can only use one CE and R/B pair. If you use FPGA pins, you can use multiple CE and R/B pairs.
Note: The options are mutually exclusive, which means you cannot use HPS pins, and route the CE and R/B signals to FPGA pins.
