NAND Flash Memory Interface
The KSZ9692PB, KSZ9692PB-S NAND controller provides interface to external NAND Flash memory. A total of two
banks are supported. NAND Flash bank0 can be configured by power-up strap option to operate as boot bank. Both
NAND Flash banks share data bus with FLASH/ROM/SRAM memory banks.
• Glueless connection to two banks with programmable 8 or 16 bit data width and programmable access timing
• Hardware ECC not supported
• Small page size 512 + 16 bytes
• Large page size 2048 + 64 bytes
• Large and small block size
•Boot option with automatic page crossing where pages are automatically opened sequentially by hardware
•Boot option with two 8-bit device in parallel to form a 16-bit bank
•Boot option with bank0 and bank1 as active banks in cascade
• Support for following device densities:
− 64Mbit
− 128Mbit
− 256Mbit
− 512Mbit
− 1Gbit
− 2Gbit
− 4Gbit
− 8Gbit
The following figures illustrate examples of NAND Flash bank configuration:
