66AK2H14: Maximum NAND flash supported on EMIF16

Hi Madhu,

See www.ti.com/.../sprugz3a.pdf, Section 1.1 Purpose of the Peripheral:
"The EMIF16 module is intended to provide a glue-less interface to a variety of asynchronous memory devices like ASRAM, NOR and NAND memory. A total of 256M bytes of any of these memories can be accessed at any given time via four chip selects with 64M byte access per chip select. NOR Flash can be used for boot purposes. These memories can also be used for Data Logging purposes."
See also the note:
"Note—The 64MB limit per chip select applies only for asynchronous memories that use the EMIF16 address bus for addressing - typically ASRAM and NOR flash. NAND flash uses the data bus as a multiplexed data/address bus and does not use EMIF16 address pins for addressing (Only CLE and ALE signals use the address bus. Refer to Section 3.1 ‘‘NAND Flash Mode’’ for more details). So NAND Flash > 64MB can be supported on one chip select."

Hi Madhu,

You should be able to connect any device actually.

I am not aware of a limitation on No. of pages/page size of the NAND flash, etc..

Most of the nand chips available on the market should be compatible with the EMIF16 interface.

Yordan
