Part Number: 66AK2E05

Hi, all

Now I am using 66ak2e5 processer which have one EMIF16 peripheral.

And I want to use two independent interfaces of EMIF16 peripheral e.g. EMIF16A, EMIF16B....

Does anyone know any model of DSP to support my requirement?

Thanks a lot.

Jacky,

EMIF16 peripheral, itself will support upto 4 chip selects.

Would you please expand the need for two EMIF16 interface?

I believe, you also know that there is another DDR3_EMIF in K2E, addition to EMIF16.

---

As far as I know, all the keystone I and II devices has only one EMIF16.

-- I have strict timing control on my design, so need control two EMIF16 at the same time. (One for access NAND Flash, One for communication with FPGA)

I don't think it can expand the need for two EMIF16.

-- Yes, I know that. But it uses for DDR3 memory which I also need on my Linux system.

-- Thanks for your information. I also cannot find on keystone serial. Do know other serial IC has two EMIF16 ?

Thanks again.

No, Jacky.

I don't think so

Jacky,

AM69x Processors has four EMIF32 but it has no DSP on it.

They are ARM only cores.

• Up to Four External Memory Interface (EMIF) module with ECC – Supports LPDDR4 memory types – Supports speeds up to 4266 MT/s – Up to 4x32-b bus with inline ECC up to 68 GB/s

https://www.ti.com/lit/ds/symlink/am69a.pdf

Similarly, AM68x 64-bit processors has two EMIF32 ( AM68x 64-Bit Jacinto 8 TOPS Vision SoC Processor ) with no DSP in it.

Up to two External Memory Interface (EMIF) modules with ECC
- Supports LPDDR4 memory types
- Supports speeds up to 4266MT/s
- Up to two 32-bit data buses with inline ECC up to 17GB/s per EMIF

Regards

Shankari

Hi, Shankari

Thanks for your information.

Reading datasheet of AM69x and AM68x processors now.
