PSOC5 CY8C5268AXI-LP047 vs CY8C5246LTI-029

[sujoy]

Hi, 

We have recently (5 months back) developed a board that uses CY8C5268AXI-LP047 which is currently out of stock everywhere. We need 15 more pieces of the microcontroller and one of our suppliers has CY8C5246LTI-029 (which is obsolete) in stock. Can we use this as a replacement to the 5268?

The two microcontrollers are pin compatible and have mostly the same peripherals. There is a huge difference in the Flash and Ram size but we are using only 10kB of Flash, 3kB of SRAM, Stack 2048 bytes and heap 128 bytes so it seems that both the microcontrollers have more than enough capacity for out requirement. 

Please let me know if there are any reasons why we can't/ shouldnt use the older micro (CY8C5246LTI-029). I understand it is obsolete but our volumes are low enough that redesigning is more expensive than replacing microcontrollers.

Also I could not find it on PSOC creator -4 do I need an older version to program CY8C5246LTI-029?

Thanks in Advance,

Sujoy.

Hello.

I can't answer all your questions but, I can say that 5246 is not shown in the Device Selector list for Creator 3.1.  You have to go back to Creator 2.xx.

An archive of previous Creator releases is here:

The good news is, 5246 is supported in PSoC Programmer 3.28 (under device selector CY8C55xx).

Hi @sujoy 

It is not recommended to use the CY8C5246LTI-029 for any design. This is the PSoC 5 part which has been completely replaced with the PSoC 5LP part. Please see this article - https://www.cypress.com/products/psoc-5. 

Kindly use the PSoC 5LP part for all new designs.

Best regards, 
Hari

Dear @Hari,

If you can get me 15 pieces of CY8C5268AXI-LP047 or a suitable replacement then I'd ofcourse prefer to use the newer part. 
The question arises out of the microcontroller shortage 🙂

Hi @sujoy 

I understand the concern here, but can you please create a case in the Customer Marketing section from the following link:

Cypress web page (https://www.cypress.com)-->Design support--> Support --> Create a support case and in that, you can create a customer marketing case. The marketing team will be able to help you with the lead time for PSoC 5LP parts. Please mention a list of the MPNs (100TQFP package) that would be applicable for your design.

Best regards, 
Hari
