 Posted: Mon Sep 06, 2021 12:24 pm Post subject: FRAM lib compatible with both FM25L16B and FM24C16B |
 |
|
I have XMEGA256A3U boards with FM25L16B with a software using "fm25c256.lib"
There is a shortage of FM25L16B, but FM24C16B-G is available so I will make new boards with the FM24C16B-G instead.
Is there a way I can use the same software for both? It seems "fm25c256.lib" is made only for the FM25L16B chip
Both chips seem equivalent except for the max SPI speed (20Mhz in the case of the FM25 and 1MHz for the FM24) but I can't see where is the speed configured in fm25c256.lib |

The FM25xx is SPI and the FM24xx is I2C.
You'll have to change the hardware.

Thanks Klaus!
What a poor analysis I did!
It seems there is no alternative to the FM25L16B then. I'm getting lead times longer than 50 weeks. |

Hello Mark, I need 3 now for prototypes and 200 more this year. I have seen tha Mouser will receive several thousand in October so I will wait.
What I cannot find is XMEGA256A3U. I also need 200 this year.
