Hi, is there any analogue of the LY68L6400SLIT chip? On the JLCPCB website, these chips are marked as out of stock.

I also had to look around, and I found the APS6404L-3SQR-SN from AP Memory, which seems (to my limited knowledge) compatible with the Lyontek: both 64Mbit, SOP-8, same pinout, and in the datasheet they seem to support the same set of read/write commands

Mouser: APS6404L-3SQR-SN , Datasheet

I haven't been able to test this yet, so can't really say for sure. Hopefully someone could confirm ?

APS6404L-3SQR-SN

Unfortunately, this chip is also not available on the JLCPCB website.

I've built a PicoGUS (v1.x) using a APS6404L-3SQR-SN which I sourced from Aliexpress - AE item number 1005003308679029. But of course, the buyer is taking certain chances by using such source - I can only anecdotally report that it worked for me.
