PSRAM Size

[arunkrishnan]

Whats the maximum PSRAM size that teensy 4.1 can support.
In the PJRC website, I am seeing the part number APS6404L_3SQR. So I am assuming max supported is 64MB.
Is it correct?
Thanks in advance.

Usable/Supported and available PSRAMS are either 8MB or now 16MB. Using two of those in combination would yield a maximum of 32 MB

Hi,
Thank you for the reply.

Model numbers usually reference the number of bits, not bytes. APS6404 is 64 megabits = 8 megabytes.
