    Teensy 4.1 PSRAM Random Access Latency

    Thanks everyone for the helpful suggestions. I dug in a bit more to understand the performance of different access patterns and to understand how data gets fetched from PSRAM. It seems data is fetched in 32 byte bursts from the PSRAM. This lines up with the data sheet for one of the compatible...

    Teensy 4.1 PSRAM Random Access Latency

    My question is around latency limitations of the PSRAM on the Teensy 4.1 in regards to random access. I was hoping to achieve worst case sub-microsecond tiny random access reads (reading a single byte) from the PSRAM. The majority of the time, I experience sub-microsecond reads (well below...
