AT52BC6402A(T)

The 16-Mbit PSRAM has a timing which is not supported at read operation. If your sys-

tem has multiple invalid address signal shorter than tRC during over 48 µs at read

operation which showed in abnormal timing, it needs a normal read timing at least dur-

ing 48 µs which showed in Avoidable Timing(1) or toggle the CS1 to high (> tRC) one

time at least which showed in Avoidable Timing(2)
