Avoid Timing

M24L28256SA

ESMT Pseudo SRAM has a timing which is not supported at read operation, If your system has multiple invalid address signal

shorter than t

RC

during over 15μs at read operation shown as in Abnormal Timing, it requires a normal read timing at leat during

15μs shown as in Avoidable timing 1 or toggle CE to high (≧t
