Overview
DATA SHEET µPD42S17405L, 4217405L 3.
3 V OPERATION 16 M-BIT DYNAMIC RAM 4 M-WORD BY 4-BIT, EDO MOS INTEGRATED CIRCUIT Description The µPD42S17405L, 4217405L are 4,194,304 words by 4 bits CMOS dynamic RAMs with optional EDO.
EDO is a kind of the page mode and is useful for the read operation.
Besides, the µPD42S17405L can execute CAS before RAS self refresh.
The µPD42S17405L, 4217405L are packaged in 26-pin plastic TSOP (II) and 26-pin plastic SOJ.
