UPD42S17405LLA-A60 3.3V OPERATION 16M-BIT DYNAMIC RAM

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) an.
