DESCRIPTION

The µPD70F3040 and µPD70F3040Y are products that substitute flash memory for the mask ROM of the µPD703039, 703040, 703041 and µPD703039Y, 703040Y, 703041Y, respectively. Since the µPD70F3040 and 70F3040Y can be read and written while mounted on the board, these products are ideal for evaluation during system development, multiple-version small-scale production or quick product release.
