Make sure you google for uPD7220 (that's the NEC
prefix)
Note that the Intel 7220 (usually D7220 or P7220) is completely
incompatible, as it is a bubble memory controller for the Intel
1 Mbit bubble memory parts.
Someone else already pointed out that the Intel's equivalent
of the NEC uPD7220 was the Intel 82720.
