Nope, 2910 is a microprogram address sequencer for the 2901 series.

There are, however, a number of "2901 with more bits" chips, however. The
IDT IDT49402/IDT49410A is the equivalent of 4 2901 slices (16-bits) + the
apropos microprogram sequencer logic. Cypress had the CY7C9101, which was
similar. WSI had the WS59032, which consisted of 8 2901 equivalents.
Innovasic has the IA59032, which is an ASIC reimplimentation of the WSI chip
and is still availible.
