That looks about right for that chip. You should have save available though! Maybe you need to have some code in the window for that. Looks like most of the greyed out options are for the in circuit debuger. Some other chips: 16F627(A), 16F628(A), 16F73, 16F74, 16F76, 16F77, 16F870, 16F871, 16F873(A), 16F874(A), 16F876(A), 16F877(A), 16F87, 16F88, 18F242, 18F248, 18F252, 18F258, 18F442, 18F448, 18F452, 18F458, 18F1220, 18F1320, 18F2220, 18F2320, 18F4220, 18F4320, 18F6620 and 18F8620

have an in circuit debug available for them, but as you can see, they are a bit limited. It is an interesting feature though.
