The S08QG is an S08 8-bit microcontroller subfamily.

I was initially interested in using one, way back in 2006, for my Spoken Word project. (I never built that, but I’d still like to.)

The chips have some curious errata; the most serious one involves the internal clock source (ICS), and prevents it from running full-bore (at 10 MHz). Freescale suggest running the chip at 5 MHz instead, which is perhaps fine for that application, but in general is a bit disappointing. The DIP packaged QE4 and QE8 are probably better choices. They are a tiny bit more expensive than their QG cousins, but also have more features; in particular, they have more timer channels.

A few features:
