The S08QE is an S08 8-bit microcontroller subfamily.

It is closely related to the S08QG but has a few more features (and fewer silicon errata!). Like the QG, the QE parts have an operating range of 1.8V to 3.6V.

If you are looking for a versatile, inexpensive, general-purpose 8-bit microcontroller, and are sold on the S08 architecture, this should be your go-to part.

The S08QE is really three sub-subfamilies:

QE4 and QE8


QE16 and QE32


QE64, QE96, and QE128
