Device Overview

The MC9S08SG8 members of the low-cost, high-performance HCS08 family of 8-bit microcontroller

units (MCUs). All MCUs in the family use the enhanced HCS08 core and are available with a variety of

modules, memory sizes, memory types, and package types. The high-temperature devices have been

qualified to meet or exceed AEC Grade 0 requirements to allow them to operate up to 150 °C TA.
