Hello AFVR.
This is a good question. I looked only at the MC9S08GB/GT manual, it includes a statement on ESD on page 259, section A4. I'll patch it in here:
"
Electrostatic Discharge (ESD) Protection Characteristics
A.4 Electrostatic Discharge (ESD) Protection Characteristics
Although damage from static discharge is much less common on these devices than on early CMOS
circuits, normal handling precautions should be used to avoid exposure to static discharge. Qualification
tests are performed to ensure that these devices can withstand exposure to reasonable levels of static
without suffering any permanent damage. All ESD testing is in conformity with CDF-AEC-Q00 Stress
Test Qualification for Automotive Grade Integrated Circuits. (http://www.aecouncil.com/) This devicewas
qualified to AEC-Q100 Rev E. A device is considered to have failed if, after exposure to ESD pulses, the
device no longer meets the device specification requirements.
"
As a personal statement I've been designing Freescale/Motorola microcontrollers into embedded products for more than 15 years and have never had a known ESD failure.
