Application Note
MC68HC908AS60A/AZ60A vs. MC68HC908AS60/AZ60
4
The MC68HC908AS60A/AZ60A devices discussed in this application
note are a technology shrink from the previous MC68HC908AS60/AZ60
devices.
In addition to the transistor size reduction, a few changes were made on
the devices. These include:
