Electrical Characteristics
This section contains the most accurate electrical information for the MC9S12NE64
microcontroller available at the time of publication. The information is subject to change.
This introduction is intended to give an overview on several common topics like power supply,
current injection etc.
A.1
The electrical parameters shown in this supplement are guaranteed by various methods. To give
the customer a better understanding the following classification is used and the parameters are
tagged accordingly in the tables where appropriate, under the “C” column heading.
P: Those parameters are guaranteed during production testing on each individual device.
C: Those parameters are achieved by the design characterization by measuring a statistically
relevant sample size across process variations. They are regularly verified by production monitors.
T: Those parameters are achieved by design characterization on a small sample size from typical
devices. All values shown in the typical column are within this category.
D: Those parameters are derived mainly from simulations.
A.2
The MC9S12NE64 uses several pins to supply power to the I/O ports, A/D converter, oscillator
and PLL, the Ethernet Physical Transceiver (EPHY), as well as the digital core.
