Appendix A
Electrical Characteristics
NOTE
The MC9S12NE64 is specified and tested at the 3.3-V range.
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 Parameter Classification
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 Power Supply
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.
• The V_DDA, V_SSA pair supplies the A/D converter and portions of the EPHY
• The V_DDX1, V_DDX2, V_SSX1, V_SSX2 pairs supply the I/O pins, and internal voltage regulator
• The V_DDR supplies the internal voltage regulator, and is the V_REGEN signal
• V_DD1, V_SS1, V_DD2, and V_SS2 are the supply pins for the digital logic
• V_DDPLL, V_SSPLL supply the oscillator and the PLL
• V_SS1 and V_SS2 are internally connected by metal
• V_DD1 and V_DD2 are internally connected by metal
• PHY_VDDA, PHY_VSSA are power supply pins for EPHY analog
• PHY_VDDRX, PHY_VSSRX are power supply pins for EPHY receiver
