Introduction
This chapter contains electrical and timing specifications for the MC9S08QA4 series of microcontrollers available at the time
of publication.
3.2
Absolute Maximum Ratings
Absolute maximum ratings are stress ratings only, and functional operation at the maxima is not guaranteed. Stress beyond the
limits specified in Table 2 may affect device reliability or cause permanent damage to the device. For functional operating
conditions, refer to the remaining tables in this section.
This device contains circuitry protecting against damage due to high static voltage or electrical fields; however, it is advised
that normal precautions be taken to avoid application of any voltages higher than maximum-rated voltages to this
high-impedance circuit. Reliability of operation is enhanced if unused inputs are tied to an appropriate logic voltage level (for
instance, either VSS or VDD) or the programmable pullup resistor associated with the pin is enabled.

Input must be current limited to the value specified. To determine the value of the required
current-limiting resistor, calculate resistance values for positive (VDD) and negative (VSS) clamp
voltages, then use the larger of the two resistance values.
2 All functional non-supply pins are internally clamped to V
SS and VDD.
3 Power supply must maintain regulation within operating V
DD range during instantaneous and
operating maximum current conditions. If positive injection current (VIn > VDD) is greater than
IDD, the injection current may flow out of VDD and could result in external power supply going
out of regulation. Ensure external VDD load will shunt current greater than maximum injection
current. This will be the greatest risk when the MCU is not consuming power. Examples are: if
no system clock is present, or if the clock rate is very low (which would reduce overall power
consumption).
3.3
Thermal Characteristics
This section provides information about operating temperature range, power dissipation, and package thermal resistance. Power
dissipation on I/O pins is usually small compared to the power dissipation in on-chip logic and voltage regulator circuits, and
it is user-determined rather than being controlled by the MCU design. To take PI/O into account in power calculations, determine
the difference between actual pin voltage and VSS or VDD and multiply by the pin current for each I/O pin. Except in cases of
unusually high pin current (heavy loads), the difference between pin voltage and VSS or VDD will be very small.

The average chip-junction temperature (TJ) in °C can be obtained from:
TJ = TA + (PD × θJA)
Eqn. 1
where:
—
—
—
—
—
TA = Ambient temperature, °C
θJA = Package thermal resistance, junction-to-ambient, °C/W
PD = Pint + PI/O
Pint = IDD × VDD, Watts — chip internal power
PI/O = Power dissipation on input and output pins — user-determined
For most applications, PI/O << Pint and can be neglected. An approximate relationship between PD and TJ (if PI/O is neglected)
is:
PD = K ÷ (TJ + 273°C)
Eqn. 2
Solving Equation 1 and Equation 2 for K gives:
K = PD × (TA + 273°C) + θJA × (PD)2
Eqn. 3
where K is a constant pertaining to the particular part. K can be determined from Equation 3 by measuring PD (at equilibrium)
for a known TA. Using this value of K, the values of PD and TJ can be obtained by solving Equation 1 and Equation 2 iteratively
for any value of TA.
3.4
ESD Protection and Latch-Up Immunity
Although damage from electrostatic discharge (ESD) 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 AEC-Q100 Stress Test Qualification for Automotive Grade Integrated Circuits. During
the device qualification ESD stresses were performed for the human body model (HBM), the machine model (MM) and the
charge device model (CDM).

A device is defined as a failure if after exposure to ESD pulses the device no longer meets the device specification. Complete
DC parametric and functional testing is performed per the applicable device specification at room temperature followed by hot

Input must be current-limited to the value specified. To determine the value of the required current-limiting resistor, calculate
resistance values for positive and negative clamp voltages, then use the larger of the two values.

Power supply must maintain regulation within operating VDD range during instantaneous and operating maximum current
conditions. If positive injection current (VIn > VDD) is greater than IDD, the injection current may flow out of VDD and could result
in external power supply going out of regulation. Ensure external VDD load will shunt current greater than maximum injection
current. This will be the greatest risk when the MCU is not consuming power. Examples are: if no system clock is present, or if
clock rate is very low (which would reduce overall power consumption).

Data in Typical column was characterized at 3.0 V, 25°C.
This is the shortest pulse that is guaranteed to be recognized.
3
This is the minimum pulse width that is guaranteed to pass through the pin synchronization circuitry. Shorter pulses may or
may not be recognized. In stop mode, the synchronizer is bypassed so shorter pulses can be recognized in that case.
4 Timing is shown with respect to 20% V
DD and 80% VDD levels. Temperature range –40°C to 85°C.
5 To enter BDM mode following a POR, BKGD/MS should be held low during the power-up and for a hold time of t

rises above VLVD.

The frequency of this clock is controlled by a software setting.
These values are hardware state machine controlled. User code does not need to count cycles. This information supplied for
calculating approximate time to program and erase.
3 Typical endurance for flash was evaluated for this product family on the 9S12Dx64. For additional information on how
Motorola defines typical endurance, please refer to Engineering Bulletin EB619/D, Typical Endurance for Nonvolatile Memory.
4 Typical data retention values are based on intrinsic capability of the technology measured at high temperature and de-rated
to 25°C using the Arrhenius equation. For additional information on how Freescale defines typical data retention, please refer
to Engineering Bulletin EB618/D, Typical Data Retention for Nonvolatile Memory.
