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. During the device qualification ESD stresses were performed for the human body model (HBM), the machine model (MM), and the charge device model (CDM). All latch-up testing is in conformity with AEC-Q100 Stress Test Qualification. 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 as per the applicable device specification at room temperature followed by hot temperature, unless specified otherwise in the device specification.

All 5 volt tolerant digital I/O pins are internally clamped to VSS through a ESD protection diode. There is no diode connection to VDD. If VIN greater than VDIO_MIN (= VSS–0.3 V) is observed, then there is no need to provide current limiting resistors at the pads. If this limit cannot be observed, then a current limiting resistor is required. 4. I/O is configured as push-pull mode. 8 General 8.1 General characteristics The device is fabricated in high-density, low-power CMOS with 5 V–tolerant TTLcompatible digital inputs, except for the RESET pin which is 3.3V only. The term “5 V– tolerant” refers to the capability of an I/O pin, built on a 3.3 V–compatible process technology, to withstand a voltage up to 5.5 V without damaging the device. 5 V–tolerant I/O is desirable because many systems have a mixture of devices designed for 3.3 V and 5 V power supplies. In such systems, a bus may carry both 3.3 V– and 5 V– compatible I/O voltage levels (a standard 3.3 V I/O is designed to receive a maximum voltage of 3.3 V ± 10% during normal operation without causing damage). This 5 V– tolerant capability therefore offers the power savings of 3.3 V I/O levels combined with the ability to receive 5 V levels without damage. Absolute maximum ratings in Table 5 are stress ratings only, and functional operation at the maximum is not guaranteed. Stress beyond these ratings may affect device reliability or cause permanent damage to the device. Unless otherwise stated, all specifications within this chapter apply over the temperature range of -40°C to 105°C ambient temperature over the following supply ranges: VSS=VSSA=0V, VDD=VDDA=3.0V to 3.6V, CL≤50 pF, fOP=80MHz. CAUTION This device contains protective circuitry to guard against damage due to high static voltage or electrical fields. However, normal precautions are advised to avoid application of any voltages higher than maximum-rated voltages to this highimpedance circuit. Reliability of operation is enhanced if unused inputs are tied to an appropriate voltage level. MC56F8455X / MC56F8454X Data Sheet, Rev. 3, 06/2014.

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 userdetermined rather than being controlled by the MCU design. To account for PI/O 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 is very small.
