■ HANDLING DEVICES
Special care is required for the following when handling the device:
Latch-up prevention
Unused pins handling
External clock usage
Unused sub clock signal
Notes on PLL clock mode operation
Power supply pins (VCC/VSS)
Crystal oscillator circuit
Turn on sequence of power supply to A/D converter and analog inputs
Pin handling when not using the A/D converter
Notes on energization
Stabilization of power supply voltage
1.
Latch-up prevention
CMOS IC chips may suffer latch-up under the following conditions:
A voltage higher than VCC or lower than VSS is applied to an input or output pin.
A voltage higher than the rated voltage is applied between VCC and VSS.
The AVCC power supply is applied before the VCC voltage.
Latch-up may increase the power supply current dramatically, causing thermal damages to the device.
For the same reason, extra care is required to not let the analog power-supply voltage (AVCC, AVRH) exceed
the digital power-supply voltage.
2.
Unused pins handling
Unused input pins can be left open when the input is disabled (corresponding bit of Port Input Enable register
PIER = 0).
Leaving unused input pins open when the input is enabled may result in misbehavior and possible permanent
damage of the device. They must therefore be pulled up or pulled down through resistors. To prevent latch-
up, those resistors should be more than 2 k
.
Unused bidirectional pins can be set either to the output state and be then left open, or to the input state with
either input disabled or external pull-up/pull-down resistor as described above.
3.
External clock usage
The permitted frequency range of an external clock depends on the oscillator type and configuration. See AC
Characteristics for detailed modes and frequency limits. Single and opposite phase external clocks must be
connected as follows:
1. Single phase external clock
When using a single phase external clock, X0 pin must be driven and X1 pin left open.
2. Opposite phase external clock
X0
X1
