ATmega3209/4809 – 48-pin Data Sheet Electrical Characteristics 5. Electrical Characteristics 5.1 Absolute Maximum Ratings
Stresses beyond those listed in this section may cause permanent damage to the device. This is a stress rating only and functional operation of the device at these or other conditions beyond those indicated in the operational sections of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.
Table 5-1. Absolute Maximum Ratings Symbol Description Conditions Min. Max. Unit
VDD Power Supply Voltage -0.5 6 V IVDD Current into a VDD pin TA=[-40, 85]°C - 200 mA TA=[85, 125]°C - 100 mA IGND Current out of a GND pin TA=[-40, 85]°C - 200 mA TA=[85, 125]°C - 100 mA VPIN Pin voltage with respect to GND -0.5 VDD+0.5 V IPIN I/O pin sink/source current -40 40 mA I (1) c1 I/O pin injection current except for the RESET pin -1 1 mA Vpin<GND-0.6V or 5.5V<Vpin≤6.1V 4.9V<VDD≤5.5V I (1) c2 I/O pin injection current except for the RESET pin -15 15 mA Vpin<GND-0.6V or Vpin≤5.5V VDD≤4.9V Tstorage Storage temperature -65 150 °C
Note: 
1. – If VPIN is lower than GND-0.6V, then a current limiting resistor is required. The negative DC injection current limiting resistor is calculated as R = (GND-0.6V – Vpin)/ICn. – If VPIN is greater than VDD+0.6V, then a current limiting resistor is required. The positive DC injection current limiting resistor is calculated as R = (Vpin-(VDD+0.6))/ICn.
5.2 General Operating Ratings
The device must operate within the ratings listed in this section in order for all other electrical characteristics and typical characteristics of the device to be valid.
Table 5-2. General Operating Conditions Symbol Description Condition Min. Max. Unit
VDD Operating Supply Voltage 1.8(1) 5.5 V TA Operating temperature range Standard temperature range -40 125 °C
Note: 
1. Operation is guaranteed down to 1.8V or VBOD with BODLEVEL=1.8V, whichever is lower. © 2018 Microchip Technology Inc.
