680 / 923 page  Rev. 2.00, 09/03, page 650 of 890 Table 21.3 Permissible Output Currents Conditions: VCC = 3.0 V to 3.6 V, AVCC = 3.0 V to 3.6 V, VREF = 3.0 V to AVCC, VSS = AVSS = 0 V, Ta = –20°C to +75°C (regular specifications), Ta = –40°C to +85°C (wide-range specifications) Item Symbol Min Typ Max Unit Ports 1, 2, and 5 — — 10 mA Permissible output low current (per pin) Other output pins IOL —— 2.0 mA Permissible output low current (total) Total of 20 pins in Ports 1, 2, and 5 ΣIOL —— 80 mA Total of all output pins, including the above — — 120 mA Permissible output high current (per pin) All output pins | –IOH |— — 2.0 mA Permissible output high current (total) Total of all output pins | – ΣIOH |— — 40 mA Notes: 1. To protect chip reliability, do not exceed the output current values in table 21.3. 2. When directly driving a darlington pair or LED, always insert a current-limiting resistor in the output line, as shown in figures 21.1 and 21.2. |
