4 4. Although each I/O port can sink more than the test conditions (1 ma at CC = 5, 5 ma at CC = 3) under steady state conditions (non-transient), the sum of all I OL, for all ports, should not exceed 6 ma. If I OL exceeds the test condition, OL may exceed the related specification. Pins are not guaranteed to sink current greater than the listed test condition. 5. Although each I/O port can source more than the test conditions (1 ma at CC = 5, 5 ma at CC = 3) under steady state conditions (non-transient), the sum of all I OH, for all ports, should not exceed 6 ma. If I OH exceeds the test condition, OH may exceed the related specification. Pins are not guaranteed to source current greater than the listed test condition. 6. The RESET pin must tolerate high voltages when entering and operating in programming modes and, as a consequence, has a weak drive strength as compared to regular I/O pins. See Figure 3-19, Figure 3-2, Figure 3-21, and Figure 3-22 (starting on page 18). 7. alues are with external clock using methods described in Minimizing Power Consumption on page 37. Power Reduction is enabled (PRR = xff) and there is no I/O drive. 8. Brown-Out Detection (BOD) disabled. 2.2 Clock Characteristics Calibrated Internal RC Oscillator Accuracy It is possible to manually calibrate the internal oscillator to be more accurate than default factory calibration. Please note that the oscillator frequency depends on temperature and voltage. oltage and temperature characteristics can be found in Figure 3-36 on page 27 and Figure 3-37 on page 27. Table 2-2.

BOT may be below nominal minimum operating voltage for some devices. For devices where this is the case, the device is tested down to CC = BOT during the production test. This guarantees that a Brown-out Reset will occur before CC drops to a voltage where correct operation of the microcontroller is no longer guaranteed. 2.5 Serial Programming Characteristics Table 2-5.

9 ATtiny25 3. Typical Characteristics 3.1 Active Supply Current The data contained in this section is largely based on simulations and characterization of similar devices in the same process and design methods. Thus, the data should be treated as indications of how the part will behave. The following charts show typical behavior. These figures are not tested during manufacturing. All current consumption measurements are performed with all I/O pins configured as inputs and with internal pull-ups enabled. A sine wave generator with rail-to-rail output is used as clock source. The power consumption in Power-down mode is independent of clock selection. The current consumption is a function of several factors such as: operating voltage, operating frequency, loading of I/O pins, switching rate of I/O pins, code executed and ambient temperature. The dominating factors are operating voltage and frequency. The current drawn from capacitive loaded pins may be estimated (for one pin) as C L * CC *f where C L = load capacitance, CC = operating voltage and f = average switching frequency of I/O pin. The parts are characterized at frequencies higher than test limits. Parts are not guaranteed to function properly at frequencies higher than the ordering code indicates. The difference between current consumption in Power-down mode with Watchdog Timer enabled and Power-down mode with Watchdog Timer disabled represents the differential current drawn by the Watchdog Timer.
