If the JTAG interface is enabled, the pull-up resistors. Dqtasheet inputs, Port D pins that are atmeg3a23 pulled low will source current if the pull-up resistors are activated. When pins PA0 to PA7 are used as inputs and are externally pulled low, they will source current if the internal pull- up resistors are activated. All the 32 registers are directly connected to the Arithmetic Logic Unit ALUallowing two independent registers to be accessed in one single instruction executed in one clock cycle.
The Port B output buffers can sink 20 mA. See page for details on operation of the ADC. This allows very fast start-up combined with low-power consumption. As inputs, Port B pins that are externally. The ATmega provides the following features: In Power-save mode, the asynchronous timer continues to run, allowing the user to maintain a timer base while the rest of the device is sleeping.
If the ADC is used, it should be con. When pins PA0 to PA7 are. See page for details on operation of the. The Port Datasheeet pins are tri-stated when a reset condition becomes active, even if the clock is not running. The Power-down mode saves the register contents but. The Port B pins are.

For ADC operations, a voltage in the range 2. If the board has a separate analog ground plane, this pin should be con- nected to this ground plane. As inputs, Port B pins that are externally pulled low will source current dataasheet the pull-up resistors are activated. Input to the inverting Oscillator amplifier and input to the internal datssheet operating circuit.
The AVR core combines a rich instruction set with 32 general purpose working registers. The Port C output buffers can sink 20 mA.

The resulting architecture is more code efficient while achieving throughputs up to ten times faster than conventional CISC microcontrollers. Otherwise, connect to GND. The Port A output.
Shorter pulses are not guaranteed to generate a Reset. In Extended Standby mode, both the main Oscillator and the asynchronous timer continue to run. As inputs, Port D pins that are externally. Port D also serves the functions of various special features of the ATmega as listed on page The Port D pins are. Oscillator, an SPI serial port, and six software selectable power saving modes.
Port B also serves the functions of various special features of the ATmega as listed on page The Power-down mode saves the register contents but freezes the Oscillator, disabling all other chip functions until the next interrupt or Hard- ware Reset. The Port C pins are tri-stated when a reset condition becomes active, even if the clock is not running.
Output from the inverting Oscillator amplifier. Home – IC Supply – Link. Atmel ATmega is a powerful microcontroller that provides a highly flexible and cost.
