ThePD[7:4] output buffers have symmetrical drive characteristics with both sink and source capabil-ities, while the PD[3:0] output buffers have high sink capabilities. As inputs, Port D pins that areexternally pulled low will source current if the pull-up resistors are activated. The Port D pins aretri-stated when a reset condition becomes active, even if the clock is not running.The various special features of Port D are elaborated in “Alternate Functions of Port D” on page75.
1.1Pin Descriptions1.1.1VCCDigital supply voltage.1.1.2AVCCAVCC is the supply voltage pin for the A/D converter and a selection of I/O pins. This pin shouldbe externally connected to VCC even if the ADC is not used. If the ADC is used, it is recom-mended this pin is connected to VCC through a low-pass filter, as described in “Analog NoiseCanceling Techniques” on page 172.The following pins receive their supply voltage from AVCC: PC7, PC[5:0] and (in 32-lead pack-ages) PA[1:0].
The ATtiny48/88 is a low-power CMOS 8-bit microcontroller based on the AVR enhanced RISCarchitecture. By executing powerful instructions in a single clock cycle, the ATtiny48/88 achievesthroughputs approaching 1 MIPS per MHz allowing the system designer to optimize power con-sumption versus processing speed.
