I/O and Packages– 24 Programmable I/O Lines:• 28-pin PDIP• 28-pad QFN– 28 Programmable I/O Lines:• 32-lead TQFP• 32-pad QFN• 32-ball UFBGA•Operating Voltage:–1.8–5.5V•Temperature Range:–-40°C to +85°C•Speed Grade:–0–4 MHz @ 1.8 – 5.5V–0 – 8 MHz @ 2.7 – 5.5V–0 – 12 MHz @ 4.5 – 5.5V•Low Power Consumption– Active Mode: 1 MHz, 1.8V: 240 μA– Power-Down Mode: 0.1 μA at 1.8V 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. ThePC7 and PC[5:0] output buffers have symmetrical drive characteristics with both sink and sourcecapability. As inputs, Port C pins that are externally pulled low will source current if the pull-upresistors are activated. The Port C pins are tri-stated when a reset condition becomes active,even if the clock is not running.1.1.7PC6/RESETIf the RSTDISBL Fuse is programmed, PC6 is used as an I/O pin. Note that the electrical char-acteristics of PC6 differ from those of the other pins of Port C.If the RSTDISBL Fuse is unprogrammed, PC6 is used as a reset input. A low level on this pin forlonger than the minimum pulse width will generate a reset, even if the clock is not running. The 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.
