ATtiny88 Automotive 8-bit AVR Microcontroller with 8K Bytes In-System Programmable Flash DATASHEET Features High performance, low power AVR 8-Bit microcontroller Advanced RISC architecture 123 powerful instructions most single clock cycle e...
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
minimum pulse length is given in Table 22-3 on page 209. Shorter pulses are not guaranteed togenerate a reset.The various special features of Port C are elaborated in “Alternate Functions of Port C” on page72.1.1.8Port D (PD7:0)Port D is an 8-bit bi-directional I/O port with internal pull-up resistors (selected for each bit).

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.
