The Port B pins are tri-stated when a reset condition becomes active, even if the clockis not running.Depending on the clock selection fuse settings, PB6 can be used as input to the internal clockoperating circuit.The various special features of Port B are elaborated in “Alternate Functions of Port B” on page69.1.1.6Port C (PC7, PC5:0)Port C is a 8-bit bi-directional I/O port with internal pull-up resistors (selected for each bit).
Peripheral Features– One 8-bit Timer/Counter with Separate Prescaler and Compare Mode– One 16-bit Timer/Counter with Prescaler, and Compare and Capture Modes– 6- or 8-channel 10-bit ADC– Master/Slave SPI Serial Interface– Byte-oriented 2-wire Serial Interface (Philips I2C Compatible)– Programmable Watchdog Timer with Separate On-Chip Oscillator– On-Chip Analog Comparator– Interrupt and Wake-up on Pin Change•
High Endurance Non-volatile Memory Segments– 4K/8K Bytes of In-System Self-Programmable Flash Program Memory– 64/64 Bytes EEPROM– 256/512 Bytes Internal SRAM– Write/Erase Cycles: 10,000 Flash/100,000 EEPROM– Data Retention: 20 years at 85°C / 100 years at 25°C– Programming Lock for Software Security•
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.
