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...
Special Microcontroller Features– debugWIRE On-Chip Debug System– In-System Programmable via SPI Port– Power-On Reset and Programmable Brown-Out Detection– Internal Calibrated Oscillator– External and Internal Interrupt Sources– Three Sleep Modes: Idle, ADC Noise Reduction and Power-Down– On-Chip Temperature Sensor•
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.
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•
Features•High Performance, Low Power AVR® 8-Bit Microcontroller•Advanced RISC Architecture– 123 Powerful Instructions – Most Single Clock Cycle Execution– 32 x 8 General Purpose Working Registers– Fully Static Operation•
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.
