General description
The ATmega48A/PA/88A/PA/168A/PA/328/P provides the following features: 4K/8Kbytes of In-SystemProgrammable Flash with Read-While-Write capabilities, 256/512/512/1Kbytes EEPROM, 512/1K/1K/2KbytesSRAM, 23 general purpose I/O lines, 32 general purpose working registers, three flexible Timer/Counters withcompare modes, internal and external interrupts, a serial programmable USART, a byte-oriented 2-wire SerialInterface, an SPI serial port, a 6-channel 10-bit ADC (8 channels in TQFP and VQFN packages), aprogrammable Watchdog Timer with internal Oscillator, and five software selectable power saving modes. TheIdle mode stops the CPU while allowing the SRAM, Timer/Counters, USART, 2-wire Serial Interface, SPI port,and interrupt system to continue functioning. The Power-down mode saves the register contents but freezes theOscillator, disabling all other chip functions until the next interrupt or hardware reset. In Power-save mode, theasynchronous timer continues to run, allowing the user to maintain a timer base while the rest of the device issleeping. The ADC Noise Reduction mode stops the CPU and all I/O modules except asynchronous timer andADC, to minimize switching noise during ADC conversions. In Standby mode, the crystal/resonator Oscillator isrunning while the rest of the device is sleeping. This allows very fast start-up combined with low powerconsumption.
