Instruction Set Architecture

RISC

The Microchip ATmega48PA CMOS 8-bit microcontroller based on the AVR enhanced RISC architecture. It operates on 2.7V to 5.5V voltage range. The AVR core combines a rich instruction set with 32 general purpose working registers. It features 4Kbytes of in-system programmable flash with read-while-write capabilities, 256bytes EEPROM, 512 bytes SRAM, 23 general purpose I/O lines, 32 general purpose working registers, three flexible Timer/Counters with compare modes, internal and external interrupts, a serial programmable USART, a byte-oriented 2-wire serial interface, an SPI serial port, a 8-channel 10-bit ADC, a programmable watchdog timer with internal oscillator, and five software selectable power saving modes. The idle 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 the oscillator, disabling all other chip functions until the next interrupt or hardware reset.
