ATmega 8-bit AVR Microcontrollers
- Atmel ATMEGA48A-AU, The high-performance Atmel 8-bit AVR RISC-based microcontroller combines 4KB ISP flash memory, 256-Byte EEPROM, 512-Byte SRAM, 23 general purpose I/O lines, 32 general purpose working registers, three flexible timer/counters with compare modes, internal & external interrupts, serial programmable USART, a byte-oriented 2-wire serial interface, SPI serial port, 6-channel 10-bit A/D converter (8-channels in TQFP & QFN/MLF packages), programmable watchdog timer with internal oscillator, & five software selectable power saving modes. The device operates between 1.8 & 5.5V. By executing powerful instructions in a single clock cycle, the device achieves throughputs approaching 1 MIPS per MHz, balancing power consumption & processing speed.
