Description
The ATmega603/103 is a low-power CMOS 8-bit microcon-
troller based on the AVR enhanced RISC architecture. By
executing powerful instructions in a single clock cycle, the
ATmega603/103 achieves throughputs approaching 1
MIPS per MHz allowing the system designer to optimize
power consumption versus processing speed.
The AVR core is based on an enhanced RISC architecture
that combines a rich instruction set with 32 general purpose
working registers. All the 32 registers are directly con-
nected to the Arithmetic Logic Unit (ALU), allowing two
independent registers to be accessed in one single instruc-
tion executed in one clock cycle. The resulting architecture
is more code efficient while achieving throughputs up to ten
times faster than conventional CISC microcontrollers.
The ATmega603/103 provides the following features:
64K/128K bytes of In-system Programmable Flash, 2K/4K
bytes EEPROM, 4K bytes SRAM, 32 general purpose I/O
lines, 8 Input lines, 8 Output lines, 32 general purpose
working registers, 4 flexible timer/counters with compare
modes and PWM, UART, programmable Watchdog Timer
with internal oscillator, an SPI serial port and three software
selectable power saving modes. The Idle Mode stops the
CPU while allowing the SRAM, timer/counters, 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
2 ATmega603/L and ATmega103/L
