The
high-performance,
low-power
Microchip
8-bit
AVR®
RISC-based
microcontroller
combines
16
KB
ISP
flash
memory
with
read-while-write
capabilities,
512B
EEPROM,
512B
SRAM,
22
general
purpose
I/O
lines,
32
general
purpose
working
registers,
two
flexible
timer/counters
with
compare
modes
and
PWM,
USART,
programmable
watchdog
timer
with
internal
oscillator,
SPI
serial
port,
debugWIRE
interface
for
on-chip
debugging
and
programming,
and
five
software
selectable
power
saving
modes.
The
device
operates
between
2.7-5.5
volts.By
executing
powerful
instructions
in
a
single
clock
cycle,
the
device
achieves
throughputs
approaching
one
MIPS
per
MHz,
balancing
power
consumption
and
processing
speed.
