The
high-performance
Microchip
8-bit
AVR®
RISC-based
picoPower®
microcontroller
combines
8
KB
ISP
Flash
memory
with
read-while-write
capabilities,
512B
EEPROM,
1
KB
SRAM,
23
general
purpose
I/O
lines,
32
general
purpose
working
registers,
three
flexible
timer/counters
with
compare
modes,
internal
and
external
interrupts,
serial
programmable
USART,
a
byte-oriented
Two-Wire
serial
interface,
SPI
serial
port,
6-channel
10-bit
A/D
converter
(8-channels
in
TQFP
and
QFN/MLF
packages),
programmable
watchdog
timer
with
internal
oscillator,
and
five
software
selectable
power
saving
modes.
The
device
operates
between
1.8-5.5
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.
