§ CMOS Technology:

+ Wide operating voltage range:

3 2.0V to 6.0V

+ Low power consumption:

3 < 2 mA typical @ 5V, 4 MHz

3 60 µA typical @ 2V, 32 kHz

3 26 µA typical standby current @ 2V

§ High Performance RISC CPU Features:

+ 1K x 14 EEPROM program memory

+ Only 35 single word instructions to learn

+ All instructions single cycle (400 ns @ 10

MHz) except for program branches which

are two-cycle

+ Eight-level deep hardware stack
