Voltage Range
2.0 V to 3.6 V
2.0 V to 3.6 V
2.0 V to 3.6 V
• Low power consumption—40 mW (typical)
• Three standby modes
– STOP—2 mA (typical)
– HALT—0.8 mA (typical)
– Low voltage
• Special architecture to automate both generation and reception of complex
pulses or signals:
– One programmable 8-bit counter/timer with two capture registers and two
load registers
– One programmable 16-bit counter/timer with one 16-bit capture register
pair and one 16-bit load register pair
– Programmable input glitch filter for pulse reception
• Five priority interrupts
– Three external
– Two assigned to counter/timers
• Low voltage protection
• Programmable watch-dog/power-on reset circuits
• Two independent comparators with programmable interrupt polarity
• Mask-selectable pull-up transistor on Ports 0, 2, and 3
