2. FEATURES
• Operating voltage range : 2.5V~5.5V
• Operating temperature range: -40°C~85°C
• Operating frequency rang (base on 2 clocks ):
* Crystal mode: DC~20MHz at 5V, DC~8MHz at 3V, DC~4MHz at 2.5V.
* ERC mode: DC~4MHz at 5V, DC~4MHz at 3V, DC~4MHz at 2.5V.
• Low power consumption:
* Less then 2 mA at 5V/4MHz
* Typically 20 µA at 3V/32KHz
* Typically 1 µA during sleep mode
• 1K × 13 bits on chip ROM

• 48× 8 bits on chip registers (SRAM, general purpose register)
• 2 bi-directional I/O ports
• 5 level stacks for subroutine nesting
• 8-bit real time clock/counter (TCC) with selective signal sources, trigger edges, and overflow interrupt
• Two clocks per instruction cycle
• Power down (SLEEP) mode
• Three available interruptions
* TCC overflow interrupt
* Input-port status changed interrupt (wake up from sleep mode)
* External interrupt
• Programmable free running watchdog timer
• 8 programmable pull-high pins
