2. FEATURES

• 14-lead packages : EM78P153E

• Operating voltage range : 2.3V~5.5V

• Available in temperature range: 0°C~70°C

• Operating frequency rang (base on 2 clocks ):

* Crystal mode: DC~20MHz at 5V, DC~8MHz at 3V, DC~4MHz at 2.3V.

* ERC mode: DC~4MHz at 5V, DC~4MHz at 3V, DC~4MHz at 2.3V.

• Low power consumption:

* less then 1.5mA at 5V/4MHz

* typical of 15 µA, at 3V/32KHz

* typical of 1 µA, during the sleep mode

• 512 × 13 bits on chip ROM

• Three built-in calibrated IRC oscillators

• Programmable prescaler of oscillator set-up time

• On-board bit by bit programming

• One security register to prevent the code in the OTP memory from intruding

• One configuration register to match the user’s requirements

• 32× 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

• Power down mode (SLEEP mode)

• Three available interruptions

* TCC overflow interrupt

* Input-port status changed interrupt (wake up from the sleep mode)

* External interrupt

• Programmable free running watchdog timer

• 7 programmable pull-high I/O pins

• 7 programmable open-drain I/O pins

• 6 programmable pull-down I/O pins

• Two clocks per instruction cycle

• 99.9% single instruction cycle commands
