• CPU configuration

• 4Kx13 bits on-chip ROM
• 144x8 bits on-chip registers (SRAM)
• 8 level stacks for subroutine nesting
• Less than 2.2 Ma at 5V/4MHz
• Typically 15 Ua, at 3V/32kHz
• Typically 1 Ua, during sleep mode

• I/O port configuration

• 3 bi-directional I/O ports
• Wake-up port : P6
• 8 Programmable pull-down I/O pins
• 8 programmable pull-high I/O pins
• 8 programmable open-drain I/O pins
• External interrupt : P50

• Operating voltage range:

• 2.3V~5.5V at 0°C~70°C (commercial)
• 2.5V~5.5V at -40°C~85°C (industrial)

• Operating frequency range (base on 2 clocks):

• Crystal mode: DC ~ 20 MHz, 5V; DC ~ 8MHz, 3V
• ERC mode: DC ~ 16MHz, 5V; DC ~ 4MHz, 3V
• IRC mode: 4MHz at 2.3V~5.5V

• All these four main frequencies can be trimmed by programming with four calibrated bits in the ICE418N Simulator. OTP is auto trimmed by ELAN Writer.
• Fast set-up time requires only 2ms in high Crystal and 32 CLKS in IRC mode from wake up to operating mode.
• Peripheral configuration

• 8-bit real time clock/counter (TCC) with selective signal sources, trigger edges, and overflow interrupt
• 8-bit multi-channel Analog-to-Digital Converter with 12-bit resolution in Vref mode
• Three Pulse Width Modulation (PWM ) with 10-bit resolution
• One pair of comparator (Can be set as an OP)
• Power-down (Sleep) mode

• Six available interrupts

• TCC overflow interrupt
• Input-port status changed interrupt (wake up from sleep mode)
• External interrupt
• ADC completion interrupt
• PWM period match completion
• Comparator high/low interrupt

• Programmable free running watchdog timer
• Power-on voltage detector provided (2.0V+0.1V)
• Package types:?

• 18 pin DIP 300mil : EM78P418ND18J/S
• 18 pin SOP 300mil : EM78P418NSO18J/S
• 20 pin DIP 300mil : EM78P418ND20J/S
