10 / 102 page EM78P341N/342N/343N 8-Bit Microprocessor with OTP ROM 4 • Product Specification (V1.0) 12.01.2006 (This specification is subject to change without further notice) 5 Pin Description 5.1 EM78P341NP/M Symbol Pin No. Type Function P50~P55 1~3, 12~14 I/O 6-bit General purpose input/output pins Pull-high/pull-down Wake up from sleep mode when the pin status changes Default value at power-on reset P60, P61 66, 67 6~9 I/O 4-bit General purpose input/output pins Open drain Default value at power-on reset P70~P71 11, 4 I/O 2-bit General purpose input/output pins Default value at power-on reset /INT 6 I External interrupt pin triggered by a falling or a rising edge. Defined by CONT <7> ADC0~ADC6 1, 2, 9 11~14 I 7-bit Analog-to-Digital Converter Defined by ADCON (R9)<1:0> VREF 3 I External reference voltage for ADC Defined by ADCON (R9) <7>. /RESET 4 I General-purpose Input only If it remains at logic low, the device will be reset Wake-up from sleep mode when pin status changes Voltage on /RESET must not exceed Vdd during normal mode TCC, TCCA 3, 7 I External Counter input TCC defined by CONT<5> TCCA defined by IOC80 <1> OSCI 12 I Crystal type: Crystal input terminal or external clock input pin RC type: RC oscillator input pin OSCO 11 O Crystal type: Output terminal for crystal oscillator or external clock input pin. RC type: Clock output with a duration of one instruction cycle time. The prescaler is determined by the CONT register. External clock signal input. IR OUT 13 O IR mode output pin. Driving current = 10mA when the output voltage drops to Vdd-0.5V at Vdd = 5V Sinking current = 15mA when the output voltage drops to GND+0.5V at Vdd = 5V VDD 10 – Power supply VSS 5 – Ground |
