MC68HC04J2 - Motorola

MC68HC04J2 8-Bit Microcontroller

VOD AND VSS Power is supplied to the MCU using these two pins. VDD is power, and VSS is ground. IRQ This pin provides the capability for asynchronously ap- plying an external interrupt to the MCU. A pull-up resistor on this pin is a manufacturing mask option. EXTAl AND XTAl These pins provide control input for the on-chip clock oscillator circuit. A crystal,.
