MC68704P2 - Motorola

MC68704P2 HMOS Microcomputer

Vec AND VSS Power is supplied to the microcomputer using these two pins. Vee is + 5 volts (± 0.5 V) power, and VSS is ground. IRQ This pin provides the capability for asynchronously applying an external interrupt to the microcomputer. II EXTAL AND XTAL These pins provide control input for the on-chip clock oscillator circuit. A crystal, a resistor/capaci.
