- Instruction Cycle: 0.44 µs (4.5-MHz crystal oscillator used)
- Large array of on-chip peripheral hardware General-purpose input/output port, A/D converter, serial interface, timer, frequency counter, power-ON clear circuits.
- On-chip hardware for a PLL frequency synthesizer. Dual modulus pre-scaler, programmable divider, phase comparator, charge pump.
- Vector Interrupts: 17
- Supply Voltage: VDD = 4.5 to 5.5 V (during PLL operation) VDD = 3.5 to 5.5 V (during CPU operation, when the system clock is fX/2 or lower) VDD = 4.5 to 5.5 V (during CPU operation, when the system clock is fX) Th
