― One input-only pin

― 33 input/output pins: 4 pins are intermediate-voltage NMOS open drain with high-current pins (15 mA, max.)

? On-chip A/D converter (8-bit × 8-channel)

― Low power voltage 2.7 V to 6.0 V

? Three timers

― One event counter input

― One timer output

― One input capture timer

? Eight-bit clock-synchronous serial interface (1 channel)

? Alarm output

? Built-in oscillators

― Ceramic oscillator or crystal

― External clock drive is also possible

? Seven interrupt sources

― Two by external sources

― Three by timers

― One by A/D converter

― One by serial interface

? Two low-power dissipation modes

― Standby mode

― Stop mode

? Instruction cycle time

― 0.47 μs (fOSC = 8.5 MHz, 1/4 division ratio): HD40A4354, HD40A4356, HD40A4358, HD407A4359

― 0.8 μs (fOSC = 5 MHz, 1/4 division ratio): HD404354, HD404356, HD404358
