Description
The HD404369 Series is a 4-bit HMCS400-Series microcomputer designed to increase program productivity and also incorporate large-capacity memory. Each microcomputer has an A/D converter, input capture timer, 32-kHz oscillator for clock, and four low-power dissipation modes.

Features
• 512-digit × 4-bit RAM
• 54 I/O pins
    ― One input-only pin
    ― 53 input/output pins: 8 pins are intermediate-voltage NMOS open drain with high-current pins (15 mA, max.)
• On-chip A/D converter (8-bit × 12-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
    ― Subclock: 32.768-kHz crystal oscillator
• Seven interrupt sources
    ― Two by external sources
    ― Three by timers
    ― One by A/D converter
    ― One by serial interface
• Four low-power dissipation modes
    ― Standby mode
    ― Stop mode
    ― Watch mode
    ― Subactive mode
• Instruction cycle time
