Description
The HD404374, HD404384, and HD404389 Series comprise low-voltage, 4-bit single-chip
microcomputers equipped with four 10-bit A/D converter channels, a serial interface, and large-current I/O
pins. These devices are suitable for use in applications requiring high resolution A/D converter control,
such as battery chargers.
The HD404082 and HD404084 series offer less advanced features than the HD404384 series. They are 4-
bit microcomputers that support low-voltage operation for backward software compatibility.
HD404374 Series microcomputers have a 32.768 kHz sub-resonator for realtime clock use, providing a
time counting facility, and a variety of low-power modes to reduce current drain.
The HD407A4374, HD407A4384, HD407A4389, HD407C4374, HD407C4384, and HD407C4389 are
ZTAT^TM microcomputers with on-chip PROM that drastically shortens development time and ensures a
smooth transition from debugging to mass production. (The PROM programming specifications are the
same as for the 27256 type.)
