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

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.)

Cautions about operation!
•
Electrical properties presented on the data sheet for the mask ROM and ZTAT
TM
versions will surely
and sufficiently satisfy the standard values. However, real capabilities, operation margin, noise margin,
and other properties may vary depending on differences of manufacturing processes, internal wiring
patterns, etc. Therefore, it is requested for users to carry out an evaluation test for each product on an
actual system under the same conditions to see its operation.
•
After power supply has been connected, the values for the memory register, data and stack areas will be
undefined. Initialize prior to use.
