HD404889/HD404899/HD404878/

HD404868 Series

Low-Voltage AS Microcomputers with On-Chip LCD Circuit

ADE-202-075D (O)

Rev. 5.0

Feb. 2000

Description

The HD404889, HD404899, and HD404868 Series comprise low-voltage, 4-bit single-chip

microcomputers with a variety of on-chip supporting functions that include an LCD circuit, A/D converter,

multifunctional timers, and large-current I/O pins. These devices are suitable for system and display panel

control in a wide range of applications, including pagers, remote controllers, and home appliances equipped

with an LCD display.

The HD404878 Series comprises low-voltage, 4-bit single-chip microcomputers with no on-chip A/D

converter.

Each series is equipped with 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 HD4074889, HD4074899, and HD4074869 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.)
