Regarding the change of names mentioned in the document, such as Hitachi
Electric and Hitachi XX, to Renesas Technology Corp.
The semiconductor operations of Mitsubishi Electric and Hitachi were transferred to Renesas
Technology Corporation on April 1st 2003. These operations include microcomputer, logic, analog
and discrete devices, and memory chips other than DRAMs (flash memory, SRAMs etc.)
Accordingly, although Hitachi, Hitachi, Ltd., Hitachi Semiconductors, and other Hitachi brand
names are mentioned in the document, these names have in fact all been changed to Renesas
Technology Corp. Thank you for your understanding. Except for our corporate trademark, logo and
corporate statement, no changes whatsoever have been made to the contents of the document, and
these changes do not constitute any alteration to the contents of the document itself.

Cautions
Keep safety first in your circuit designs!
1.
Renesas Technology Corporation puts the maximum effort into making semiconductor products better and more reliable, but
there is always the possibility that trouble may occur with them. Trouble with semiconductors may lead to personal injury, fire
or property damage.
Remember to give due consideration to safety when making your circuit designs, with appropriate measures such as (i)
placement of substitutive, auxiliary circuits, (ii) use of nonflammable material or (iii) prevention against any malfunction or
mishap.

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 ZTATTM 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.
Memory register, data area, and stack area values are unstable immediately after power is turned on.
They must be initialized before use.
