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.

To all our customers
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.

HD404328 Series
Rev. 6.0
Sept. 1998
Description
The HD404328 Series is an HMCS400-Series microcomputer designed to increase program productivity
and also to incorporate large-capacity memory. Each microcomputer has an LCD controller/driver, A/D
converter, and zero-crossing detection circuit. Each also has a 32.768-kHz oscillator and low-power
dissipation modes.
The HD404328 Series includes eight chips: the HD404324 and HD404324U with 4-kword ROM; the
HD404326 and HD404326U with 6-kword ROM; the HD404328 and HD404328U with 8-kword ROM;
the HD4074329 and HD4074329U with 16-kword PROM. The HD404324U, HD404326U, HD404328U
and HD4074329U are designed to reduce current dissipation in subactive mode and watch mode.
The HD4074329 and HD4074329U, which include PROM, are ZTAT
TM
microcomputers that can
dramatically shorten system development periods and smooth the process from debugging to mass
production. (The PROM program specifications are the same as for the 27256.)
