Document Outline

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.

HD404054 Series/HD404094 Series
Rev. 6.0
Sept. 1998
Description
The HD404054 Series and HD404094 Series are HMCS400-series microcomputers designed to increase
program productivity with large-capacity memory. Each microcomputer has three timers, one serial
interface, comparator, input capture circuit.
The HD404054 Series includes three chips: the HD404052 with 2-kword ROM; the HD404054 with 4-
kword ROM; and the HD4074054 with 4-kword PROM (ZTAT
TM
version). Also, the HD404094 Series
includes three chips: the HD404092 with 2-kword ROM; the HD404094 with 4-kword ROM; and the
HD4074094 with 4-kword PROM (ZTAT
TM
version).
The HD4074054 and HD4074094 are PROM version (ZTAT
TM
microcomputers). Program can be written
to the PROM by a PROM writer, which can dramatically shorten system development periods and smooth
the process from debugging to mass production. (The ZTAT
TM
version is 27256-compatible.)
