To all our customers
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.
Notes regarding these materials
1. These materials are intended as a reference to assist our customers in the selection of the Renesas
Technology Corporation product best suited to the customer's application; they do not convey any
license under any intellectual property rights, or any other rights, belonging to Renesas Technology
Corporation or a third party.
2. Renesas Technology Corporation assumes no responsibility for any damage, or infringement of any
third-party's rights, originating in the use of any product data, diagrams, charts, programs, algorithms, or
circuit application examples contained in these materials.

HD404639R Series
4-Bit Single-Chip Microcomputer
Rev. 6.0
Sept. 1998
Description
The HD404639R Series is a member of the HMCS400-series microcomputers designed to increase
program productivity with large-capacity memory. The HD404639R Series, completely compatible with
the HD404639 Series, reduces current dissipation in half and includes a high-speed version. Each
microcomputer has a high-precision dual-tone multi frequency (DTMF) generator, four timers, two serial
interfaces, voltage comparator, input capture circuit, 32-kHz oscillator for clock, and four low-power
dissipation modes.
The HD404639R Series includes 5 chips: the HD404638R and HD40A4638R with 8-kword ROM; the
HD404639R and HD40A4639R with 16-kword ROM; the HD407A4639R with 16-kword PROM.
HD40A4638R, HD40A4639R, HD407A4639R are high-speed versions (minimum instruction cycle time:
0.5 µs).
The HD407A4639R is a PROM version ZTATmicrocomputer. A 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 ZTATversion is 27256-compatible.)

Features
8,192-word × 10-bit ROM (HD404638R, HD40A4638R)
16,384-word × 10-bit ROM (HD404639R, HD40A4639R, HD407A4639R)
1,152-digit × 4-bit RAM
61 I/O pins and 7 dedicated input pins
12 high-current output pins: Eight 15-mA sinks (a maximum of 7 pins can be used at the same time)
and four 10-mA sources
Four timer/counters
Eight-bit input capture circuit
Three timer outputs (including two PWM outputs)
Two event counter inputs (including one double-edge function)
Two clock-synchronous 8-bit serial interfaces
