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.

HD404629R Series
AS Microcomputer Incorporating a DTMF Generator Circuit
ADE-202-048D
Rev.5.0
Sept. 1999
Description
The HD404629R Series is part of the HMCS400-Series microcomputers designed to increase program
productivity and also incorporate large-capacity memory. Each microcomputer has a high precision dual-
tone multifrequency (DTMF) generator, LCD controller/driver, A/D converter, input capture circuit, 32-
kHz oscillator for clock, and four low-power dissipation modes.
The HD404629R Series includes four chips: the HD404628R with 8-kword ROM; the HD4046212R with
12-kword ROM; the HD404629R with 16-kword ROM; the HD4074629 with 16-kword PROM.
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.
Features
1,876-digit × 4-bit RAM
44 I/O pins, including 10 high-current pins (15 mA, max.) and 20 pins multiplexed with LCD segment
pins
Four timer/counters
w8w-wb.iDt aintapSuhteceat4pUtu.creomcircuit
Three timer outputs (including two PWM out-puts)
Two event counter inputs (including one double-edge function)
Clock-synchronous 8-bit serial interface
A/D converter (4 channels × 8 bits)
LCD controller/driver (52 segments × 4 commons)
On-chip DTMF generator
Built-in oscillators
Main clock: 4-MHz ceramic (an external clock is also possible)
Subclock: 32.768-kHz crystal
Eleven interrupt sources
Five by external sources, including three double-edge functions
Six by internal sources
Subroutine stack up to 16 levels, including interrupts
