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
μ
s).
The HD407A4639R is a PROM version ZTAT
microcomputer. 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 ZTAT
version is 27256-compatible.)
