HD404449 Series
Rev. 6.0
Sept. 1998
mDescription
.coThe HD404449 Series is a HMCS400-series microcomputer designed to increase program productivity
with large-capacity memory. Each microcomputer has four timers, two serial interfaces, A/D converter,
input capture circuit, 32-kHz oscillator for clock, and four low-power dissipation modes.
UThe HD404449 Series includes three chips: the HD404448 with 8-kword ROM; the HD404449 with 16-
t4kword ROM; and HD4074449 with 16-kword PROM (ZTAT™ version).
eThe HD4074449 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
edebugging to mass production. (The ZTAT™ version is 27256-compatible.)
hZTAT™: Zero Turn Around Time ZTAT is a trademark of Hitachi Ltd.
