The H8/3724 Series microcomputers are
8-bit single chip microcomputers that can
directly drive vacuum fluorescent displays
(VFD).
The H8/3723, H8/3724, H8/3725, and
H8/3726 microcomputers integrate, around
an H8/300L CPU core, a rich set of
peripheral functions, including 24, 32, 40,
and 48 kbytes of ROM, 384, 512, 640, and
1024 bytes of RAM, a VFD (vacuum
fluorescent display) controller/driver,
timers, two serial communications interfaces, a 14-bit PWM, an A/D converter, and I/O
ports. Since these microcomputers include high breakdown voltage pins that can directly
drive VFD panels, they are particularly suited for use in applications that require VFD.
Additionally, the H8/3724 Series includes ZTAT™ (zero turn around time) versions of the
H8/3724 and H8/3726 that allow users to freely write programs to the on-chip PROM.
