H8/3753, H8/3754
The H8/3754 Series microcomputers are
8-bit single chip microcomputers that can
directly drive vacuum fluorescent displays
(VFD).
The H8/3753 and H8/3754 microcomputers
integrate, around an H8/300L CPU core, a
rich set of peripheral functions, including
24 and 32 kbytes of ROM, 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 H8/3754 Series includes ZTAT™ (zero turn around time) versions of the
H8/3726 that allow users to freely write programs to the on-chip PROM.
