H8/3924, H8/3925, H8/3926, H8/3927
The H8/3927 Series microcomputers are
8-bit single chip microcomputers that
provide an on-chip D/A converter.
The H8/3924, H8/3925, H8/3926, and
H8/3927 microcomputers integrate, around
an H8/300L CPU core, a rich set of
peripheral functions, including 32, 40, 48,
and 60 kbytes of ROM, 1 kbyte of RAM, a
D/A converter, timers, a 14-bit PWM, two
serial communications interfaces, an A/D
converter, and I/O ports. These products
are particularly suited for use as the embedded microprocessor in applications that require
the control of analog signals.
Additionally, the H8/3927 Series includes a ZTAT™ (zero turn around time) version of the
H8/3927 that allows users to freely write programs to the on-chip PROM.
