M37735EHBFS
PROM VERSION OF M37735MHBXXXFP
DESCRIPTION
The M37735EHBXXXFP is a single-chip microcomputer using the
7700 Family core. This single-chip microcomputer has a CPU and a
bus interface unit. The CPU is a 16-bit parallel processor that can be
an 8-bit parallel processor, and the bus interface unit enhances the
memory access efficiency to execute instructions fast. This
microcomputer also includes a 32 kHz oscillation circuit, in addition
to the PROM, RAM, multiple-function timers, serial I/O, A-D converter,
and so on.
The M37735EHBXXXFP has the same function as the
M37735MHBXXXFP except that the built-in ROM is PROM. For
program development, the M37735EHBFS with erasable ROM that
is housed in a windowed ceramic LCC is also provided. (Refer to the
basic function blocks description.)

APPLICATION
Control devices for general commercial equipment such as office
automation, office equipment, and so on.
Control devices for general industrial equipment such as
communication equipment, and so on.
Note. Do not use the windowed EPROM version for mass production,
because it is a tool for program development (for evaluation).
