DESCRIPTION
The M37733EHBXXXFP 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 M37733EHBXXXFP has the same function as the
M37733MHBXXXFP except that the built-in ROM is PROM. (Refer
to the basic function blocks description.) For program development,
the M37733EHBFS with erasable ROM that is housed in a windowed
ceramic LCC is also provided.
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).
FEATURES
