MITSUBISHI MICROCOMPUTERS
M37733EHBXXXFP
M37733EHBFS
PROM VERSION OF M37733MHBXXXFP
DESCRIPTION
●Single power supply ...................................................... 5 V ± 10%
●Low power dissipation (at 25 MHz frequency)
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.
............................................47.5 mW (Typ.)
●Interrupts ............................................................ 19 types, 7 levels
●Multiple-function 16-bit timer ................................................. 5 + 3
●Serial I/O (UART or clock synchronous) ..................................... 3
●10-bit A-D converter ............................................ 8-channel inputs
●Watchdog timer
●Programmable input/output
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.
(ports P0, P1, P2, P3, P4, P5, P6, P7, P8) ............................... 68
●Clock generating circuit ........................................ 2 circuits built-in
APPLICATION
Control devices for general commercial equipment such as office
automation, office equipment, and so on.
FEATURES
●Number of basic instructions .................................................. 103
Control devices for general industrial equipment such as
communication equipment, and so on.
●Memory size
PROM .............................................124 Kbytes
RAM ................................................ 3968 bytes
Note. Do not use the windowed EPROM version for mass production,
because it is a tool for program development (for evaluation).
●Instruction execution time
The fastest instruction at 25 MHz frequency ...................... 160 ns
