MITSUBISHI MICROCOMPUTERS
M37733EHLXXXHP
PRELIMINARY
Notice: This is not a final specification.
Some parametric limits are subject to change.
PROM VERSION OF M37733MHLXXXHP
DESCRIPTION
●Single power supply ...................................................... 2.7–5.5 V
●Low power dissipation (At 3 V supply voltage, 12 MHz frequency)
............................................ 9 mW (Typ.)
The M37733EHLXXXHP 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.
●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
Its strong points are the low power dissipation, the low supply voltage,
and the small package.
(ports P0, P1, P2, P3, P4, P5, P6, P7, P8) ............................... 68
●Clock generating circuit ........................................ 2 circuits built-in
●Small package ..................... 80-pin plastic molded fine-pitch QFP
(0.5 mm lead pitch)
The M37733EHLXXXHP has the same function as the
M37733MHLXXXHP except that the built-in ROM is PROM. (Refer
to the basic function blocks description.)
