M37736MHLXXXHP
SINGLE-CHIP 16-BIT CMOS MICROCOMPUTER
DESCRIPTION
The M37736MHLXXXHP 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 ROM, RAM, multiple-function timers, serial I/O, A-D converter,
and so on.
Its strong points are the low power dissipation, the low supply voltage,
and the small package.
In the M37736MHLXXXHP, as the multiplex method of the external
bus, either of 2 types can be selected.
