M37735MHLXXXHP
SINGLE-CHIP 16-BIT CMOS MICROCOMPUTER
DESCRIPTION
The M37735MHLXXXHP 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.
