DESCRIPTION
The M37735EHLXXXHP 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.
Its strong points are the low power dissipation, the low supply voltage
and the small package.
The M37735EHLXXXHP has the same function as the
M37735MHLXXXHP except that the built-in ROM is PROM. (Refer
to the basic function blocks description.)
