M37735S4LHP
16-BIT CMOS MICROCOMPUTER
DESCRIPTION
The M37735S4LHP is a microcomputer using the 7700 Family core.
This 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 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.
