M6408-50

GENERAL DESCRIPTION

The MSM6408 microcontroller is a low-power, single-chip device implemented in complementary
metal-oxide semiconductor technology.
The MSM6408 is optimized for high-speed processing and complicated-control applications, in
which conventional microcontrollers are difficult to use.

FEATURES
