M6404A Overview
The MSM6404A microcontroller is a low-power device implemented in plementary metaloxide semiconductor technology. The MSM6404A is optimized for high-speed processing and plicated-control applications. The MSM6404VS is a CMOS 4-bit microcontroller that employs an external EPROM using a piggy-back package in place of the program memory (ROM) internal to the MSM6404A.
