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
• Mask ROM : 8096 words x 8 bits
• RAM (including the stack area) : 256 words x 4 bits
• I/O port
  Input-output port : 8 ports x 4 bits
  Input port : 1 port x 4 bits
4 bits are for input ports having a latch; the other 32 bits are for input/output ports that allow bit manipulation

                                  12-bit programmable timer
                                  8-bit high-speed programmable timer/event counter
• Built-in 8-bit serial I/O register (with 3-bit counter)
• Five interrupts with five priority levels (4 internal, 1 external)
• 32 stack levels (in RAM)
• Power down features
• Minimum instruction execution time : 1.0 ms @ 4.0 MHz clock
• Instruction systems suitable for control
• Fully static operation
• Low power consumption
• Single 5 V power supply
