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

• Three built-in counters : 12-bit time-base counter

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

• Package options:
