Previous version: Nov. 1996
MSM80C48/49/50
MSM80C35/39/40
CMOS 8-Bit Microcontroller
GENERAL DESCRIPTION
The OKI MSM80C48/MSM80C49/MSM80C50 are 8-bit, low-power, high-performance micro-
controllers implemented in silicon-gate complementary metal-oxide semiconductor technology.
Integrated within these chips are 8K/16K/32K bits of mask program ROM, 512/1024/2048 bits
of data RAM, 27 I/O lines, built-in 8 bit timer/counter, and oscillator. Program memory and data
paths are byte wide. Eleven new instructions have been added to the NMOS version's instruction
set, thereby optimizing power down, port data transfer, decrement and port float functions.
Available in 40-pin plastic DIP (RS) or 44-pin plastic flat packages QFP (GSK).

Details of IC pin status as a result of executing the FLTT instruction are shown in above
Table.
Example 1 : Power-down mode accomplished by stopping oscillation.
m Can be set by execution of HLTS [82H] instruction.
Example 2 : Power-down mode accomplished by stopping the clock supply to the CPU
control circuit.
m Can be set by execution of HALT [01H] instruction.
Example 3 : Power-down mode by floating of P10-7, P20-7 and BP0-7, and subsequent
stopping of CPU oscillation.
m Can be set by first executing the FLT [A2H] instruction, followed by the
HLTS [82H] instruction.
Example 4 : Power-down mode by floating P10-7, P20-7 and BP0-7, and then stopping the
clock supply to the CPU control circuit.
m Can be set by first executing the FLT [A2H] instruction, and then the HALT
[01H] instruction.
Example 5 : Power-down mode by floating all output pins, followed by stopping oscillation.
m Can be set by first executing the FLTT [C2H] instruction followed by
execution of the HLTS [82H] instruction.
Example 6 : Power-down mode by floating all output pins, followed by stopping of the
clock supply to the CPU control circuit.
m Can be set by first executing the FLTT [C2H] instruction, followed by
execution of the HALT [01H] instruction. Connect the pull-up resistor or
pull-down resistor to port pin and fix the output port pin level to either 1or
0 when output port is set to floating.
