MSM80C154S/83C154S
Previous version: Nov. 1996
Semiconductor
MSM80C154S/83C154S
GENERAL DESCRIPTION
The MSM80C154S/MSM83C154S, designed for the high speed version of the existing
MSM80C154/MSM83C154, is a higher performance 8-bit microcontroller providing low-power
consumption.
The MSM80C154S/MSM83C154S covers the functions and operating range of the existing
MSM80C154/83C154/80C51F/80C31F.
The MSM80C154S is identical to the MSM83C154S except it does not contain the internal
program memory (ROM).

ports with floating or active status
The software power-down stet mode is termi-
nated by interrupt signal enabling execution from
the interrupted address.
