E2E1034 -27-Y4 ¡ Semiconductor MSM82C43 ¡ Semiconductor INPUT/OUTPUT PORT EXPANDER This version: Jan. 1998 MSM82C43 Previous version: Nov. 1996 GENERAL DESCRIPTION The MSM82C43 is an input/output port expander device based on CMOS technology and designed to operate at low power consumption levels. In systems employing the MSM80C48/49 8–bit single chip microcomputers, 4–bit data can be expanded by dividing between four I/O lines by executing the MOVDA, Pp, A and ORLDPp, A instructions. FEATURES • CMOS technology for low power consumption • 2.5 to 6 V single power supply (dependent on MSM80C48/49 operating frequency.
