SM1124 Series
NIPPON PRECISION CIRCUITS—1
NIPPON PRECISION CIRCUITS INC.
Multimelody IC for Pagers
OVERVIEW
The SM1124 Series are melody pager multi-melody
ICs fabricated in NPC’s Molybdenum-gate CMOS.
A maximum of 16 tunes can be stored in
programmable ROM, and the Molybdenum-gate
CMOS process realizes small-sized packages and
low power dissipation.
