SM1124 Series
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.
FEATURES
s Maximum of 16 tune selections (with up to 512
steps)
s Level hold playback mode
s External reference clock input. The frequency can
be selected from the following 12 settings.
• Playback frequency of each song varies (8
frequencies)
- 32.768 kHz system: 32.768 and 65.536 kHz
- 37.5 kHz system: 37.5 and 75.0 kHz
- 38.4 kHz system: 38.4 and 76.8 kHz
- 48.0 kHz system: 48.0 and 96.0 kHz
• Playback frequency of all songs is fixed (4
frequencies)
- 32.768 kHz system: 131.072 kHz
- 37.5 kHz system: 150.0 kHz
- 38.4 kHz system: 153.6 kHz
- 48.0 kHz system: 192.0 kHz
s 2-pin serial data tune selection
s Power save function
s External clock gating in non-play mode.
s 2.4 to 3.6 V supply voltage
s 8-pin plastic SOP package
s Molybdenum-gate CMOS process
