SM1124 Product details

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
■ Maximum of 16 tune selections (with up to 512 steps)
■ Level hold playback mode
■ 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
■ 2-pin serial data tune selection
■ Power save function
■ External clock gating in non-play mode.
■ 2.4 to 3.6 V supply voltage
■ 8-pin plastic SOP package
■ Molybdenum-gate CMOS process
