Description
The SM1125-ASV-ET is an electronic component model in the IC Chips product category. It is a melody IC fabricated in NPC's Molybdenum-gate CMOS, designed for use in mobile telecommunications equipment. The IC has a programmable ROM that can store a maximum of 16 melodies.
Specifications and features
- Maximum of 16 melody selections (with up to 512 steps)
- Level hold playback mode
- External reference clock input versions and builtin RC oscillator versions available, set by masterslice option (RC oscillator versions require an external resistor and capacitor).
- 12 selectable clock frequencies (fixed for all melodies):
- External clock input versions (12 frequencies):
- 32.768kHz system: 32.768, 65.536 and 131.072kHz
- 37.5kHz system: 37.5, 75.0 and 150.0kHz
- 38.4kHz system: 38.4, 76.8 and 153.6kHz
