HT2830 Up/Down Tone Generator Features * * * * Single power supply: 2.4V~3.3V Low standby current: 1A (Typ.) at VDD=3V Speaker or direct piezo application Sound output: one Main Tone plus two Fighting Sounds (1,2) * * * Two direct LED drive outputs (The flash rate depends on the sound speed) Option mode selection: normal mode or auto mode (bonding option) Minimum external components General Description The HT2830 is a CMOS LSI chip designed for use in sound effect products. It is a body structure including tone circuit, noise circuit, an updown counter, and other control logic to generate various sounds such as JET plane, motorcycle, helicopter, train, and so forth. Features from the customer's sound samples can be analyzed and programmed into an internal ROM by changing a mask layer during device fabrication. The HT2830 is suitable for various toy applications.
