Speech and Sound Playback ICs
ML2280x Series - Voice Synthesis LSI Equipped with P2ROM™ |
Though demands to include voice guidance into consumer electronics and home digital appliances have been increasing, because conventional products were mask ROM equipped, the time from placing an order to receiving delivery took long. Oki's ML2280X Series solves this problem as it stocks the P2ROM voice synthesis LSIs, which have completed the wafer production up to the packaging assembly. Once a customer orders a product, Oki writes the voice data into the chip, conducts testing and ships the product to the customer. Compared to mask ROM voice synthesis LSIs, Oki can now reduce the time from order to delivery by one-third. Update: new low cost pin-compatible OTP versions are available called ML22P80x series and ML22P16 including programming tools (parawriters) to create small pre-production volumes for full flexibility in your application |
ML2280X Series, a voice synthesis LSI equipped with P2ROM™ (Production Programmed ROM) that can be delivered in volume in a minimum of two weeks after order. Oki succeeded in reducing the packaging size to half compared to the previous product, ML2216, which was launched in February 2006. Oki now offers P2ROM-equipped products as a series.
