Car Audio/Voice Prompt

Voice prompt warnings are components used in today's high-end luxury cars. Whether they are dashboard warnings, such as speeding, oil, water level gauges, temperature/heat, tire pressure warnings or pedestrian warning sounds for electric vehicles, they all use shared sound chips.

Nuvoton has designed many highly integrated single-chip solutions that can be used as integrated parts for future automobiles. Although the cost of ISD15D00/ISD15C00 is low, it is the best audio quality recording and playback device in its class, allowing everyday low-end cars to have audio-level sounds or voice prompts. By providing smooth communication to the SPI port of the automotive network system, system integration becomes extremely simple. ISD15D00 uses external SPI flash memory audio with built-in regulator PWM speaker driver, analog digital input and output, suitable for multi-language storage devices and audio playback of up to 64 minutes. The ISD15D00 voice macro is designed for situations where, for example, the language of the external flash memory changes but the application software does not.

Nuvoton's digital ChipCorder product ISD15D00/ISD15C00 is: 

• AEC-Q100 grade automotive standards
• Built-in thermal alarm provides overheat protection
• Best audio quality in its class
• Long-term product life cycle, capable of recording excellent audio tracks, providing a 5-10 year manufacturing cycle for cars.
