Nuvoton Technology Introduces ARM-Based Audio System SOC ISD9160
21ic News Nuvoton Technology introduces the ChipCorder® ISD9160 system single-chip (SOC) with a 32-bit ARM® CortexTM-M0 microcontroller core. The design concept of the ISD9160 is optimized for demanding industrial applications (eg portable medical equipment, security systems and mass transit) and consumer designs (including: wireless audio, home appliances, toys and novelty products). Low-power recording and playback functions such as capacitive button sensing.

The ISD9160 features a Cortex-M0 microcontroller running at up to 50MHz, sophisticated power management features, embedded flash and SRAM memory, real-time frequency (RTC) controllers, and general purpose IO (GPIO), enabling designers to develop simple Systems and products that are reliable and easy to develop audio recording and playback functions. As the newest force in the new TangCang ChipCorder® product line, the ISD9160 also simplifies the design time of the product and reduces the cost of the bill of materials. The highly integrated architecture of the chip itself eliminates the need for designers to use many different Peripheral chip.
The ISD9160 can also play brand messages on a variety of consumer products, enabling manufacturers to use their own products that can play high-quality voice-messages and load corporate audio content, making their products different from other products on the market.
Farid Noory, Senior Product Marketing Manager at Nuvoton, said: "The ChipCorder® ISD9160's ARM core and highly integrated analog features make it ideal for recording and playback, capacitive button sensing and other demanding audio applications. "It's structured to ensure that manufacturers can design cost-effective and powerful audio products that use full-featured SoCs to enter other industrial and consumer market segments."
The ISD9160 integrates multiple voice interfaces such as a microphone, speaker driver and I 2S, as well as eight GPIOs for capacitive sensing and analog functions. In addition, five power-saving modes allow the device to operate at different operating voltages. Make it suitable for portable/battery-powered products. Because the ISD9160 takes advantage of the Cortex-M0 processing engine, it can also incorporate features such as speech recognition, voice prompts, and long-term recording/playing that use a lot of CPU resources.
The ARM Cortex-M0 core used in the ISD9160 provides 32-bit performance and consumes less power, but at a price comparable to that of an 8-bit microcontroller. Designers can use their 32-bit architecture to develop sophisticated algorithms such as speech recognition, text-to-speech (TTS) and wireless audio, all of which must have used digital signal processors (DSPs) and/or other high-end ARMs in the past. Device.
Features of ISD9160:
