Nuvoton Technology introduces the ChipCorder® ISD9160 system-on-chip (SOC) using the 32-bit ARM® Cortex ™ -M0 microcontroller core. The design concept of ISD9160 is to optimize the wide application of demanding industrial applications (such as: portable medical equipment, security systems and public transportation vehicles, etc.) and consumer design (including: wireless audio, home appliances, toys and novel products Capacitive key sensing, etc.) low-power recording and playback functions. The ISD9160 uses a Cortex-M0 microcontroller running at up to 50MHz, sophisticated power management functions, embedded flash memory and SRAM memory, real-time frequency (RTC) controller and general-purpose IO (GPIO), allowing designers to develop , Reliable and easy to develop audio recording and playback system and products. As the latest force of Nuvoton's well-known ChipCorder® product line, ISD9160 also simplifies the design time of the product and can reduce the cost of the bill of materials; and the highly integrated structure of the chip itself allows designers to avoid the need for many Peripheral chip. ISD9160 can also broadcast brand messages on a variety of consumer products, allowing manufacturers to allow their products to use chips that can play high-quality voice prompts and load corporate audio content, making their products different from other products on the market. ISD9160 integrates multiple voice interfaces such as microphone, Speaker driver and I 2S, as well as eight GPIOs that can perform capacitive sensing and provide analog functions; in addition, there are five power saving modes that allow the device to operate at different operating voltages , Making it suitable for portable / battery-powered products. Because the ISD9160 takes advantage of the Cortex-M0 processing engine, it can also add functions such as voice recognition, voice prompts, and long-term recording / playback that use a lot of CPU resources. The ARM Cortex-M0 core used by ISD9160 can provide 32-bit performance and low power consumption, but the price is only equivalent to the price of 8-bit microcontrollers. Designers can use their 32-bit architecture to develop complex algorithms such as speech recognition, text-to-speech (TTS), and wireless audio. These applications have used digital signal processors (DSPs) and / or other high-end ARMs in the past Device. Features of ISD9160: ARM Cortex-M0 core (up to 50MHz) Power management (five-level power control: <0.4 μA deep power-down mode (DPD); <2 μ A power-down mode (PD); <20 μA deep sleep mode (DSPD); and sleep mode (SPD) (Normal operating mode) On-chip memory (145KByte flash memory, 12KByte SRAM) Frequency control (48M / 32MHz built-in trimmed oscillator and ultra-low power 10KHz oscillator, 32 KHz RTC crystal oscillator interface) GPIO (Four IO modes, selectable input method, interchangeable pull-up IO) Analog / digital converter ADC (16-bit longitude, 90dB signal-to-noise ratio, adjustable gain and microphone amplifier, and programmable dual fourth-order filter) Class-D direct Loudspeaker driver, can provide 1 watt output power (5 volts, 8 Ω speakers) Automatic gain control ALC (programmable gain / amplification, up to 61dB, microphone and speaker can be shared to reduce BOM cost) Timers (two, using 8-bit front permutation calculator and 24-bit resolution) Watchdog timer (switches can be set, multiple frequency sources, eight time-out periods can be selected) RTC counter (prompt recorder, select 12 or 24 hour system, can automatically identify leap year) Hardware loop detection / correction check code (CRC-16) (detection and correction of errors in wireless audio transmission) Port (UART, SPI, I 2C, I 2S) Optional external memory interface (SPI flash memory, SD / SDHC card) Multiple applications (portable medical devices such as voice blood glucose machines, glass breakage sensors used in security systems, voice prompts for public transportation vehicles, wireless Microphones, and baby / senior / disability monitoring assistance systems; touch panels on home appliances, voice (Prompted capacitive buttons; voice recognition toys, recordable key rings, novel products of well-known brands) Farid Noory, senior product marketing manager of Nuvoton, said: "ChipCorder® ISD9160's ARM core and highly integrated analog functions make it perfect for recording and playback, capacitive button sensing, and other demanding audio applications. "And added:" The architecture ensures that manufacturers can design full-featured SoC, economical and powerful audio products, to enter other industrial and consumer market segments.
