pdf (464k) technical documentation

Nuvoton Technology Corp. has developed the new ChipCorder® ISD9160 device which is the first ChipCorder solution based on the 32-bit ARM® Cortex™-M0 microcontroller core. It is designed to low-power audio recording and playback in a wide range of industrial applications, such as portable medical devices, security systems and public transit vehicles as well as in consumer designs, such as wireless audio, touch panels, home appliances, toys etc. Its highly integrated architecture eliminates the need for various peripheral chips and thus simplifies products' design time and reduces materials costs.


Basic parameters:
  • ARM® Cortex™-M0 core (operating frequency up to 50MHz)
  • comprehensive power management (wide voltage range, four levels of power control)
  • Deep Power Down mode
  • internal or external memory storage
  • internal memory: 145 KB ISP Flash memory (APROM) for program code and data storage, 4 KB Flash (shared with APROM) for ISP loader, 12 KB SRAM
  • optional external memory interfaces (SPI Flash, SD card)
  • internal trimmable oscillator with the range of 16...50 MHz and external 32 kHz RTC crystal
  • digital compression in the range of 4...16 kbps (2/3/4/5-bit ADPCM up to 32 kHz, 8/16-bit PCM)
  • record time up to 60 seconds (based on 16 kbps compression)
  • 24 GPIOs
  • two 24-bit timers
  • Watchdog timer
  • RTC counter
  • 32 interrupts
  • interfaces: UART, 2xSPI, I2C, I2S with external audio CODEC
  • two 16-bit PWM generators
  • microphone input
  • 16-bit Analog-to-digital converter (ADC) with SNR of 80 dB
  • Programmable Gain Amplifier
  • differential Class-D speaker driver delivering 1W output power at 8 ? speaker
  • wide operating voltage: 2.5 to 5.5 V
  • industrial operating temperature: -40 to +85 °C
  • package: LQFP-48, RoHS
  • development tools: ISD9160_EVK and ISD9160_DMK
