NUVOTON'S ChipCorder® is a complete, single chip solution for voice and audio recording and playback applications

Applications

  • Vending Machines
  • Warning signals
  • Door chimes
  • Security
  • Answering machines

The Nuvoton ISD1700 ChipCorder® Series is a high quality, fully integrated, single-chip multi-message voice record and playback device ideally suited to a variety of electronic systems. The message duration is user selectable in ranges from 26 to 120 seconds, depending on the specific device. The sampling frequency of each device can also be adjusted from 4 kHz to 12 kHz with an external resistor, giving the user greater flexibility in duration versus recording quality for each application. Operating voltage spans a range from 2.4 V to 5.5 V to ensure that the ISD1700 devices are optimized for a wide range of battery or line-powered applications.

The ISD1700 is designed for operation in either stand-alone or microcontroller (SPI) mode. The device incorporates a proprietary message management system that allows the chip to self-manage address locations for multiple messages. This unique feature provides sophisticated messaging flexibility in a simple, push-button environment. The devices include an on-chip oscillator (with external resistor control), microphone preamplifier with Automatic Gain Control (AGC), an auxiliary analogue input, anti-aliasing filter, Multi-Level Storage (MLS) array, smoothing filter, volume control, Pulse Width Modulation (PWM) Class D speaker driver, and current output.

The ISD1700 devices also support an optional 'vAlert' (voiceAlert) feature that can be used as a new message indicator. With vAlert, the IC strobes an external LED to indicate that a new message is present. Four special sound effect locations are reserved for audio confirmation of commands, such as 'Start Record', 'Stop Record' , and 'Erase'.

Recordings are stored in on-chip Flash memory cells, providing zero-power message storage. This unique single-chip solution is made possible through Nuvotons's patented Multi-Level Storage (MLS) technology. Audio data is stored directly in solid-state memory without digital compression, providing superior quality voice and music reproduction.

Voice signals can be fed into the chip through two independent paths: a differential microphone input and a single-ended analogue input. For outputs, the ISD1700 provides a Pulse Width Modulation (PWM) Class D speaker driver and a separate analogue output simultaneously. The PWM can directly drive a standard 8? speaker or typical buzzer, while the separate analogue output can be configured as a single-ended current or voltage output to drive an external amplifier.

The ISD1700 devices automatically enter into power down mode for power conservation when an operation is completed. In the SPI mode, the user has full control via the serial interface in operating the device. This includes random access to any location inside the memory array by specifying the start address and end address of operations. SPI mode also allows access to the Analogue Path Configuration (APC) register. This register allows flexible configuration of audio paths, inputs, outputs and mixing. The APC default configuration for stand-alone mode can also be modified by storing the APC to a non-volatile register (NVCFG) that is loaded at initialization. Utilizing the capabilities of the ISD1700 Series, designers have the control and flexibility to implement high-end products.
