ISD17120SY

The revision number of the ISD1700 Series Multi-Message Single-Chip Voice Record & Playback Devices is 1.3-S2.

The publication release date of the ISD1700 Series Multi-Message Single-Chip Voice Record & Playback Devices was January 23, 2007.

The ISD1700 devices include an on-chip oscillator, microphone preamplifier with Automatic Gain Control (AGC), an auxiliary analog input, anti-aliasing filter, Multi-Level Storage (MLS) array, smoothing filter, volume control, Pulse Width Modulation (PWM) Class D speaker driver, and current/voltage output. They also support an optional "vAlert" feature that can be used as a new message indicator. ISD1700 devices are optimized for a wide range of battery or line-powered applications and are designed for operation in either standalone or microcontroller (SPI) mode. The devices incorporate a proprietary message management system that allows the chip to self-manage address locations for multiple messages, providing sophisticated messaging flexibility in a simple push-button environment. The ISD1700 devices have integrated message management systems for single-chip, push-button applications, with features such as recording, playback, erasing, volume control, status indication, and automatic power-down after each operation cycle. They also offer selectable sampling frequency controlled by an external oscillator resistor and selectable message duration ranging from 20 seconds to 480 seconds depending on the sampling frequency chosen. In summary, the ISD1700 Series includes devices with various integrated features and capabilities suitable for a range of applications.
