GENERAL DESCRIPTION The Winbond® ISD1600B ChipCorder® Series is a high quality, fully integrated, single-chip singlemessage voice record and playback device ideally suited to a variety of electronic systems. The message duration is user selectable in ranges from 6.6 seconds to 40 seconds, depending on the www.DataSheet4U.com 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 ISD1600B devices are optimized for a wide range of battery or line-powered applications. The devices include an on-chip oscillator (with external resistor control), microphone preamplifier with Automatic Gain Control (AGC), anti-aliasing filter, Multi-Level Storage (MLS) array, smoothing filter, Pulse Width Modulation (PWM) Class D speaker driver, and current output. Voice signals can be fed into the chip through a differential microphone input for recording. The PWM output can directly drive a standard 8 Ω speaker or a typical buzzer, while the separate single-ended current output can drive an external amplifier. Recordings are stored into the on-chip Flash memory cells, providing zero-power message storage. This unique single-chip solution is made possible through Winbond’s patented Multi-Level Storage (MLS) technology. Audio data are stored directly in solid-state memory without digital compression, providing superior quality voice and music reproduction. The ISD1600B Series also supports 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. -3- Publication Release Date: Jan. 23, 2007 Revision 1.2 ISD1600B SERIES 2.

PIN DESCRIPTION PIN NAME VSSD www.DataSheet4U.com SOIC / PDIP PIN NO. 1 FUNCTIONS Digital Ground: VSSD is the ground for digital circuits. It is important to have a separate path for each ground back to the system ground terminal to minimize noise. Record: The device starts recording whenever REC transits from High to Low and stays at Low. Recording stops when the signal returns to High. This pin has an internal pull-up resistor [1] and an internal debounce on falling edge. Edge-trigger Playback: A playback operation starts when this input detects a low going signal exceeding the specified debounced time. This pin has an internal pull-up resistor [1] and an internal debounce on both falling & rising edge. Level-trigger Playback: A playback operation begins when this input detects a low going signal and remains at Low. Playback stops when the signal returns to High. This pin has an internal pull-up resistor [1] and an internal debounce on falling edge. Analog Ground: VSSA is the ground for analog circuits. It
