ISD1600B SERIES
1. GENERAL DESCRIPTION
The Winbond® ISD1600B ChipCorder® Series is a high quality, fully integrated, single-chip single-message 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 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.

5. PIN DESCRIPTION
PIN NAME SOIC / PDIP PIN NO. VSSD 1 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. REC FUNCTIONS 2 Record: The device starts recording whenever RECtransits 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. PLAYE 3 PLAYL 4 VSSA 5 Analog Ground: VSSA is the ground for analog circuits. It is important to have a separate path for each ground back to the system ground terminal to minimize noise. MIC+ 6 Microphone Positive Input: The input transfers the signal to the preamplifier. The internal Automatic Gain Control (AGC) circuit controls the gain of the preamplifier. An external microphone should be AC coupled to this pin via a series capacitor. The capacitor value, together with an internal 10 KΩ resistance on this pin, determines the low-frequency cutoff for the ISD1600B passband. MIC- 7 Microphone Negative Input: This is the inverting input to the microphone preamplifier. It provides input noise-cancellation, or common-mode rejection, when the microphone is connected differentially to the device. SP- 8 Speaker Negative : The SP-, Class D PWM output, provides a differential output with SP+ pin to drive 8Ω speaker or buzzer. During power down or recording, this pin is tri-stated. VSSP 9 PWM Ground: VSSP is the ground for PWM speaker driver. It is important to have a separate path for each ground back to the system ground terminal to minimize noise. - 7 -

PIN NAME SOIC / PDIP PIN NO. VCCA 10 Analog power supply: It is important to have a separate path for each power back to the power terminal to minimize the noises. Decoupling capacitors to VSSA should be as close to the device as possible. VCCP 10 VCCP: Power supply for PWM speaker drivers. It is important to have a separate path for each power back to the power terminal to minimize noise. Decoupling capacitors to VSSP should be as close to the device as possible. SP+ 11 Speaker Positive : The SP+, Class D PWM output, provide a differential output with SP- pin to drive an 8Ω speaker or buzzer directly. During power down or recording, this pin is tri-stated. AGC 12 Automatic Gain Control: The AGC dynamically adjusts the gain of the preamplifier to compensate the wide range of microphone input levels. The AGC allows the full range of signal to be recorded with minimal distortion. Nominal values of 4.7 µF give satisfactory results in most cases. Connecting this pin to ground provides maximum gain to the preamplifier circuitry. Conversely, connecting this pin to power supply provides minimum gain to the preamplifier circuitry. AUD 13 AUD: The AUD provides a single-ended current output to drive an external amplifier. During standby or recording, this pin is tri-stated. ROSC 14 Oscillator Resistor: This enables the user to vary the record and/or playback duration of the device. A resistor connected between the ROSC pin and VSSA determines the sample frequency for the ISD1600B device. Please refer to the Duration Section in Section 6.1. VCCD 15 Digital power supply: It is important to have a separate path for each power back to the power terminal to minimize noise. Decoupling capacitors should be as close to the device as possible. 16 LED output: This pin is Low during a record cycle and LED blinks during playback cycle. It can be used to drive an LED to indicate either a record or playback cycle is in progress. Note: [1]FUNCTIONS 600kΩ (typical). - 8 -

6. FUNCTIONAL DESCRIPTION
6.1. DETAILED DESCRIPTION
6.1.1 Audio Quality
Winbond’s patented ChipCorder® MLS technology provides natural high quality record and playback solution on a single chip. The input audio signals are stored directly into the non-volatile memory and are reproduced in its natural form without any compression artifacts caused by the digital speech solutions. A complete sample is stored in a single cell, minimizing the memory needed to store a single message. 6.1.2 Duration
The ISD1600B series offer single-chip solution with record & playback duration from 6.6 seconds to 40 seconds. Sampling frequency and duration are determined by an external resistor connected to the Rosc pin.

20 secs 25 secs 30 secs 40 secs
6.1.3 Flash Storage
The ISD1600B product utilizes the on-chip Flash memory providing zero-power message
storage. The message is retained for up to 100 years without power. In addition, the device can be re-recorded typically over 100,000 times. 6.1.4 Basic Operation
The ISD1600B ChipCorder® device is controlled by either the REC, or one of the two playback modes, PLAYE and PLAYL. The ISD1600B parts are configured for simple design in single-message application. Detailed operations are explained in Section 6.2. 6.1.5 vAlert
With vAlert option, after Record, the LED blinks slowly to indicate a new message exists. Once playback is performed, the LED will not blink again and resume to normal operating conditions.
6.1.6 Automatic Power-Down Mode
At the end of a playback or record cycle, the ISD1600B device automatically enters into a low-power mode, consuming typically 1µA, provided that PLAYE, PLAYL and REC are High (see DC parameters Section). During a playback cycle, the device powers down automatically

ISD1600B SERIES
at the end of the message. During a record cycle, the device powers down immediately after REC is released to High.
6.2. FUNCTIONAL DESCRIPTION EXAMPLE
The following example operating sequences demonstrate the functionality of the ISD1600B series.
6.2.1. Record a Message
The device starts recording from the beginning of the memory when REC transits from High to Low and stays at Low. A record cycle is completed when REC is pulled to High or entire memory is filled up. Then an End-of-Message (EOM) marker is written at the end of message, enabling a subsequent playback cycle to terminate appropriately. Hence, the device automatically enters into standby mode.
Record takes precedence over playback operation. If REC is pulled Low during a playback cycle, the playback immediately halts and recording starts from the beginning of the memory. Holding REC Low after recording will increase standby current consumption. 6.2.2. Edge-trigger Playback
A playback operation starts from the beginning of the memory when PLAYE detects a low going signal exceeding the specified debounced time. Playback continues until an EOM marker is encountered. Upon completion of a playback cycle, the device automatically enters into standby mode.
During playback, a subsequent low going signal will terminate the current playback operation. Holding this pin Low after playback operation will increase standby current consumption. 6.2.3. Level- trigger Playback
When PLAYL switches from High to Low and stays at Low, a playback starts from the beginning of the memory until either an EOM marker is reached, then it automatically powers down.
If PLAYL is pulled High at any time during playback, the playback operation stops immediately and the device enters into the power-down mode. 6.2.4. LED Operation
The LED is Low during recording, which turns on an LED as a recording indicator. However, during playback, the LED blinks a few times per second to indicate a playback operation. It returns to a High when operation stops. 6.2.5. ROSC Operation
The duration can be varied by changing the value of ROSC. This means the designer has the flexibility to choose different sampling frequency, up to 12 KHz, depending upon the needs. This feature allows frequency shifting where a recorded audio can be played back faster or slower than normal for special sound effects.
Another feature is a “Pause” function that can be activated by taking the ROSC resistor to VCC to stop playback momentarily, and to resume when the resistor is switched back to ground.

Notes:
* These components may be needed in order to optimize for the best voice quality and system performance,
which is also dependent upon the layout of the PCB. Pending upon system requirement, Cx can be 10 μF,
4.7 μF or other values. For R7, 1kΩ gives satisfactory result fro most cases. ** For Sampling Freq at 8 kHz, R4 = 80 KΩ
*** It is important to have a separate path for each ground and power back to related terminal to minimize the
noise. Also, the power supplies should be decoupled as close to the device as possible.
Good Audio Design Practices
Winbond’s ChipCorder are very high-quality single-chip voice recording and playback devices. To ensure the highest quality voice reproduction, it is important that good audio design practices on layout and power supply decoupling are followed. See Application Information links below for details.
