6. PIN DESCRIPTION

PIN NAME PIN NO. FUNCTION

A0-A7 1-6, 9, 10 Address Inputs: The address inputs have two functions,

depending on the level of the two Most Significant Bits (MSB)

of the address (A6 and A7).

If either or both of the two MSBs are LOW, all inputs are

interpreted as address bits and are used as the start address

for the current record or playback cycle. The address pins are

inputs only and do not output internal address information as

the operation progresses. Address inputs are latched by the

falling edge of PLAYE , PLAYL , or REC .

If both A6 & A7 are HIGH, then the device is in a special

operational mode for looping. Please refer to looping

capability section for details.

A0, A1, A2, A3, A4 and A5 have internal pull-down resistors,

while A6 and A7 have internal pull-up resistors. They can be

floating if not used. Each of these internal pull-up or pull-down

devices have a value of 50 K Ω to 100 K Ω.

VSSA, VSSD 12, 13

Ground: Similar to VCCA and VCCD, separate analog and digital

ground rails provide independent analog and digital ground

buses internally to minimize noise. These pins should be tied

together as close as possible to the device.

SP+, SP- 14, 15 Speaker Outputs: The differential SP+ and SP- pins are

designed to drive a 16Ω speaker directly. Conversely, with

single-ended connection, a coupling capacitor is needed

between the SP pin and the speaker. Besides, the output

power is about a quarter of that from differential output. The

speaker outputs are in high-impedance state during recording

and at VSSA during power down.

VCCA, VCCD 16, 28

Supply Voltages: Separate analog and digital powers provide

power to internal analog and digital circuits respectively to

minimize internal noises. These power buses are brought out

to separate pads and should be tied together as close to the

supply source as possible. It is important that the power

supplies are decoupled as close to the device as possible.

MIC 17

Microphone: The microphone input transfers its signal to the

on-chip preamplifier. An on-chip Automatic Gain Control

(AGC) circuit controls the gain of this preamplifier from –15 to

24dB. An external microphone should be AC coupled to this

pin via a series capacitor. The capacitor value, together with

the internal 10 KΩ resistance on this pin, determines the low-

frequency cutoff for the device passband. See Winbond’s

Application Information for additional information on low-

frequency cutoff calculation.

ISD1100 SERIES

Publication Release Date: March 2004

- 7 - Revision 1.0

PIN NAME PIN NO. FUNCTION

MIC REF 18 Microphone Reference: The MIC REF input is the inverting

input to the microphone preamplifier. This provides a noise-

canceling or common-mode rejection input to the device when

connected to a differential microphone.

AGC 19

Automatic Gain Control (AGC): The AGC input dynamically

adjusts the gain of the preamplifier to compensate for the wide

range of microphone input levels. The AGC allows the full

range of sound, from whispers to loud sounds, to be recorded

with minimal distortion. The “attack” time is determined by the

time constant of a 5 KΩ internal resistance and an external

capacitor (C6 of Figure 5 in Section 11) connected from the

AGC pin to VSSA. The “release” time is determined by the time

constant of an external resistor (R5) and an external capacitor

(C6) connected in parallel between the AGC pin and VSSA pin.

Nominal values of 470 KΩ and 4.7 µF give satisfactory results

in most cases. Tying this to ground gives maximum gain,

while tying it to VCCA gives minimum gain for the AGC

amplifier.

ANA IN 20 Analog Input: The ANA IN transfers an input signal to the

chip for recording. For microphone usage, this ANA IN pin

should be connected via an external capacitor to the ANA

OUT pin. This capacitor value, together with the 3 KΩ input

impedance of ANA IN, is selected to give additional cutoff at

the low-frequency end of the voice passband. If the desired

input is derived from a source other than a microphone, the

signal can be capacitively coupled into the ANA IN pin directly.

ANA OUT 21 Analog Output: This pin provides the preamplifier output to

the user. The voltage gain of the preamplifier is determined by

the voltage level at the AGC pin.

PLAYL [2][3] 23 Playback, Level-Activated: When this input signal is held

LOW, a playback cycle is initiated, and playback continues

until PLAYL is pulled HIGH, or an EOM marker is detected.

The device automatically powers down and enters into

standby mode upon completion of a playback cycle. This pin

has an internal pull-up resistor.

PLAYE [2][3] 24 Playback, Edge-Activated: When a LOW-going transition is

detected on this pin, a playback cycle begins. Taking PLAYE

HIGH during a playback cycle will not terminate the current

cycle. Playback continues until an EOM is encountered. Upon

completion of a playback cycle, the device automatically

powers down and enters into standby mode. This pin has an

internal pull-up device.

ISD1100 SERIES

PIN NAME PIN NO. FUNCTION

RECLED 25 Record LED: The RECLED output is LOW during a record

cycle. It can be used to drive an LED to indicate a record cycle

is in progress. In addition, RECLED pulses LOW

momentarily when an end-of-message is encountered in a

playback operation.

XCLK 26

External Clock: The external clock input has an internal pull-

down resistor. The ISD1100 is configured at the factory with

an internal sampling clock frequency that guarantees its

minimum nominal record/playback time. For instance, an

ISD1110 operating within specification will be observed to

always have a minimum of 10 seconds of recording time. The

sampling frequency is then maintained to a variation of ±2.25

percent over the commercial temperature and operating

voltage ranges while still maintaining the minimum duration

specified. As a result some devices will have a few percent

more than nominal recording time. If greater precision is

required, the device can be clocked through the XCLK pin as

follows:

EXTERNAL CLOCK SAMPLE RATES

Part Number Sample Rate Required Clock

ISD1110 6.4 kHz 819.2 kHz

ISD1112 5.3 kHz 682.7 kHz

These recommended clock rates should not be varied

because the anti-aliasing and smoothing filters are fixed, and

aliasing problems can occur if the sample rate differs from the

one recommended. The duty cycle on the input clock is not

critical, as the clock is immediately divided by two. If the

XCLK is not used, this pin must be grounded. Please see

Application Information for the ISD1100 series for more details

on external clocking.

ISD1100 SERIES

Publication Release Date: March 2004

- 9 - Revision 1.0

PIN NAME PIN NO. FUNCTION

REC [1][3] 27 Record: The REC input is an active-LOW signal. The device

records whenever REC is LOW. This signal must remain

LOW for the duration of the recording. A record cycle is

completed when REC is pulled HIGH or the memory space

is filled up.

REC takes precedence over either playback ( PLAYE or

PLAYL ) signal. If REC is pulled LOW during a playback

cycle, the playback immediately ceases and recording begins.

An end-of-message (EOM) marker is internally recorded,

enabling a subsequent playback cycle to terminate

appropriately. The device automatically powers down into

standby mode when REC goes HIGH. This pin has an

internal pull-up resistor.

NC 11

NC: No connect

Notes:

[1] The REC signal is debounced for 50 ms on the rising edge to prevent a false retriggering from a push-

button switch.

[2] During playback, if either PLAYE or PLAYL is held LOW during EOM or OVF, the device will still

enter into standby mode and the internal oscillator and timing generator will stop. However, the rising

edge of PLAYE and PLAYL are not debounced and any subsequent falling edge (particularly switch

bounce) present on the input pins will initiate another playback.

[3] REC , PLAYL and PLAYE have internal pull-ups to VCC. Holding on these pins LOW wil increase

standby current consumption.

7. FUNCTIONAL DESCRIPTION

7.1. DETAILED DESCRIPTION

Speech/Sound Quality

Winbond’s patented ChipCorder® technology provides natural audio record and playback. The

ISD1100 series include devices of 5.3 kHz and 6.4 kHz sampling frequencies, allowing the user a

choice of speech quality options. The input voice signals are stored directly into non-volatile EEPROM

cells and are reproduced without the synthetic effect often heard with digital solid-state speech

solutions. A complete sample is stored in a single cell, minimizing the memory necessary to store a

recording of a given duration.

Duration

The ISD1100 series offer single-chip solutions of 10 and 12 seconds duration.

ISD1112 12 5.3 2.2

* 3dB roll-off-point….

EEPROM Storage

One of the benefits of Winbond’s ChipCorder® technology is the use of on-chip non-volatile memory,

providing zero-power message storage. The message is retained for up to 100 years typically without

power. In addition, the device can be re-recorded typically over 100,000 times.

Basic Operation

The ISD1100 ChipCorder® series are controlled by a single signal, REC , or one of two playback

control signals, PLAYE (edge-activated playback), and PLAYL (level-activated playback). The

ISD1100 series parts are configured for simplicity of design in a single/multiple-message application.

Using the address lines will allow multiple message applications.

Automatic Power-Down Mode

At the end of a playback or record operation, the ISD1100 series automatically enters into a standby

mode, with typically 0.5 µA current. During a playback cycle, the device powers down automatically at

the end of the message. During a record cycle, the device powers down immediately after REC is

released HIGH.

Addressing

In addition to single-message application, the ISD1100 series provides a full addressing capability for

multiple message application.

The memory array of ISD1100 series has 80 distinct addressable rows, providing the below

resolutions per row. See Application Information for address tables of ISD1100 series.

TABLE 2: DEVICE PLAYBACK/RECORD DURATIONS

Part Number Minimum Duration (per ROW)

ISD1110 125 msec

ISD1112 150 msec

Looping Capability

The ISD1100 series device has a built-in looping function enabling it to continuously repeat a single

message. This mode is accomplished by taking A3, A6 and A7 pins HIGH simultaneously to

continuously loop from the end of the message to the beginning of the message. Looping is initiated

by a negative transition on PLAYE pin with A3, A6 and A7 held HIGH, then PLAYE is brought back

to HIGH. Looping will continue indefinitely with all three control pins ( PLAYE ,PLAYL ,REC )

remaining HIGH, until PLAYL is pulsed to LOW, which ends the looping.

Functional Description Example

The following operating sequence example demonstrates the functionality of the ISD1100 series.

1. Record a message:

Pulling the REC signal LOW initiates a record cycle from current location. When REC is

held LOW, the recording continues. Until the memory array is filled up or when REC is

pulled HIGH, recording ceases. An EOM marker is written at the end of message. Then the

device will automatically power down.

2. Edge-activated playback:

Pulling the PLAYE signal LOW initiates a playback cycle from the beginning of the message

until the entire message is played. The rising edge of PLAYE has no effect on operation.

When the EOM marker is encountered, the device automatically powers down. A subsequent

falling edge on PLAYE initiates a new playback operation from the beginning of the

message.

3. Level-activated playback:

Holding the PLAYL signal LOW initiates a playback cycle from the beginning of the

message, until PLAYL is pulled HIGH or when the EOM marker is encountered, playback

operation stops and the device automatically powers down.

4. Record (interrupting playback).

The REC signal takes precedence over playback operation. Holding REC LOW initiates a

new record operation from current location, regardless of any current operation in progress.

5. RECLED operation.

During record, the RECLED output pin provides an active-LOW signal, which can be used to

drive an LED as a “record-in-progress” indicator. It returns to a HIGH state when the REC

pin is pulled HIGH or when the recording is completed due to the memory being filled.

However, during playback, this pin also pulses LOW to indicate an EOM at the end of a

message.

Applications Note

Some users may experience an unexpected recording taking place when their circuit is powered up,

or the batteries are changed, and VCC rises faster than REC . This undesired recording prevents

playback of the previously recorded message. A spurious EOM marker appears at the very beginning

of the memory, preventing access to the original message, and nothing is played.

To prevent this occurrence, install a capacitor (approx. 0.001 µF) between the REC and VCC pins.

This pulls the control pin voltage up with VCC as it rises. Once the voltage is HIGH, the pull-up device

will keep the pin HIGH until intentionally pulled LOW, preventing the false EOM marker.

Since this condition is dependent upon factors such as the capacitance of the user’s printed circuit

board, not all circuit designs will exhibit the spurious marker. It is recommended, however, that the

capacitor is included for design reliability. A more detailed explanation and resolution of this

occurrence is described in Application Information.
