1. GENERAL DESCRIPTION
The ISD5100 ChipCorder Series provide high quality, fully integrated, single-chip Record/Playback
solutions for 1- to 16-minute messaging applications that are ideal for use in cellular phones,
automotive communications, GPS/navigation systems and other portable products. The ISD5100
Series products are an enhancement of the ISD5000 architecture, providing: 1) the I2C serial port address, control and duration selection are accomplished through an I2C interface to minimize pin
count (ONLY two control lines required); 2) the capability of storing digital data, in addition to analog
data. This feature allows customers to store phone numbers, system configuration parameters and
message address locations for message management capability; 3) Various internal circuit blocks can
be individually powered-up or -down for power saving.
The ISD5100 Series include:
•
ISD5116 from 8 to 16 minutes
•
ISD5108 from 4 to 8 minutes
•
ISD5104 from 2 to 4 minutes
•
ISD5102 from 1 to 2 minutes
Analog functions and audio gating have also been integrated into the ISD5100 Series products to
allow easy interface with integrated digital cellular chip sets on the market. Audio paths have been
designed to enable full duplex conversation record, voice memo, answering machine (including
outgoing message playback) and call screening features. This product enables playback of messages
while the phone is in standby, AND both simplex and duplex playback of messages while on a phone
call.
Additional voice storage features for digital cellular phones include: 1) a personalized outgoing
message can be sent to the person by getting caller-ID information from the host chipset, 2) a private
call announce while on call can be heard from the host by giving caller-ID on call waiting information
from the host chipset.
Logic Interface Options of 2.0V and 3.0V are supported by the ISD5100 Series to accommodate
portable communication products (2.0- and 3.0-volt required).
Like other ChipCorder® products, the ISD5100 Series integrate the sampling clock, anti-aliasing and
smoothing filters, and the multi-level storage array on a single-chip. For enhanced voice features, the
ISD5100 Series eliminate external circuitry by integrating automatic gain control (AGC), a power
amplifier/speaker driver, volume control, summing amplifiers, analog switches, and a car kit interface.
Input level adjustable amplifiers are also included, providing a flexible interface for multiple
applications.
Recordings are stored into on-chip nonvolatile memory cells, providing zero-power message storage.
This unique, single-chip solution is made possible through Winbond’s patented multilevel storage
technology. Voice and audio signals are stored directly into solid-state memory in their natural,
uncompressed form, providing superior quality on voice and music reproduction.

7. FUNCTIONAL DESCRIPTION
7.1. OVERVIEW
7.1.1 Speech/Voice Quality
The ISD5100 ChipCorder Series can be configured via software to operate at 4.0, 5.3, 6.4 or 8.0 kHz
sampling frequency to select appropriate voice quality. Increasing the duration decreases the
sampling frequency and bandwidth, which affects audio quality. The table in the following section
shows the relationship between sampling frequency, duration and filter pass band.
7.1.2. Duration
To meet system requirements, the ISD5100 Series are single-chip solution, which provide 1 to 16
minutes of voice record and playback, depending upon the sample rates chosen.

7.1.3. Flash Technology
One of the benefits of Winbond’s ChipCorder technology is the use of on-chip Flash memory, which
provides zero-power message storage. The message is retained for up to 100 years (typically) without
power. In addition, the device can be re-recorded over 10,000 times (typically) for the digital data and
over 100,000 times (typically) for the analog messages.
A new feature has been added that allows memory space in the ISD5100 Series to be allocated to
either digital or analog storage when recorded. The fact that a section has been assigned digital or
analog data is stored in the Message Address Table by the system microcontroller when the recording
is made.
7.1.4. Microcontroller Interface
The ISD5100 Series are controlled through an I2C 2-wire interface. This synchronous serial port
allows commands, configurations, address data, and digital data to be loaded into the device, while
allowing status, digital data and current address information to be read back from the device. In
addition to the serial interface, two other status pins can feedback to the microcontroller for enhanced
-9-
Publication Release Date: October, 2003
Revision 0.2
ISD5100 – SERIES
interface. These are the RAC timing pin and the INT pin for interrupts to the controller.
Communications with all the internal registers of any operations are through the serial bus, as well as
digital memory Read and Write operations.
7.1.5. Programming
The ISD5100 Series are also ideal for playback-only applications, where single or multiple messages
may be played back when desired. Playback is controlled through the I2C interface. Once the desired
message configuration is created, duplicates can easily be generated via a third-party programmer.
For more information on available application tools and programmers, please see the Winbond web
site at www.winbond-usa.com
7.2. FUNCTIONAL DETAILS
The ISD5100 Series are single chip solutions for analog and digital data storage. The array can be
divided between analog and digital storage according to user’s choice, when the device is configured.
The below block diagram shows that the ISD5116 device can be easily designed into a telephone
answering machine (TAD). Both Mic inputs transmit the voice input signal from the microphone to
perform OGM recording, as well as to record the speech during phone conversation (simplex).
When the TAD is activated, the voice of the other party from the phone line feeds into the AUX IN, and
is recorded into the ISD5116 device. Then the new messge is usually indicated with blinking new
message LED. Hence, during playback, the recorded message is sent out to speaker with volume
control.
Two I2C pins are used for all communications between the ChipCorder and the
microcontroller for analog and/or digital storage, and the two outputs, INT and RAC are feedback to
microcontroller for message management.

For duplex recording, speech from Mic inputs and message from received path can be directly

operation, voice from Mic inputs are fed to AUX OUT and transmitted to the phone line, while
message from other party is input from the AUX IN, then fed through to the speaker for listening.
The ISD5100 device has the flexibility for other applications, because the audio paths can be
configured differently, with each circuit block being powered-up or –down individually, according to the
applications requirement.
7.2.1. Internal Registers
The ISD5100 Series have multiple internal registers that are used to store the address information and
the configuration or set-up of the device. The two 16-bit configuration registers control the audio paths
through the device, the sample frequency, the various gains and attenuations, power up and down of
different sections, and the volume settings. These registers are discussed in detail in section 7.3.5.
7.2.2. Memory Architecture
The ISD5100 Series memory array are arranged in various pages (or rows) of each 2048 bits as
follows. The primary addressing for the pages are handled by 11 bits of address input in the analog
mode.
A memory page is 2048 bits organized as thirty-two 64-bit "blocks" when used for digital storage. The
contents of a page are either analog or digital. This is determined by instruction (opcode) at the time
the data is written. A record of where is analog and where is digital, is stored in a message address
table (MAT) by the system microcontroller. The MAT is a table kept in the microcontroller memory that
defines the status of each message “page”. It can be stored back into the ISD5100 Series if the power
fails or the system is turned off. Using this table allows efficient message management. Segments of
messages can be stored wherever there is available space in the memory array. [This is explained in
detail for the ISD5008 in Applications Note #9 and will be similarly described in a later Note for the
ISD5100-Series.]

When a page is used for analog storage, the same 32 blocks are present but there are 8 EOM (Endof-Message) markers. This means that for each 4 blocks there is an EOM marker at the end. Thus,
when recording, the analog recording will stop at any one of eight positions. At 8 kHz sampling
frequency, this results in a resolution of 32 msec when ENDING an analog recording. Beginning an
analog recording is limited to the 256 msec resolution provided by the 11-bit address. A recording
does not immediately stop when the Stop command is given, but continues until the 32 millisecond
block is filled. Then a bit is placed in the EOM memory to develop the interrupt that signals a
message is finished playing in the Playback mode.

Revision 0.2
ISD5100 – SERIES
Digital data is sent and received serially over the I2C interface. The data is serial-to-parallel converted
and stored in one of two alternating (commutating) 64-bit shift registers. When an input register is full,
it becomes the register that is parallel written into the array. The prior write register becomes the new
serial input register. A mechanism is built-in to ensure there is always a register available for storing
new data.
Storing data in the memory is accomplished by accepting data one byte at a time and issuing an
acknowledge. If data is coming in faster than it can be written, the chip issues an acknowledge to the
host microcontroller, but holds SCL LOW until it is ready to accept more data. (See section 7.5.2 for
details).
The read mode is the opposite of the write mode. Data is read into one of two 64-bit registers from the
array and serially sent to the I2C interface. (See section 7.5.3 for details).
7.3. OPERATIONAL MODES DESCRIPTION
7.3.1. I2C Interface
To use more than four ISD5100 Series devices in an application requires some external switching of
the I2C interface.
I2C interface
Important note: The rest of this data sheet will assume that the reader is familiar with the
I2C serial interface. Additional information on I2C may be found in section 10 on page 72 of
this document. If you are not familiar with this serial protocol, please read this section to
familiarize yourself with it. A large amount of additional information on I2C can also be
found on the Philips web page at http://www.philips.com/.
I2C Slave Address
The ISD5100 Series have 7-bit slave address of <100 00xy> where x and y are equal to the state,
respectively, of the external address pins A1 and A0. Because all data bytes are required to be 8
bits, the LSB of the address byte is the Read/Write selection bit that tells the slave whether to transmit
or receive data. Therefore, there are 8 possible slave addresses for the ISD5100-Series. These
are:

ISD5100 Series I2C Operation Definitions
There are many control functions used to operate the ISD5100-Series. Among them are:
7.3.1.1. Read Status Command:
The Read Status command is a read request from the Host processor to the ISD5100 Series
without delivering a Command Byte. The Host supplies all the clocks (SCL). In each case, the
entity sending the data drives the data line (SDA). The Read Status Command is executed by the
following I2C sequence.
1. Host executes I2C START
2. Send Slave Address with R/W bit = “1” (Read) 81h
3. Slave (ISD5100-Series) responds back to Host an Acknowledge (ACK) followed by 8-bit
Status word
4. Host sends an Acknowledge (ACK) to Slave
5. Wait for SCL to go HIGH
6. Slave responds with Upper Address byte of internal address register
7. Host sends an ACK to Slave
8. Wait for SCL to go HIGH
9. Slave responds with Lower Address byte of internal address register (A[4:0] will always return
set to 0.)
10. Host sends a NO ACK to Slave, then executes I2C STOP

Note that the processor could have sent an I2C STOP
after the Status Word data transfer and aborted the
transfer of the Address bytes.

7.3.2. I2C Control Registers
The ISD5100 Series are controlled by loading commands to, or, reading from, the internal command,
configuration and address registers. The Command byte sent is used to start and stop recording, write
or read digital data and perform other functions necessary for the operation of the device.
Command Byte
Control of the ISD5100 Series are implemented through an 8-bit command byte, sent after the 7-bit
device address and the 1-bit Read/Write selection bit. The 8 bits are:
Global power up bit
DAB bit: determines whether device is performing an analog or digital function
3 function bits: these determine which function the device is to perform in conjunction
with the DAB bit.
3 register address bits: these determine if and when data is to be loaded to a register

7.3.4. Data Bytes
2
In the I C write mode, the device can accept data sent after the command byte. If a register load
option is selected, the next two bytes are loaded into the selected register. The format of the data is
MSB first, the I2C standard. Thus to load DATA<15:0> into the device, DATA<15:8> is sent first, the
byte is acknowledged, and DATA<7:0> is sent next. The address register consists of two bytes. The
format of the address is as follows:
ADDRESS<15:0>
= PAGE_ADDRESS<10:0>, BLOCK_ADDRESS<4:0>
Note: if an analog function is selected, the block address bits must be set to 00000. Digital
Read and Write are block addressable.
When the device is polled with the Read Status command, it will return three bytes of data. The first
byte is the status byte, the next the upper address byte and the last the lower address byte. The status
register is one byte long and its bit function is:
STATUS<7:0> = EOM, OVF, READY, PD, PRB, DEVICE_ID<2:0>
Lower address byte will always return the block address bits as zero, either in digital or analog mode.
The functions of the bits are:
EOM
BIT 7
Indicates whether an EOM interrupt has occurred.
OVF
BIT 6
Indicates whether an overflow interrupt has occurred.
READY
BIT 5
Indicates the internal status of the device – if READY is LOW
no new commands should be sent to device, i.e. Not Ready.
PD
BIT 4
Device is powered down if PD is HIGH.
PRB
BIT 3
Play/Record mode indicator. HIGH=Play/LOW=Record.
DEVICE_ID
BIT 0, 1, 2
An internal device ID. ISD5116 = 001;
ISD5104 = 100 and ISD5102 = 101.
ISD5108 = 010;
It is recommended that you read the status register after a Write or Record operation to ensure that
the device is ready to accept new commands. Depending upon the design and the number of pins
available on the controller, the polling overhead can be reduced. If INT and RAC are tied to the
microcontroller, it does not have to poll as frequently to determine the status of the ISD5100-SERIES.

7.3.5. Configuration Resiter Bytes
The configuration register bytes are defined, in detail, in the drawings of section 7.4 on page 29. The
drawings display how each bit enables or disables a function of the audio paths in the ISD5100Series. The tables below give a general illustration of the bits. There are two configuration registers,
CFG0 and CFG1, so there are four 8-bit bytes to be loaded during the set-up of the device.

7.3.6. Power-up Sequence
This sequence prepares the ISD5100 Series for an operation to follow, waiting the Tpud time before
sending the next command sequence.
1.
Send I2C POWER UP
2.
Send one byte 10000000 {Slave Address, R/W = 0} 80h
3.
Slave ACK
4.
Wait for SCL High
5.
Send one byte 10000000 {Command Byte = Power Up} 80h
6.
Slave ACK
7.
Wait for SCL High
8.
Send I2C STOP
Playback Mode
The command sequence for an analog Playback operation can be handled several ways. The most
straightforward approach would be to incorporate a single four byte exchange, which consists of the
Slave Address (80h), the Command Byte (A9h) for Play Analog @ Address, and the two address
bytes.

ISD5100 – SERIES
Record Mode
The command sequence for an Analog Record would be a four byte sequence consisting of the Slave
Address (80h), the Command Byte (91h) for Record Analog @ Address, and the two address bytes.
See “Load Command Byte Register (Address Load)” in section 7.3.2 on page 17.
7.3.7. Feed Through Mode
The previous examples were dependent upon the device already being powered up and the various
paths being set through the device for the desired operation. To set up the device for the various
paths requires loading the two 16-bit Configuration Registers with the correct data. For example, in
the Feed Through Mode the device only needs to be powered up and a few paths selected.
This mode enables the ISD5100 Series to connect to a cellular or cordless base band phone chip set
without affecting the audio source or destination. There are two paths involved, the transmit path and
the receive path. The transmit path connects the Winbond chip’s microphone source through to the
microphone input on the base band chip set. The receive path connects the base band chip set’s
speaker output through to the speaker driver on the Winbond chip. This allows the Winbond chip to
substitute for those functions and incidentally gain access to the audio to and from the base band chip
set.
To set up the environment described above, a series of commands need to be sent to the ISD5100Series. First, the chip needs to be powered up as described in this section. Then the Configuration
Registers must be filled with the specific data to connect the paths desired. In the case of the Feed
Through Mode, most of the chip can remain powered down. The following figure illustrates the
affected paths.

Mode. The rest of the chip will be powered down to conserve power. The bold lines highlight the audio
paths. Note that the Microphone to ANA OUT +/– path is differential.
- 22 -
ISD5100 – SERIES
To select this mode, the following control bits must be configured in the ISD5100 Series configuration
registers. To set up the transmit path:
1. Select the FTHRU path through the ANA OUT MUX—Bits AOS0, AOS1 and AOS2 control the
state of the ANA OUT MUX. These are the D6, D7 and D8 bits respectively of Configuration
Register 0 (CFG0) and they should all be ZERO to select the FTHRU path.
2. Power up the ANA OUT amplifier—Bit AOPD controls the power up state of ANA OUT. This is
bit D5 of CFG0 and it should be a ZERO to power up the amplifier.
To set up the receive path:
1. Set up the ANA IN amplifier for the correct gain—Bits AIG0 and AIG1 control the gain settings
of this amplifier. These are bits D14 and D15 respectively of CFG0. The input level at this pin
determines the setting of this gain stage. The ANA IN Amplifier Gain Settings table on page
36 will help determine this setting. In this example, we will assume that the peak signal never
goes above 1 volt p-p single ended. That would enable us to use the 9 dB attenuation setting,
or where D14 is ONE and D15 is ZERO.
2. Power up the ANA IN amplifier—Bit AIPD controls the power up state of ANA IN. This is bit
D13 of CFG0 and should be a ZERO to power up the amplifier.
3. Select the ANA IN path through the OUTPUT MUX—Bits OPS0 and OPS1 control the state of
the OUTPUT MUX. These are bits D3 and D4 respectively of CFG0 and they should be set to
the state where D3 is ONE and D4 is ZERO to select the ANA IN path.
4. Power up the Speaker Amplifier—Bits OPA0 and OPA1 control the state of the Speaker and
AUX amplifiers. These are bits D1 and D2 respectively of CFG0. They should be set to the
state where D1 is ONE and D2 is ZERO. This powers up the Speaker Amplifier and
configures it for its higher gain setting for use with a piezo speaker element and also powers
down the AUX output stage.
The status of the rest of the functions in the ISD5100 Series chip must be defined before the configuration registers settings are updated:
1. Power down the Volume Control Element—Bit VLPD controls the power up state of the
Volume Control. This is bit D0 of CFG0 and it should be set to a ONE to power down this
stage.
2. Power down the AUX IN amplifier—Bit AXPD controls the power up state of the AUX IN input
amplifier. This is bit D10 of CFG0 and it should be set to a ONE to power down this stage.
3. Power down the SUM1 and SUM2 Mixer amplifiers—Bits S1M0 and S1M1 control the SUM1
mixer and bits S2M0 and S2M1 control the SUM2 mixer. These are bits D7 and D8 in CFG1
and bits D5 and D6 in CFG1 respectively. All 4 bits should be set to a ONE to power down
these two amplifiers.
4. Power down the FILTER stage—Bit FLPD controls the power up state of the FILTER stage in
the device. This is bit D1 in CFG1 and should be set to a ONE to power down the stage.
5. Power down the AGC amplifier—Bit AGPD controls the power up state of the AGC amplifier.
This is bit D0 in CFG1 and should be set to a ONE to power down this stage.
- 23 -
Publication Release Date: October, 2003
Revision 0.2
ISD5100 – SERIES
6. Don’t Care bits—The following stages are not used in Feed Through Mode. Their bits may be
set to either level. In this example, we will set all the following bits to a ZERO. (a). Bit INS0, bit
D9 of CFG0 controls the Input Source Mux. (b). Bits AXG0 and AXG1 are bits D11 and D12
respectively in CFG0. They control the AUX IN amplifier gain setting. (c). Bits FLD0 and FLD1
are bits D2 and D3 respectively in CFG1. They control the sample rate and filter band pass
setting. (d). Bit FLS0 is bit D4 in CFG1. It controls the FILTER MUX. (e). Bits S1S0 and S1S1
are bits D9 and D10 of CFG1. They control the SUM1 MUX. (f). Bits VOL0, VOL1 and VOL2
are bits D11, D12 and D13 of CFG1. They control the setting of the Volume Control. (g). Bits
VLS0 and VLS1 are bits D14 and D15 of CFG1. They control the Volume Control MUX.
The end result of the above set up is
CFG0=0100 0100 0000 1011 (hex 440B)
and
CFG1=0000 0001 1110 0011 (hex 01E3).
Since both registers are being loaded, CFG0 is loaded, followed by the loading of CFG1. These two
registers must be loaded in this order. The internal set up for both registers will take effect synchronously with the rising edge of SCL.
7.3.8. Call Record
The call record mode adds the ability to record an incoming phone call. In most applications, the
ISD5100 Series would first be set up for Feed Through Mode as described above. When the user
wishes to record the incoming call, the setup of the chip is modified to add that ability. For the purpose
of this explanation, we will use the 6.4 kHz sample rate during recording.
The block diagram of the ISD5100 Series shows that the Multilevel Storage array is always driven
from the SUM2 SUMMING amplifier. The path traces back from there through the LOW PASS Filter,
THE FILTER MUX, THE SUM1 SUMMING amplifier, the SUM1 MUX, then from the ANA in amplifier.
Feed Through Mode has already powered up the ANA IN amp so we only need to power up and
enable the path to the Multilevel Storage array from that point:
1. Select the ANA IN path through the SUM1 MUX—Bits S1S0 and S1S1 control the state of the
SUM1 MUX. These are bits D9 and D10 respectively of CFG1 and they should be set to the
state where both D9 and D10 are ZERO to select the ANA IN path.
2. Select the SUM1 MUX input (only) to the S1 SUMMING amplifier—Bits S1M0 and S1M1
control the state of the SUM1 SUMMING amplifier. These are bits D7 and D8 respectively of
CFG1 and they should be set to the state where D7 is ONE and D8 is ZERO to select the
SUM1 MUX (only) path.
3. Select the SUM1 SUMMING amplifier path through the FILTER MUX—Bit FLS0 controls the
state of the FILTER MUX. This is bit D4 of CFG1 and it must be set to ZERO to select the
SUM1 SUMMING amplifier path.
- 24 -
ISD5100 – SERIES
4. Power up the LOW PASS FILTER—Bit FLPD controls the power up state of the LOW PASS
FILTER stage. This is bit D1 of CFG1 and it must be set to ZERO to power up the LOW PASS
FILTER STAGE.
5. Select the 6.4 kHz sample rate—Bits FLD0 and FLD1 select the Low Pass filter setting and
sample rate to be used during record and playback. These are bits D2 and D3 of CFG1. To
enable the 6.4 kHz sample rate, D2 must be set to ONE and D3 set to ZERO.
6. Select the LOW PASS FILTER input (only) to the S2 SUMMING amplifier—Bits S2M0 and
S2M1 control the state of the SUM2 SUMMING amplifier. These are bits D5 and D6
respectively of CFG1 and they should be set to the state where D5 is ZERO and D6 is ONE to
select the LOW PASS FILTER (only) path.
In this mode, the elements of the original PASS THROUGH mode do not change. The sections of the
chip not required to add the record path remain powered down. In fact, CFG0 does not change and
remains
CFG0=0100 0100 0000 1011 (hex 440B).
CFG1 changes to
CFG1=0000 0000 1100 0101 (hex 00C5).
Since CFG0 is not changed, it is only necessary to load CFG1. Note that if only CFG0 was changed, it
would be necessary to load both registers.
7.3.9. Memo Record
The Memo Record mode sets the chip up to record from the local microphone into the chip’s Multilevel
Storage Array. A connected cellular telephone or cordless phone chip set may remain powered down
and is not active in this mode. The path to be used is microphone input to AGC amplifier, then through
the INPUT SOURCE MUX to the SUM1 SUMMING amplifier. From there the path goes through the
FILTER MUX, the LOW PASS FILTER, the SUM2 SUMMING amplifier, then to the MULTILEVEL
STORAGE ARRAY. In this instance, we will select the 5.3 kHz sample rate. The rest of the chip may
be powered down.
1. Power up the AGC amplifier—Bit AGPD controls the power up state of the AGC amplifier. This
is bit D0 of CFG1 and must be set to ZERO to power up this stage.
2. Select the AGC amplifier through the INPUT SOURCE MUX—Bit INS0 controls the state of
the INPUT SOURCE MUX. This is bit D9 of CFG0 and must be set to a ZERO to select the
AGC amplifier.
3. Select the INPUT SOURCE MUX (only) to the S1 SUMMING amplifier—Bits S1M0 and S1M1
control the state of the SUM1 SUMMING amplifier. These are bits D7 and D8 respectively of
CFG1 and they should be set to the state where D7 is ZERO and D8 is ONE to select the
INPUT SOURCE MUX (only) path.
4. Select the SUM1 SUMMING amplifier path through the FILTER MUX—Bit FLS0 controls the
state of the FILTER MUX. This is bit D4 of CFG1 and it must be set to ZERO to select the
SUM1 SUMMING amplifier path.
- 25 -
Publication Release Date: October, 2003
Revision 0.2
ISD5100 – SERIES
5. Power up the LOW PASS FILTER—Bit FLPD controls the power up state of the LOW PASS
FILTER stage. This is bit D1 of CFG1 and it must be set to ZERO to power up the LOW PASS
FILTER STAGE.
6. Select the 5.3 kHz sample rate—Bits FLD0 and FLD1 select the Low Pass filter setting and
sample rate to be used during record and playback. These are bits D2 and D3 of CFG1. To
enable the 5.3 kHz sample rate, D2 must be set to ZERO and D3 set to ONE.
7. Select the LOW PASS FILTER input (only) to the S2 SUMMING amplifier—Bits S2M0 and
S2M1 control the state of the SUM2 SUMMING amplifier. These are bits D5 and D6
respectively of CFG1 and they should be set to the state where D5 is ZERO and D6 is ONE to
select the LOW PASS FILTER (only) path.
To set up the chip for Memo Record, the configuration registers are set up as follows:
CFG0=0010 0100 0010 0001 (hex 2421).
CFG1=0000 0001 0100 1000 (hex 0148).
Only those portions necessary for this mode are powered up.
7.3.10. Memo and Call Playback
This mode sets the chip up for local playback of messages recorded earlier. The playback path is from
the MULTILEVEL STORAGE ARRAY to the FILTER MUX, then to the LOW PASS FILTER stage.
From there, the audio path goes through the SUM2 SUMMING amplifier to the VOLUME MUX,
through the VOLUME CONTROL then to the SPEAKER output stage. We will assume that we are
driving a piezo speaker element. This audio was previously recorded at 8 kHz. All unnecessary stages
will be powered down.
1. Select the MULTILEVEL STORAGE ARRAY path through the FILTER MUX—Bit FLS0, the
state of the FILTER MUX. This is bit D4 of CFG1 and must be set to ONE to select the
MULTILEVEL STORAGE ARRAY.
2. Power up the LOW PASS FILTER—Bit FLPD controls the power up state of the LOW PASS
FILTER stage. This is bit D1 of CFG1 and it must be set to ZERO to power up the LOW PASS
FILTER STAGE.
3. Select the 8.0 kHz sample rate—Bits FLD0 and FLD1 select the Low Pass filter setting and
sample rate to be used during record and playback. These are bits D2 and D3 of CFG1. To
enable the 8.0 kHz sample rate, D2 and D3 must be set to ZERO.
4. Select the LOW PASS FILTER input (only) to the S2 SUMMING amplifier —Bits S2M0 and
S2M1 control the state of the SUM2 SUMMING amplifier. These are bits D5 and D6
respectively of CFG1 and they should be set to the state where D5 is ZERO and D6 is ONE to
select the LOW PASS FILTER (only) path.
5. Select the SUM2 SUMMING amplifier path through the VOLUME MUX—Bits VLS0 and VLS1
control the state VOLUME MUX. These bits are bits D14 and D15, respectively of CFG1. They
should be set to the state where D14 is ONE and D15 is ZERO to select the SUM2 SUMMING
amplifier.

ISD5100 – SERIES
6. Power up the VOLUME CONTROL LEVEL—Bit VLPD controls the power-up state of the
VOLUME CONTROL attenuator. This is Bit D0 of CFG0. This bit must be set to a ZERO to
power-up the VOLUME CONTROL.
7. Select a VOLUME CONTROL LEVEL—Bits VOL0, VOL1, and VOL2 control the state of the
VOLUME CONTROL LEVEL. These are bits D11, D12, and D13, respectively, of CFG1. A
binary count of 000 through 111 controls the amount of attenuation through that state. In most
cases, the software will select an attenuation level according to the desires of the current
users of the product. In this example, we will assume the user wants an attenuation of –12 dB.
For that setting, D11 should be set to ONE, D12 should be set to ONE, and D13 should be set
to a ZERO.
8. Select the VOLUME CONTROL path through the OUTPUT MUX—These are bits D3 and D4,
respectively, of CFG0. They should be set to the state where D3 is ZERO and D4 is a ZERO
to select the VOLUME CONTROL.
9. Power up the SPEAKER amplifier and select the HIGH GAIN mode—Bits OPA0 and OPA1
control the state of the speaker (SP+ and SP–) and AUX OUT outputs. These are bits D1 and
D2 of CFG0. They must be set to the state where D1 is ONE and D2 is ZERO to power-up the
speaker outputs in the HIGH GAIN mode and to power-down the AUX OUT.
To set up the chip for Memo or Call Playback, the configuration registers are set up as follows:
CFG0=0010 0100 0010 0010 (hex 2422).
CFG1=0101 1001 1101 0001 (hex 59D1).
Only those portions necessary for this mode are powered up.
7.3.11. Message Cueing
Message cueing allows the user to skip through analog messages without knowing the actual physical
location of the message. This operation is used during playback. In this mode, the messages are
skipped 512 times faster than in normal playback mode. It will stop when an EOM marker is reached.
Then, the internal address counter will be pointing to the next message.

7.4.7. Analog Inputs
Microphone Inputs
The microphone inputs transfer the voice signal to the on-chip AGC preamplifier or directly to the ANA
OUT MUX, depending on the selected path. The direct path to the ANA OUT MUX has a gain of 6
dB so a 208 mV p-p signal across the differential microphone inputs would give 416 mV p-p across
the ANA OUT pins. The AGC circuit has a range of 45 dB in order to deliver a nominal 694 mV p-p
into the storage array from a typical electric microphone output of 2 to 20 mV p-p. The input
impedance is typically 10kΩ.
The ACAP pin provides the capacitor connection for setting the parameters of the microphone AGC
circuit. It should have a 4.7 µF capacitor connected to ground. It cannot be left floating. This is
because the capacitor is also used in the playback mode for the AutoMute circuit. This circuit reduces
the amount of noise present in the output during quiet pauses. Tying this pin to ground gives
maximum gain; to VCCA gives minimum gain for the AGC amplifier but will cancel the AutoMute
function.

7.5. DIGITAL MODE
7.5.1. Erasing Digital Data
The Digital Erase command can only erase an entire page at a time. This means that the D1
command only needs to include the 11-bit page address; the 5-bit for block address are left at 00000.
Once a page has been erased, each block may be written separately, 64 bits at a time. But, if a block
has been previously written then the entire page of 2048 bits must be erased in order to re-write (or
change) a block.
A sequence might be look like:
- read the entire page
- store it in RAM
- change the desired bit(s)
- erase the page
- write the new data from RAM to the entire page
7.5.2. Writing Digital Data
The Digital Write function allows the user to select a portion of the array to be used as digital memory.
The partition between analog and digital memory is left up to the user. A page can only be either
Digital or Analog, but not both. The minimum addressable block of memory in the digital mode is one
block or 64 bits, when reading or writing. The address sent to the device is the 11-bit row (or page)
address with the 5-bit scan (or block) address. However, one must send a Digital Erase before
attempting to change digital data on a page. This means that even when changing only one of the 32
blocks, all 32 blocks will need to be rewritten to the page. Command Sequence: The chip enters
digital mode by sending the ENTER DIGITAL MODE command from power down. Send the
DIGITAL WRITE @ ADDR command with the row address. After the address is entered, the data is
sent in one-byte packets followed by an I2C acknowledge generated by the chip. Data for each block
is sent MSB first. The data transfer is ended when the master generates an I2C STOP condition. If
only a partial block of data is sent before the STOP condition, “zero” is written in the remaining bytes;
that is, they are left at the erase level. An erased page (row) will be read as all zeros. The device can
buffer up to two blocks of data. If the device is unable to accept more data due to the internal write
process, the SCL line will be held LOW indicating to the master to halt data transfer. If the device
encounters an overflow condition, it will respond by generating an interrupt condition and an I2C Not
Acknowledge signal after the last valid byte of data. Once data transfer is terminated, the device
needs up to two cycles (64 us) to complete its internal write cycle before another command is sent. If
an active command is sent before the internal cycle is finished, the part will hold SCL LOW until the
current command is finished. After writing is complete, send the EXIT DIGITAL MODE command.
- 36 -
ISD5100 – SERIES
7.5.3. Reading Digital Data
The Digital Read command utilizes the combined I2C command format. That is, a command is sent to
the chip using the write data direction. Then the data direction is reversed by sending a repeated
start condition, and the slave address with R/W set to 1. After this, the slave device (ISD5100Series) begins to send data to the master until the master generates a NACK. If the part encounters
an overflow condition, the INT pin is pulled LOW. No other communication with the master is
possible due to the master generating ACK signals.
Digital Write and Digital Read can be done a “block” at a time.
each Digital Read command sequence.
Thus, only 64 bits need be read in
7.5.4. Example Command Sequences
An explanation and graphical representation of the Erase, Write and Read operations are found
below.
Note: All sequences assumes that the chip is in power-down mode before the commands are sent.

Notes
1. Erase operations must be addressed on a Row boundary. The 5 LSB bits of the Low Address
Byte will be ignored.
2. I2C bus is released while erase proceeds. Other devices may use the bus until it is time to
execute the STOP command that causes the end of the Erase operation.
3. Host processor must count RAC cycles to determine where the chip is in the erase process,
one row per RAC cycle. RAC pulses LOW for 0.25 millisecond at the end of each erased
row. The erase of the "next" row begins with the rising edge of RAC. See the Digital Erase
RAC timing diagram on page 51.
4. When the erase of the last desired row begins, the following STOP command (Command Byte
= 80 hex) must be issued. This command must be completely given, including receiving the
ACK from the Slave before the RAC pin goes HIGH at the end of the row.

7.6. PIN DETAILS
7.6.1. Digital I/O Pins
SCL (Serial Clock Line)
The Serial Clock Line is a bi-directional clock line. It is an open-drain line requiring a pull-up resistor
to Vcc. It is driven by the "master" chips in a system and controls the timing of the data exchanged
over the Serial Data Line.
SDA (Serial Data Line)
The Serial Data Line carries the data between devices on the I2C interface. Data must be valid on
this line when the SCL is HIGH. State changes can only take place when the SCL is LOW. This is
a bi-directional line requiring a pull-up resistor to Vcc.
RAC (Row Address Clock)
RAC is an open drain output pin that normally marks the end of a row. At the 8 kHz sample frequency,
the duration of this period is 256 ms. There are 2048 pages of memory in the ISD5116 devices, 1024
pages in the ISD5108, and 572 pages in the ISD5104. RAC stays HIGH for 248 ms and stays LOW
for the remaining 8 ms before it reaches the end of the page.

TRACL
The RAC pin remains HIGH for 500 µsec and stays LOW for 15.6 µsec under the Message Cueing
mode. See the Timing Parameters table on page 64 for RAC timing information at other sample
rates. When a record command is first initiated, the RAC pin remains HIGH for an extra TRACML period,
to load sample and hold circuits internal to the device. The RAC pin can be used for message
management techniques.

INT (Interrupt)
INT is an open drain output pin. The ISD5100 Series interrupt pin goes LOW and stays LOW when an
Overflow (OVF) or End of Message (EOM) marker is detected. Each operation that ends in an EOM or
OVF generates an interrupt, including the message cueing cycles. The interrupt is cleared by a READ
STATUS instruction that will give a status byte out the SDA line.
XCLK (External Clock Input)
The external clock input for the ISD5100 Series product has an internal pull-down device. Normally,
the ISD5100 Series are operated at one of four internal rates selected for its internal oscillator by the
Sample Rate Select bits. If greater precision is required, the device can be clocked through the XCLK
pin at 4.096 MHz as described in section 7.4.3 on page 32.
Because the anti-aliasing and smoothing filters track the Sample Rate Select bits, one must, for
optimum performance, maintain the external clock at 4.096 MHz AND set the Sample Rate
Configuration bits to one of the four values to properly set the filters to the correct cutoff frequency as
described in section 7.4.3 on page 32. The duty cycle on the input clock is not critical, as the clock is
immediately divided by two internally. If the XCLK is not used, this input should be connected to VSSD.

ISD5100 – SERIES
A0, A1 (Address Pins)
These two pins are normally strapped for the desired address that the ISD5100 Series will have on the
I2C serial interface. If there are four of these devices on the bus, then each must be strapped
differently in order to allow the Master device to address them individually. The possible addresses
range from 80h to 87h, depending upon whether the device is being written to, or read from, by the
host. The ISD5100 Series have a 7-bit slave address of which only A0 and A1 are pin
programmable. The eighth bit (LSB) is the R/W bit. Thus, the address will be 1000 0xy0 or 1000
0xy1. (See the table in section 7.3.1 on page 13.)
7.6.2. Analog I/O Pins
MIC+, MIC-
(Microphone Input +/-)
The microphone input transfers the voice signal to the on-chip AGC preamplifier or directly to the ANA
OUT MUX, depending on the selected path. The direct path to the ANA OUT MUX has a gain of 6 dB
so a 208 mV p-p signal across the differential microphone inputs would give 416 mV p-p across the
ANA OUT pins. The AGC circuit has a range of 45 dB in order to deliver a nominal 694 mV p-p into
the storage array from a typical electret microphone output of 2 to 20 mV p-p. The input impedance is
typically 10kΩ.

(Analog Output +/-)
This differential output is designed to go to the microphone input of the telephone chip set. It is designed to drive a minimum of 5 kΩ between the “+” and “–” pins to a nominal voltage level of 694 mV
p-p. Both pins have DC bias of approximately 1.2 VDC. The AC signal is superimposed upon this
analog ground voltage. These pins can be used single-ended, getting only half the voltage. Do NOT
ground the unused pin.
- 50 -
ISD5100 – SERIES
ACAP (AGC Capacitor)
This pin provides the capacitor connection for setting the parameters of the microphone AGC circuit. It
should have a 4.7 µF capacitor connected to ground. It cannot be left floating. This is because the
capacitor is also used in the playback mode for the AutoMute circuit. This circuit reduces the amount
of noise present in the output during quiet pauses. Tying this pin to ground gives maximum gain; tying
it to VCCA gives minimum gain for the AGC amplifier but cancels the AutoMute function.
SP +, SP-
(Speaker +/-)
This is the speaker differential output circuit. It is designed to drive an 8Ω speaker connected across
the speaker pins up to a maximum of 23.5 mW RMS power. This stage has two selectable gains, 1.32
and 1.6, which can be chosen through the configuration registers. These pins are biased to approximately 1.2 VDC and, if used single-ended, must be capacitively coupled to their load. Do NOT
ground the unused pin.
AUX OUT (Auxiliary Output)
The AUX OUT is an additional audio output pin to be used, for example, to drive the speaker circuit in
a “car kit.” It drives a minimum load of 5kΩ and up to a maximum of 1V p-p. The AC signal is
superimposed on approximately 1.2 VDC bias and must be capacitively coupled to the load.

ANA IN (Analog Input)
The ANA IN pin is the analog input from the telephone chip set. It can be switched (by the I2C
interface) to the speaker output, the array input or to various other paths. This pin is designed to
accept a nominal 1.11 V p-p when at its minimum gain (6 dB) setting. There is additional gain
available, if required, in 3 dB steps, up to 15 dB. The gain settings are controlled from the I2C
interface.

7.6.3. Power and Ground Pins
VCCA, VCCD (Voltage Inputs)
To minimize noise, the analog and digital circuits in the ISD5100 Series devices use separate power
busses. These +3 V busses lead to separate pins. Tie the VCCD pins together as close as possible and
decouple both supplies as near to the package as possible.
VSSA, VSSD (Ground Inputs)
The ISD5100 Series utilizes separate analog and digital ground busses. The analog ground (VSSA)
pins should be tied together as close to the package as possible and connected through a lowimpedance path to power supply ground. The digital ground (VSSD) pin should be connected through a
separate low impedance path to power supply ground. These ground paths should be large enough to
ensure that the impedance between the VSSA pins and the VSSD pin is less than 3Ω. The backside of
the die is connected to VSSD through the substrate resistance. In a chip-on-board design, the die
attach area must be connected to VSSD.
NC
(Not Connect)
These pins should not be connected to the board at any time. Connection of these pins to any signal,
ground or VCC, may result in incorrect device behavior or cause damage to the device.

1.
A Fast-mode I2C-interface device can be used in a Standard-mode I2C-interface system, but the
requirement tSU;DAT > 250 ns must then be met. This will automatically be the case if the device does not
stretch the LOW period of the SCL signal.
If such a device does stretch the LOW period of the SCL signal, it must output the next data bit to the SDA

line; tr max + tSU;DAT = 1000 + 250 = 1250 ns (according to the Standard-mode I C -interface specification)
before the SCL line is released.

Cb = total capacitance of one bus line in pF. If mixed with HS mode devices, faster fall-times are
allowed.

10.4. CHARACTERISTICS OF THE I2C SERIAL INTERFACE
The I2C interface is for bi-directional, two-line communication between different ICs or modules. The
two lines are a serial data line (SDA) and a serial clock line (SCL). Both lines must be connected to a
positive supply via a pull-up resistor. Data transfer may be initiated only when the interface bus is not
busy.
Bit transfer
One data bit is transferred during each clock pulse. The data on the SDA line must remain stable
during the HIGH period of the clock pulse, as changes in the data line at this time will be interpreted
as a control signal.

Start and stop conditions
Both data and clock lines remain HIGH when the interface bus is not busy. A HIGH-to-LOW transition
of the data line while the clock is HIGH is defined as the start condition (S). A LOW-to-HIGH transition
of the data line while the clock is HIGH is defined as the stop condition (P).

Example of an I C-bus configuration using two microcontrollers
Acknowledge
The number of data bytes transferred between the start and stop conditions from transmitter to
receiver is unlimited. Each byte of eight bits is followed by an acknowledge bit. The acknowledge bit is
a HIGH level signal put on the interface bus by the transmitter during which time the master generates
an extra acknowledge related clock pulse. A slave receiver which is addressed must generate an
acknowledge after the reception of each byte. In addition, a master receiver must generate an
acknowledge after the reception of each byte that has been clocked out of the slave transmitter.
The device that acknowledges must pull down the SDA line during the acknowledge clock pulse so
that the SDA line is stable LOW during the HIGH period of the acknowledge related clock pulse (setup and hold times must be taken into consideration). A master receiver must signal an end of data to
the transmitter by not generating an acknowledge on the last byte that has been clocked out of the
slave. In this event, the transmitter must leave the data line HIGH to enable the master to generate a
stop condition.

10.5. I2C PROTOCOL
Since the I2C protocol allows multiple devices on the bus, each device must have an address. This
address is known as a “Slave Address”. A Slave Address consists of 7 bits, followed by a single bit
that indicates the direction of data flow. This single bit is 1 for a Write cycle, which indicates the data is
being sent from the current bus master to the device being addressed. This single bit is a 0 for a Read
cycle, which indicates that the data is being sent from the device being addressed to the current bus
master. For example, the valid Slave Addresses for the ISD5100 Series device, for both Write and
Read cycles, are shown in section 7.3.1 on page 13 of this datasheet.
Before any data is transmitted on the I2C interface, the current bus master must address the slave it
wishes to transfer data to or from. The Slave Address is always sent out as the 1st byte following the
Start Condition sequence. An example of a Master transmitting an address to a ISD5100 Series slave
is shown below. In this case, the Master is writing data to the slave and the R/W bit is “0”, i.e. a Write
cycle. All the bits transferred are from the Master to the Slave, except for the indicated Acknowledge
bits. The following example details the transfer explained in section 7.3.1-2-3 on pages 13-20 of this
datasheet.

A common procedure in the ISD5100 Series is the reading of the Status Bytes. The Read Status
condition in the ISD5100 Series is triggered when the Master addresses the chip with its proper Slave
Address, immediately followed by the R/W bit set to a “1” and without the Command Byte being sent.
This is an example of the Master sending to the Slave, immediately followed by the Slave sending
data back to the Master. The “N” not-acknowledge cycle from the Master ends the transfer of data
from the Slave. The following example details the transfer explained in section 7.3.1 on page 13 of this
datasheet.

Another common operation in the ISD5100 Series is the reading of digital data from the chip’s memory
array at a specific address. This requires the I2C interface Master to first send an address to the
ISD5100 Series Slave device, and then receive data from the Slave in a single I2C operation. To
accomplish this, the data direction R/W bit must be changed in the middle of the command. The
following example shows the Master sending the Slave address, then sending a Command Byte and 2
bytes of address data to the ISD5100-Series, and then immediately changing the data direction and
reading some number of bytes from the chip’s digital array. An unlimited number of bytes can be read
in this operation. The “N” not-acknowledge cycle from the Master forces the end of the data transfer
from the Slave. The following example details the transfer explained in section 7.5.4 on page 47 of this
datasheet.
