FUNCTIONAL DESCRIPTION
O
The I5216 ChipCorder Product provides high quality, fully integrated, single-chip Record/Playback
solutions for 8- to 16-minute messaging applications that are ideal for use in PBX systems, cellular
phones, automotive communications, GPS/navigation systems, and other portable products. The I5216
product is an enhancement to the ISD5116 architecture, providing: 1) A full duplex Voice CODEC with
2
µ-Law and A-Law compander, with I S and PCM interface ports; 2) A 2.2V microphone bias supply for
reduced noise coupling. This supply can also be used to power down the external microphone with the
system.
Analog functions and audio gating have also been integrated into the I5216 product to allow for easy
interfacing with integrated chip sets on the market. Audio paths have been designed to enable full
duplex conversation record, voice memo and answering machine (including outgoing message
playback).
Logic Interface Options of 2.0V and 3.0V are supported by the I5216 to accommodate both portable
communication (2.0- and 3.0-volt required) and automotive product customers (5.0-volt required).
Like other ChipCorder products, the I5216 integrates the sampling clock, anti-aliasing and smoothing
filters, and multi-level storage array on a single chip. For enhanced voice features, the I5216 eliminates
external circuitry by integrating automatic gain control (AGC), a power amplifier/speaker driver, volume
control, summing amplifiers, analog switches, and a Voice CODEC. Input level adjustable amplifiers
are also included, providing a flexible interface for multiple applications.
Recordings are stored in 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 voice and music reproduction.
SPEECH/SOUND QUALITY
The I5216 ChipCorder product can be configured, via software, to operate at 4.0, 5.3, 6.4, and 8.0 kHz
sampling frequencies, allowing the user a choice of speech quality options. Increasing the duration
decreases the sampling frequency and bandwidth, which affects sound quality. The "Input Sample
Duration" table below compares filter pass band and product durations.
DURATION
To meet end-system requirements, the I5216 device is a single-chip solution, which provides 8 to 16
minutes of voice record and playback, depending on the sample rates defined by the customer's
software.

FLASH STORAGE
One of the benefits of Winbond’s ChipCorder technology is the use of on-chip nonvolatile memory,
which provides zero-power message storage. A 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 digital
messages and over 100,000 times (typically) for analog messages.
A new feature has been added that allows for the allocation of memory space in the I5216, to either
digital or analog storage, when recording. When making a recording, if a section is assigned for digital
or analog data storage, the system microcontroller stores this information in the Message Address
Table.
MICROCONTROLLER INTERFACE
2
The I5216 is controlled through an I C 2-wire interface. This synchronous serial port allows commands,
configurations, address data, and digital data to be loaded to 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 pins can be connected to the microcontroller for enhanced interface: the RAC
timing pin and the INT\ pin for interrupts to the controller. Communications with all of the internal
registers is through the serial bus, as well as digital memory Read and Write operations.
PROGRAMMING
The I5216 series is also ideal for playback-only applications, whereas single or multiple messages may
2
be played back when desired. Playback is controlled through the I C port. Once the desired message
configuration is created, duplicates can easily be generated via a Winbond or third-party programmer.
For more information on available application tools and programmers, please see the Winbond web
site at http://www.winbond-usa.com/.
APPLICATIONS
The I5216 is a single chip solution for voice and analog storage that also includes the capability to
store digital information in the memory array. The array may be divided between analog and digital
storage, as the user chooses, when configuring the device.
Looking at the block diagram on the following page, one can see that the I5216 may be very easily
designed into a cellular phone. Placing the device between the microphone and the existing baseband
chip takes care of the transmit path. The SDI/SDIO of the baseband chip is connected to the SDIO/SDI
2
of the I5216. Two pins are needed for the I C digital control and digital information for storage.

Starting at the MICROPHONE inputs, the input signal at the MICROPHONE inputs can be routed in
the following ways:
•
directly through the Voice band CODEC of the I5216 chip, then through the SDIO pin, to output
the digital PCM signal.
•
through the AGC amplifier, before it is routed to the voice band CODEC.
•
through the AGC amplifier to the storage array
•
through the AGC amplifier and mixed with an analog voice band CODEC signal coming from
the digital SDI pin
In addition, if the phone is inserted into a "hands-free" car kit, then the signal from the pickup
microphone in the car can be passed through to the same places from the AUX IN pin and the phone's
microphone is switched off. In this scenario, the other party's voice from the phone would be played
into the PCM IN input and passed through to the AUX OUT pin that would drive the car kit's
loudspeaker.
Depending upon whether one desires recording one side (simplex) or both sides (duplex) of a
conversation, the various paths will also be switched through to the low pass filter (for antialiasing) and
into the storage array. Later, the cell phone owner can play back the messages from the array. When
this happens, the Array Output MUX is connected to the volume control, through the Output MUX, to
the Speaker Amplifier. For applications other than a cell phone, the audio paths can be switched into
many different and flexible configurations. Some examples follow.

MEMORY ORGANIZATION
The I5216 memory array is arranged as 1888 rows (or pages) of 2048 bits, for a total memory of
3,866,624 bits. The primary addressing for the 2048 pages is handled by 11 bits of address data in the
analog mode. At the 8 kHz sample rate, each page contains 256 milliseconds of audio. Thus, at 8 kHz
there is actually room for 8 minutes and 3 seconds of audio.
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 (op code) at the time
the data is written. A record of what is analog and what is digital, and where, is stored by the system
microcontroller in the message address table (MAT). The MAT is a table kept in the microcontroller
memory that defines the status of each message “block.” It can be stored back into the I5216 if the
power fails or the system is turned off. Use of this table allows for 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 Winbond I5008 in Applications Note #No.9 and will similarly be in a later
Note for the I5216.]
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, 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 issued, but continues until the 32-millisecond block is filled. Then a bit is placed
into the EOM memory to develop the interrupt that signals a message is finished playing in the
Playback mode.
2
Digital data is sent and received, serially, over the I C 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
acknowledgement. If data is coming in faster than it can be written, then the chip will not issue an
acknowledgement to the host microcontroller until it is ready.
The read mode is the opposite of the write mode. Data is read into one of two 64-bit registers from the
2
array and serially sent to the I C port. (See Digital Mode on page 41 for details).

I2C SLAVE ADDRESS
The I5216 has a 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 eight possible slave addresses for the I5216

I2C OPERATION DEFINTIONS
There are many control functions used to operate the I5216. Among them are the following.
2
Conventions used in I C Data
Transfer Diagrams
READ STATUS COMMAND: The read status command is a read
request from the Host processor to the I5216 without delivering a
Command Byte. The Host supplies all of the clocks (SCL). In each
case, the entity sending the data drives the data line (SDA). The Read
2
Status Command is executed by the following I C sequence.
S
= START Condition
P
= STOP Condition
2
1. Host executes I C START
2. Send Slave Address with R/W bit = “1” (Read) 81h.
DATA = 8 bit data transfer
3. Slave responds back to Host an Acknowledge (ACK), followed
by 8 bit Status word.
R
= “1” in the R/W bit
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.
A

I2C CONTROL REGISTERS
The I5216 is controlled by loading commands to, or reading commands 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 I5216 is implemented through an 8-bit command byte that is 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

DATABYTES
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,
2
as specified by the I C 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>
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 is the upper address byte and the last is 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>
The lower address byte will always return the block address bits as zero, either in digital or analog
mode.
The functions of the bits are:
BIT#

EOM
Indicates whether an EOM interrupt has occurred.
6
OVF

5
READY
Indicates the internal status of the device – if READY is LOW no new
commands should be sent to device.
4
PD
Device is powered down if PD is HIGH.
3
PRB
Play/Record mode indicator. HIGH=Play/LOW=Record.
DEVICE_ID
An internal device ID. This is 001 for the I5216.

It is good practice to 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, the controller does not have to poll as frequently to determine the status of the I5216

PLAYBACK MODE
The command sequence for an analog Playback operation can be handled several ways. One
technique is to do a Load Address (81h), which requires sending a total of four bytes, followed by a
Play Analog, which is a Command Byte (A8h) preceded by the Slave Address Byte. This is a total of six
bytes plus the times for Start, ACK, and Stop.
Another approach for an analog Playback operation is via 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.
RECORD MODE
The command sequence for an Analog Record is a four byte sequence consisting of the Slave
Address (80h), the Command Byte (91h) for Record Analog @ Address, and the two address bytes.

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 three 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 I5216 to connect to a cellular or cordless baseband 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 digital audio input on the
baseband chip set. The receive path connects the baseband chip set’s digital output through to the
speaker driver on the Winbond chip. This allows the Winbond chip to substitute for Analog to Digital
and Digital to Analog conversion, and incidentally gain access to the audio, both to and from the
baseband chip set.
To setup the environment described above, a series of commands need to be sent to the I5216. First,
the chip needs to be powered up as described in Power-Up Sequence on page 25. Then the
Configuration Registers need to be filled with the specific data to connect the desired paths. In the
case of the Feed Through Mode, most of the chip can remain powered down. The Feed Through
Mode diagram illustrates the affected paths
To select the Feed Through mode, the following control bits must be configured in the I5216 configuration register
To set up the transmit path:
1. Select the FTHRU path through the CODEC INPUT MUX—Bits CDI1 and CDI0 control the
state of the CODEC INPUT MUX. These are the D6 and D5 bits, respectively, of Configuration
Register 0 (CFG0) and they should be set to ONE and ZERO, respectively, to select the
FTHRU path.
2. Power up the ADC—Bit ADPD controls the power up state of ADC. This is bit D0 of CFG2 and
it should be a ZERO to power up the ADC.
3. Set the CODEC input gain. The input gain setting will depend on the input level at the MIC+/pins and can be set by the CODEC INPUT GAIN Bits CIG2, CIG1 and CIG0. These are the
D15, D14 and D13 bits, respectively, of Configuration Register 0 (CFG0). The input gain can
be set according to the following table. (Table A)
4. Enable the High Pass Filter, if desired, in the low sample rate mode. This can be done by
setting bit HPF0 to ONE. This is bit D6 of CFG2.
5. Select the low or high sample rate mode by setting bit HSR0. This is bit D5 of CFG2. HSR0
needs to be set to ONE for the high sample rate mode.
6. Set the MUTE bit if desired. This bit can be set temporarily to reduce power up ‘pops’ or to set
the system on hold. This bit is D7 of CFG2 and needs to be set to ONE in order to mute the
signal.
7. Set the digital data format through bits LAW1 and LAW0. These are bits D3 and D2 of CFG2,
respectively. The data format can be chosen according to the following table. (Table B).

1. Power up the DAC—Bit DAPD controls the power up state of the DAC. This is bit D1 of CFG2
and should be a ZERO to power up the DAC.
2. Select the DAC 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 DAC path.
3. 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 a higher gain setting (for use with a piezo speaker element) and also powers down the
AUX output stage.

4. Set the Master Clock configuration bits and bits HSR0, MUTE, HPF0, I S0, LAW1 and LAW0
as described in the previous sections.
The status of the rest of the functions in the I5216 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 internal oscillator—Bit PDOS controls the power up state of the internal
ChipCorder oscillator. This is bit D8 of CFG0 and it should be set to a ONE to power down this
oscillator

3. 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.
4. 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 four bits should be set to a ONE in order to power down these
two amplifiers.
5. 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.
6. 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.
7. Don’t Care bits—All other bits are not used in Feed Through Mode. Their bits may be set to either
level. In this example, we will set all the "Don’t Care" bits to a ZERO.
The following example shows the setup for a full-duplex feed-through path at 8 kHz sampling rate. The
twos complement data format is enabled. The High Pass filter is also enabled. The Master Clock input
is running at 13.824MHz.
CFG0=0010 0101 0100 1011 (hex 254B)
and
CFG1=0000 0001 1110 0011 (hex 01E3).
and
CFG2=0000 0000 0100 0000 (hex 0040).
Since three registers are being loaded, CFG0 is loaded, followed by the loading of CFG1 and CFG2.
These three registers must be loaded in this order. The internal set up for these registers will take
effect synchronously, with the rising edge of SCL.
CALL RECORD
The call record mode adds the ability to record the incoming phone call. In most applications, the I5216
would first be set up for Feed Through Mode as described above. When the user wishes to record the
incoming call, the set up of the chip is modified to add that ability. For the purpose of this
explanation, we will use the 6.4 kHz ChipCorder sample rate during recording.
The block diagram of the I5216 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, back to the origin CODEC. Feed
Through Mode has already powered up the CODEC, so we only need to power up and enable the path
to the Multilevel Storage array from that point:

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
since they are not active in this mode. The path to be used is microphone input to AGC amplifier, then
through to 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 example, we will select the 5.3 kHz sample rate. The rest of
the chip may be powered down.

MEMO AND CALL PLAYBACK
This mode sets the chip up for local playback of messages that were 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

AUTO MUTE AND AUTO GAIN FUNCTIONS
During playback, the signal passes through the Automatic Attenuator before it is filtered. The
Automatic Attenuator will attenuate all signals at the noise level in order to reduce the noise during
quiet pauses.
During record, low level input signals are brought up by the Auto Gain function if the configuration bit
D7 of CFG0 (AMT0) is set. This improves the signal to noise ratio of recorded low level input signals. If
the configuration bit CFG0<7> (AMT0) is set to ZERO, all input levels are recorded with the same gain
setting. The attack and release time of the Auto Gain and Auto Mute functions is set by the capacitor
on the ACAP pin. The AGC cannot be used if the Auto Gain or Auto Mute function is enabled.

MICROPHONE INPUTs
The microphone inputs transfer the voice signal to the on-chip AGC preamplifier, or directly to the
CODEC INPUT MUX, depending on the selected path. 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.
The MICBS pin provides a 2.2V bias voltage for the external microphone only when the AGC is
powered up. Using this regulated bias voltage results in less supply noise coupling into the MIC+ and
MIC- pins compared to the situation in which the external microphone is powered up through the power
supply. It also saves current during power down.
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 or when signal compression is
chosen (AMT0 set). The AutoMute circuit reduces the amount of noise present in the output during
quiet pauses. Tying the ACAP pin to ground gives maximum gain. Tying it to VCCA gives minimum
gain for the AGC amplifier, but cancels the AutoMute function.

DIGITAL MODE
In the Digital Mode, it is important to understand that each group of digital operations must be
preceded by the Digital Mode command (0XC0) and followed by the Exit Digital Mode command
(0X40). No delay is required after these commands. Note that after any of these operations is
completed, the device is powered down. Therefore, it will be required to issue the normal Power-Up
command (0X80h) with a power-up delay (Tpud) before any analog operations can be performed
following digital commands.
WRITING 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 1 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
will need to be rewritten to the page.
2
After the address is entered, the data is sent in one-byte packets followed by an I C acknowledge
generated by the chip. Data for each block is sent MSB first. The data transfer is ended when the
2
master generates an I C 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
2
will respond by generating an interrupt condition and an I C 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 I5216 will hold SCL LOW until the current command is finished.
READING DATA
2
The Digital Read command utilizes the combined I C 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 one. After this, the slave device (I5216) begins to send
data to the master until the master generates a Not Acknowledge. 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.
As with Digital Write, Digital Read can be done a “block” at a time. Thus, only 64 bits need to be read
in each Digital Read command sequence.
ERASING DATA
The Digital Erase command can only erase an entire page at a time. This means that the D0 or 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.

Notes:
1. Erase operations must be addressed on a Row boundary. The 5 LSB bits of the Low
Address Byte will be ignored.
2
2. I C 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 microsecond 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 46.
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 .25 microseconds before
the end of the row.
PIN DETAILS
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)
2
The Serial Data Line carries the data between devices on the I C 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 bidirectional 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 1888 pages of memory in the Winbond I5216 device.
RAC stays HIGH for 248 ms and goes LOW for the remaining 8 ms before it reaches the end of the
page.

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 55 for RAC timing information at other sample rates.
When a record command is first initiated, the RAC pin remains HIGH for an extra TRACLO period in
order 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 Winbond I5216 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 gives a status byte out the SDA line.
MCLK (Master Clock Input)
The Master clock input for the Winbond I5216 product has an internal pull-down device. Normally, the
Winbond I5216 ChipCorder section is operated at one of four internal rates selected for its internal
oscillator by the Sample Rate Select bits. If the internal oscillator is powered down (configuration bit
OSPD set to ONE), the device is clocked through the MCLK pin as shown in the section I5216 Analog
Structure (right half) description on page 36.

Because the anti-aliasing and smoothing filters track the Sample Rate Select bits, one must, for
optimum performance, maintain the external clock at one of the four possible frequencies shown in the
table for Analog Structure (Right Half) description on page 36 AND set the Sample Rate Configuration
bits to one of the four values in order to properly set the filters to their correct cutoff frequency as
described in Analog Structure (Right Half) description on page 36. The duty cycle on the input clock is
not critical when CKD2 is set to ONE, as the clock is immediately divided by two (internally). If the
MCLK is not used, this input should be connected to VSSD.
A0, A1 (Address Pins)
These two pins are normally strapped for the desired address that the Winbond I5216 will have on the
2
I C 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 Winbond I5216 has 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

VCCA, VCCD (Voltage Inputs)
To minimize noise, the analog and digital circuits in the Winbond I5216 device 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 Winbond I5216 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 (No 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.

A Fast-mode I C-interface device can be used in a Standard-mode I C-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
2
I C -interface specification) before the SCL line is released.

I2C SERIAL INTERFACE TECHNICAL INFORMATION
CHARACTERISTICS OF THE I2C SERIAL INTERFACE
2
The I C 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)

SYSTEM CONFIGURATION
A device generating a message is a ‘transmitter’; a device receiving a message is the ‘receiver’. The
device that controls the message is the ‘master’ and the devices that are controlled by the master are
the ‘slaves’.
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.

Since the I C 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.
2
Before any data is transmitted on the I C interface, the current bus master must address the slave it
st
wishes to transfer data to or from. The Slave Address is always sent out as the 1 byte following the
Start Condition sequence. An example of a Master transmitting an address to a ISD5216 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.

A common procedure in the ISD5116 is the reading of the Status Bytes. The Read Status condition in
the ISD5216 is triggered when the Master addresses the chip with its proper Slave Address,
immediately followed by the R/W bit set to a “0” 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.

PRELIMINARY
Another common operation in the ISD5216 is the reading of digital data from the chip’s memory array
2
at a specific address. This requires the I C interface Master to first send an address to the ISD5116
2
Slave device, and then receive data from the Slave in a single I C 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 ISD5216, 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” notacknowledge cycle from the Master forces the end of the data transfer from the Slave. The following
example details the transfer explained in the section on page 41 of this datasheet.

I2S SERIAL INTERFACE TECHNICAL INFORMATION
2
THE I BUS
As shown in the following figure, the bus has three lines:
• continuous serial clock (SCK)
• word select (WS)
• serial data (SD)and the device generating SCK and WS is the master.
Simple System Configurations and Basic Interface Timing
SERIAL DATA
Serial data is transmitted in two’s complement with the MSB first. The MSB is transmitted first because
the transmitter and receiver may have different word lengths. It isn’t necessary for the transmitter to
know how many bits the receiver can handle, nor does the receiver need to know how many bits are
being transmitted.
When the system word length is greater than the transmitter word length, the word is truncated (least
significant data bits are set to ‘0’) for data transmission. If the receiver is sent more bits than its word
length, the bits after the LSB are ignored. On the other hand, if the receiver is sent fewer bits than its
word length, the missing bits are set to zero internally. And so, the MSB has a fixed position, whereas
the position of the LSB depends on the word length. The transmitter always sends the MSB of the next
word one clock period after the WS changes.

Advanced Information
PRELIMINARY
Serial data sent by the transmitter may be synchronized with either the trailing (HIGH-to-LOW) or the
leading (LOW-to-HIGH) edge of the clock signal. However, the serial data must be latched into the
receiver on the leading edge of the serial clock signal, and so there are some restrictions when
transmitting data that is synchronized with the leading edge (see figure below ).
Note that the specifications are defined by the transmitter speed. The specification of the receiver has to be able
to match the performance of the transmitter.

WORD SELECT
The word select line indicates the channel being transmitted:
• WS = 0; channel 1 (left)
• WS = 1; channel 2 (right)
WS may change either on a trailing or leading edge of the serial clock, but it doesn’t need to be
symmetrical. In the slave, this signal is latched on the leading edge of the clock signal. The WS line
changes one clock period before the MSB is transmitted. This allows the slave transmitter to derive
synchronous timing of the serial data that will be set up for transmission. Furthermore, it enables the
2
receiver to store the previous word and clear the input for the next word (see figure Timing for I S
Transmitter on previous page.)
TIMING
2
In the I S format, any device can act as the system master by providing the necessary clock signals. A
slave will usually derive its internal clock signal from an external clock input. This means, taking into
account the propagation delays between master clock and the data and/or word-select signals, that the
total delay is simply the sum of:
• the delay between the external (master) clock and the slave’s
internal clock; and
• the delay between the internal clock and the data and/or
word-select signals.
For data and word-select inputs, the external to internal clock delay is of no consequence because it
2
only lengthens the effective set-up time (see figure Timing for I S Transmitter on previous page.) The
major part of the time margin is to accommodate the difference between the propagation delay of the
transmitter, and the time required to set up the receiver.
All timing requirements are specified relative to the clock period or to the minimum allowed clock
period of a device. This means that higher data rates can be used in the future.
Timing for I2S Receiver
T
= clock period
TR = minimum allowed clock period for transmitter
T > TR
Note that the specifications are defined by the transmitter speed. The specification of the receiver has to be able
to match the performance of the transmitter.
