DETAILED DESCRIPTION

SPEECH/SOUND QUALITY

The ISD MicroTAD-16M ChipCorder is offered at

4.0 KHz sampling frequency.
The speech samples are stored directly into on-

chip nonvolatile memory without the digitization
and compression associated with other solu­tions. Direct analog storage provides a natural
sounding reproduction of voice, music, tones,
and sound effects not available with most solid­state solutions.

FLASH STORAGE

One of the benefits of ISD’s ChipCorder technolo­gy is the use of on-chip nonvolatile 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 (typically) over 100,000 times.

MICROCONTROLLER INTERFACE

A four-wire (SCLK, MOSI, MISO, SS) SPI interface is
provided for ISD MicroTAD-16M control and ad­dressing functions. The ISD MicroTAD-16M is con­figured to operate as a peripheral slave device,
with a microcontroller-based SPI bus interface.
Read/Write access to all the internal registers oc­curs through this SPI interface. An interrupt signal
(INT

) and internal read-only Status Register are

provided for handshake purposes.

PROGRAMMING

The ISD MicroTAD-16M is also ideal for playback­only applications, where single or multiple mes­sage Playback is controlled through the SPI port.
Once the desired message configuration is creat­ed, duplicates can easily be generated via an
ISD programmer or a 3rd party programmer.

PIN DESCRIPTIONS

VOLTAGE INPUTS (V

CCA

, V

CCD

)

To minimize noise, the analog and digital circuits
in the ISD MicroTAD-16M device use separate pow­er busses. These +3 V busses are brought out to
separate pins and should be tied together as
close to the supply as possible. In addition, these
supplies should be decoupled as close to the
package as possible.

GROUND INPUTS (V

SSA

, V

SSD

)

The ISD MicroTAD-16M utilizes separate analog
and digital ground busses. The analog ground
(V

SSA

) pins should be tied together as close to
the package as possible and connected
through a low-impedance path to power supply
ground. The digital ground (V

SSD

) 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 V

SSA

pins and the V

SSD

pin is less than 3 Ω . The backside of the die is con­nected to V

SS

through the substrate resistance.
In a chip-on-board design, the die attach area
must be connected to V

SS

or left floating.

NON-INVERTING ANALOG INPUT (ANA IN+)

This pin is the non-inverting analog input that
transfers the signal to the device for recording.
The analog input amplifier can be driven single
ended or differentially. In the single-ended input
mode, a 32 mVp-p (peak-to-peak) maximum sig­nal should be capacitively connected to this pin
for optimal signal quality. This capacitor value,
together with the 3 K

Ω

input impedance of ANA
IN+, is selected to give cutoff at the low frequen­cy end of the voice passband. In the differential­input mode, the maximum input signal at ANA
IN+ should be 16 mVp-p for optimal signal quali­ty. The circuit connections for the two modes are
shown in Figure 2 on page 2.

INVERTING ANALOG INPUT (ANA IN–)

This pin is the inverting analog input that transfers
the signal to the device for recording in the dif­ferential-input mode. In this differential-input
mode, a 16 mVp-p maximum input signal at
ANA IN– should be capacitively coupled to this
pin for optimal signal quality as shown in the ISD
MicroTAD-16M ANA IN Modes, Figure 2. This ca­pacitor value should be equal to the coupling
capacitor used on the ANA IN+ pin. The input im­pedance at ANA IN– is nominally 56 K

Ω

. In the sin­gle-ended mode, ANA IN– should be
capacitively coupled to V

SSA

through a capaci-

tor equal to that used on the ANA IN+ input.

AUDIO OUTPUT (AUD OUT)

This pin provides the audio output to the user.
It is capable of driving a 5 K

Ω

impedance. It is

recommended that this pin be AC coupled.

NOTE

The AUDOUT pin is always at 1.2 volts when
the device is powered up. When in play­back, the output buffer connected to this
pin can drive a load as small as 5 K

Ω

. When
in record, a resistor connects AUDOUT to
the internal 1.2 volt analog ground supply.
This resistor is approximately 850 K

Ω

. This rel­atively high impedance allows this pin to
be connected to an audio bus without
loading it down.

SLAVE SELECT (SS

)

This input, when LOW, will select the ISD Mi­croTAD-16M device.

MASTER OUT SLAVE IN (MOSI)

This is the serial input to the ISD MicroTAD-16M
device. The master microcontroller places data
on the MOSI line one half-cycle before the rising
clock edge to be clocked in by the ISD Micro­TAD-16M device.

MASTER IN SLAVE OUT (MISO)

This is the serial output of the ISD MicroTAD-16M
device. This output goes into a high-impedance
state if the device is not selected.

SERIAL CLOCK (SCLK)

This is the clock input to the ISD MicroTAD-16M. It
is generated by the master device (microcon­troller) and is used to synchronize data transfers
in and out of the device through the MISO and
MOSI lines. Data is latched into the ISD MicroTAD­16M on the rising edge of SCLK and shifted out of
the device on the falling edge of SCLK.

INTERRUPT (INT

)

The ISD MicroTAD-16M interrupt pin goes LOW
and stays LOW when an Overflow (OVF) or End
of Message (EOM) marker is detected. This is an
open drain output pin. Each operation that ends
in an EOM or Overflow will generate an interrupt
including the message cueing cycles. The inter­rupt will be cleared the next time an SPI cycle is
initiated. The interrupt status can be read by an
RINT instruction.

Overflow Flag (OVF)

—The Overflow flag indi­cates that the end of the ISD MicroTAD-16M’s
analog memory has been reached during a
record or playback operation.

End of Message (EOM)

—The End-of-Message
flag is set only during playback operation when
an EOM is found. There are eight EOM flag posi­tion options per row.

ROW ADDRESS CLOCK (RAC)

This is an open drain output pin that provides a
signal with a 400 ms period at the 4 KHz sampling
frequency. (This represents a single row of memo­ry and there are 2400 rows of memory in the ISD
MicroTAD-16M devices.) This signal stays HIGH for
350 ms and stays LOW for 50 ms when it reaches
the end of a row.

The RAC pin stays HIGH for 218.76

µ

sec and stays

LOW for 31.26

µ

sec in Message Cueing mode
(see page 5 for a more detailed description of
Message Cueing). Refer to the AC Parameters
table for RAC timing information on other sam­ple rate products.

When a record command is first initiated, the
RAC pin remains HIGH for an extra T

RACLO

period.
This is due to the need to load sample and hold
circuits internal to the device. This pin can be
used for message management techniques.

EXTERNAL CLOCK INPUT (XCLK)

The external clock input for the ISD MicroTAD­16M product has an internal pull-down device.
These products are configured at the factory
with an internal sampling clock frequency cen­tered to ±1 percent of specification. The fre­quency is then maintained to a variation over
the entire commercial temperature and oper­ating voltage ranges as defined by the min­imum/maximum limits in the applicable AC
Parameters table. The internal clock has a toler­ance, over the extended temperature, industrial
temperature and voltage ranges as defined by
the minimum/maximum limits in the applicable
AC Parameters table. A regulated power supply
is recommended for industrial temperature
range parts. If greater precision is required, the
device can be clocked through the XCLK pin in
Table 1.

This recommended clock rate should not be var­ied because the antialiasing and smoothing filters
are fixed. Thus, 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 inter­nally.

If the XCLK is not used, this input should be

connected to ground.

AUTOMUTE™ FEATURE (AM CAP)

This pin is used in controlling the AutoMute fea­ture. The AutoMute feature attenuates the signal
when it drops below an internally set threshold.
This helps to eliminate noise (with 6 dB of attenu­ation) when there is no signal (i.e., during periods
of silence). A 1

µ

F capacitor to ground should be
connected to the AM CAP pin. This capacitor
becomes a part of an internal peak detector
which senses the signal amplitude (peak). This
peak level is compared to an internally set
threshold to determine the AutoMute trip point.
For large signals the AutoMute attenuation is set
to 0 dB while 6 dB of attenuation occurs for
silence. The 1

µ

F capacitor also affects the rate
at which the AutoMute feature changes with the
signal amplitude (or the attack time). The Auto­mute feature can be disabled by connecting
the AM CAP pin to V

CCA

.

SERIAL PERIPHERAL INTERFACE (SPI) DESCRIPTION

The ISD MicroTAD-16M operates from an SPI serial
interface. The SPI interface operates with the fol­lowing protocol.

The data transfer protocol assumes that the mi­crocontroller’s SPI shift registers are clocked on
the falling edge of the SCLK. With the ISD Micro­TAD-16M, data is clocked in on the MOSI pin on
the rising clock edge. Data is clocked out on the
MISO pin on the falling clock edge.

1.

All serial data transfers begin with the fall­ing edge of SS

pin.

2.

SS is held LOW during all serial communica­tions and held HIGH between instructions.

3.

Data is clocked in on the rising clock edge
and data is clocked out on the falling
clock edge.

4.

Play and Record operations are initiated
by enabling the device by asserting the SS
pin LOW, shifting in an opcode and an
address field to the ISD MicroTAD-16M de­vice (refer to the Opcode Summary on
the page 6).

5.

The opcodes and address fields are as fol­lows: <8 control bits> and <16 address
bits>.

6.

Each operation that ends in an EOM or
Overflow will generate an interrupt, in­cluding the Message Cueing cycles. The
Interrupt will be cleared the next time an
SPI cycle is initiated.

7.

As Interrupt data is shifted out of the ISD
MicroTAD-16M MISO pin, control and ad­dress data is simultaneously being shifted
into the MOSI pin. Care should be taken
such that the data shifted in is compatible
with current system operation. It is possible
to read interrupt data and start a new op­eration within the same SPI cycle.

8.

An operation begins with the RUN bit set
and ends with the RUN bit reset.

9.

All operations begin with the rising edge
of SS

.

MESSAGE CUEING

Message cueing allows the user to skip through
messages, without knowing the actual physical
location of the message. This operation is used
during playback. In this mode, the messages are
skipped 1600 times faster than in normal play­back mode. It will stop when an EOM marker is
reached. Then, the internal address counter will
point to the next message.

If you are utilizing the Message Cueing Com­mand, you must perform the following Message
Cueing procedure to ensure proper Message
Cueing for the MicroTAD product. Failure to fol­low this procedure may result in inaccurate Mes­sage Cueing.

Procedure for Proper Message Cueing:
A single “dummy” STOP command must be sent

to the device before executing a Message Cue­ing (MC) or SET Message Cueing (SET MC) In­struction.

The “dummy” STOP instruction consists of a com­mand with control bits set as follows:

RUN bit = 0
PLAY/RECORD bit = 0
PU bit = 1
IAB bit = 1
MC bit = 0

That is, a hex “30” is shifted into the device as a
command.

One or more MC or SET MC commands may be
executed following this command. It is not nec­essary to repeat the “dummy” STOP command
until after a subsequent playback operation.

Voice Solutions in Silicon

™

1.

Message Cueing can be selected only at the beginning of a play operation.

2.

As the Interrupt data is shifted out of the ISD MicroTAD-16M, control and address data is being shifted in. Care should
be taken such that the data shifted in is compatible with current system operation. It is possible to read interrupt
data and start a new operation at the same time. See Figure 5 through Figure 8 for Opcode format.

POWER-UP SEQUENCE

The ISD MicroTAD-16M will be ready for an oper­ation after T

PUD

(50 ms approximately for 4 KHz

sample rate). The user needs to wait T

PUD

before is­suing an operational command. For example, to
play from address 00 the following programing
cycle should be used.

Playback Mode

1. Send POWERUP command.

2.

Wait T

PUD

(power-up delay).

3.

Send SETPLAY command with address 00.

4.

Send PLAY command.

The device will start playback at address 00 and
it will generate an interrupt when an EOM is
reached. It will then stop playback.

Record Mode

1.

Send POWERUP command.

2.

Wait T

PUD

(power-up delay).

3.

Send POWERUP command.

4.

Send SETREC command with address 00.

5.

Send REC command.

The device will start recording at address 00 and
it will generate an interrupt when an overflow is
reached (end of memory array). It will then stop
recording.
