Note(s) and/or Footnote(s):
1. VEXT is rectified RF voltage, for power supply of external circuits. It is limited to 3.4V, when enough signal is present on the coil. The
maximum output current is 5mA and is dependent on the strength of the RF field.
2. Limits are 100% production tested at TA = 35°C. Limits over the operating temperature range are guaranteed by design.
3. During calibration on wafer sort, the chuck temperature variation is ±0.5°C, which amounts to the major part of the accuracy error.
4. The real time oscillator frequency is trimmed on wafer sort at 35°C.

SL13A – 7
Detailed Description
Detailed Description
The SL13A is designed for use in smart active labels (SAL) and
smart passive labels. Smart active labels are defined as thin and
flexible labels that contain an integrated circuit and a power
source. SAL includes in its definition both “fully active” smart
labels, and semi-active smart labels, also known as
battery-assisted back-scattered passive labels, both of which
enable enhanced functionality and superior performance over
existing passive labels. The SL13A can be used in semi-active or
fully-passive smart labels. The IC includes sensor functionality
and logging of sensor data (see Figure 1 below).
The SL13A is operating at 13.56 MHz and is fully ISO 15693
compliant. The chip is supplied from a single-cell battery of
typically 1.5V. The on-chip temperature sensor and real-time
clock (RTC) accommodate temperature data logging.
Supply Arrangement
The SL13A is supplied from either the battery or through the
electromagnetic waves from a reader. The device is normally
supplied from the battery unless the battery voltage is too low
- in this case the device is powered from the RF field. This
functionality enables the read out of the log data even in case
the battery is exhausted.
The chip automatically detects whether a 1.5V or 3V battery is
connected and adapts accordingly. The voltage step-up
converter provides an input voltage for the voltage regulator,
which provides a regulated voltage of 2V nominal (internal
digital supply). The maximum current available from V EXT for
external circuitry is 4mA (only when RF field is present) and is
limited to 3.4V.
Analog Front End (AFE)
The analog front end is designed for 13.56 MHz according to
ISO 15693. The incoming data are demodulated from the
received ASK (Amplitude Shift Keying) signal which is 10 ~ 30%
or 100% modulated. Outgoing data are generated by the SL13A
load variation using Manchester coding with one or two
sub-carrier frequencies of 423.75 KHz (f c/32) or 484.28 KHz
(fc/28). The SL13A is compliant with the ISO 15693
recommendation for radio frequency power and signal
interface.
SL13A – 8
ams Datasheet: 2014-May-06 [v1-01]
Detailed Description
Processing and Digital Control
The SL13A is fully ISO 15693 compliant. Both data coding modes
(1 out of 256 and 1 out of 4) are supported by the SL13A. The
reader (interrogator) makes mode selection within the SOF
(Start of Frame).
The 1-of-256 data coding mode has a data rate of 1.65 kbit/s
(fc/8192) meaning that the transmission of one byte takes 4.833
ms. The 1-of-4 coding has a rate of 26.48 kbit/s (fc/512) with the
transmission of one byte taken 302.08 μs.

High
26.48 kbit/s (fc/512)
26.69 kbit/s (fc/508)
Serial Interface (SPI)
The integrated serial interface (SPI) can be used to read and
write the embedded EEPROM and to set the parameters. The
SPI interface is a secondary and test interface - the main
interface is the RF ISO15693 interface.
Real-Time Clock (RTC)
The on-chip real-time clock (RTC) is started through the
START- LOG command in which the start time is programmed in
UTC format. The interval for sensing and data logging can be
programmed in the range from 1 second up to 9 hours. The
accuracy of the timer is ±3%.
Temperature Sensor
The on-chip temperature sensor can measure the temperature
in the range from -20ºC to 60ºC within the specified accuracy.
The reference voltage for the A/D conversion is supplied from
an on chip calibrated Bandgap reference.
External Sensor
The external sensor pin (S EXT ) can be used to connect an
external sensor to the A/D converter. The voltage input range
is 300mV – 600mV and is fixed. For extra low power applications
the CE pin can switch the battery voltage for the time of the
external sensor A/D converter, so the current from the battery
into the sensor will flow only for this short time (max 5ms). This
can be enabled when the External-sensor flag is set to 1 and the
bit 19 in the Internal calibration data is set.
ams Datasheet: 2014-May-06 [v1-01]
SL13A – 9
Detailed Description
A/D Converter
An integrated 10-bit dual slope converter is used for the
temperature, battery and external sensor voltage conversions.
EEPROM Organization and Security
The EEPROM is organized into 3 areas - the System area, User
area and Measurement area. The System area has a fixed size
and can be accessed only by the proprietary commands. It is
protected by the Level 1 password - the System password. The
User and Measurement areas reside in the same address space
(256 blocks), but have separated passwords - the User password
and the Measurement password. The User and Measurement
are can be accessed by the standard ISO15693 read and write
commands. The User area size can be set by the Initialize
command. The minimum User area size is 1 block, the maximum
is 256 blocks. The size of the Measurement area is 256 blocks
minus User area. All blocks are 32 bits wide.
The password protection restricts only the write-type
commands. Read commands are always open. The password
protection can be activated for every area individually by
writing a value not equal to 0 to the password blocks.
The chip also supports a One-time use secure mode. When this
mode is used, all Measurement blocks are automatically locked
by the chip with the Start Log command. Those blocks cannot
be unlocked anymore even if the Level 3 (measurement)
password is known. This mode is intended for high security
applications where the 32-bit password does not provide
enough confidence.
Fully Passive Operation
The chip can be used in fully passive mode without a battery
supply. In this mode all functions are active only when the
antenna is in a RF field. For extended operation range in fully
passive mode, connect a 2.2μF capacitor between the VEXT and
V SS pins. The chip can be used also without this capacitor.

Functional Description
Figure 11, “State Transition Diagram,” on page 13 shows the
command overview.
Figure 14, “cool-Log™ Command Overview,” on page 14 shows
the different states and their interactions.
Initializing the Chip
A virgin chip (not initialized) can be initialized either through
the SPI bus or through the electromagnetic field from a reader
in the standby mode. The power source is either from a battery
(V BAT ) or extracted from the RF field via the AFE circuit. After
the initializing procedure, the chip will enter the ready mode.
If the External-Sensor flag is set, an external analog output
sensor can be connected to the S EXT pin.
Ready State
In the ready mode, all parameters can be set, read and changed
through a reader with the appropriate passwords.
Active State
In active mode, the real-time clock (RTC) is running, the desired
parameters are set and the on-chip temperature sensor is in
standby.
Logging State
A log flag from the timer will enable the logging mode in which
the sensor and the A/D converter will be activated, and the
measured value will be stored in the EEPROM together with the
time of the event. If the External Sensor flag is set, the external
sensor will also be activated and the measured data stored. The
A/D converter can be multiplexed between internal
temperature sensor, external sensor or battery voltage. After
the event, the chip will return to the active mode.
During the time of the logging procedure, the chip will not be
able to receive any RF command. If an RF command is sent
during this time, the chip will ignore it and will not send any
reply.

Passive State
In passive mode, the chip waits for the presence of an RF field
or for CE signal to go high. Current consumption from the

The GET-SYSTEM-INFO command gets the system
information of the chip, including info flags, UID, chip
revision, blocks and size.
• Set PW - #13
The SET-PW command sets the passwords for the selected
password level. The passwords are parallel, which means
that the user can protect individual areas and not affect
the other areas.
Security levels 1, 2 or 3, respectively.

• Set Log Mode - #14
The SET-LOG-MODE command defines the sensor type
(internal/external sensors), logging form, extreme upper
limit and storage rules.
Security level 1.
• Set Log Limits - #15
The SET-LOG-LIMITS command sets the logging higher,
lower and extreme lower limits. Those limits are used in
the Limits modes and ignored in the Dense mode.
Security level 1.
• Get Measurement Setup - #16
The GET-MEASUREMENT-SETUP command reads 4
system blocks - Start time, Log limits, Log mode and Delay
time.

Commands
• Set External Calibration Data - #17
The SET-EXT-CAL-DATA command sets the user
calibration values. Those values have no effect on the
internal calibration settings.
Security level 1.
• Set Internal Calibration Data - #18
The SET-INT-CAL-DATA command sets the calibration
values for the internal temperature sensor.
Security level 1.
• Set Passive - #19
The SET-PASSIVE command stops the logging procedure
and returns the chip to passive mode. It also stops the
timer.
Security level 1.
• Start Log - #20
The START-LOG command starts the logging procedure
and sets the Start time in UTC format. In logging state the
chips automatically performs the measurements and data
logging in the specified time intervals. Supported is also
a delayed start, which means that the chip will start with
the logging procedure with a specified delay after it
receives the START- LOG command.
Security level 1.
• Get Log State - #21
The GET-LOG-STATE command gets the log state of
following parameters: measurement status and out of
limits counter. This gives the ability to quickly check the
state of the package without the need to read the whole
temperature data log.
• Get Calibration Data - #22
The GET-CALIBRATION command reads the calibration
data for the internal and external sensors.
• Get Battery Level - #23
The GET-BAT-LEVEL command measures and reads the
voltage level of the battery.
• Verify PW - #24
The VERIFY-PW command is used to verify the various
passwords.
SL13A – 18
ams Datasheet: 2014-May-06 [v1-01]
Commands
• Initialize - #25
The INITIALIZE command sets the size of the user data
area and sets the delay time. If the Secure flag is set, the
chip automatically locks all measurement blocks. The
command clears the measurement status and limits
counter blocks.
Security level 1.
• Get temperature - #26
The GET-TEMPERATURE command measures and reads
the current chip temperature. The measured temperature
can be higher than the environment temperature, because
of the chip self-heating through the reader RF field. To ensure
correct measurement, the reader has to send this command
as soon as possible after the RF field is turned on.

Data Log Format
The SL13A device supports 3 different data log formats. The
data log format depends on the Logging form. The data log
formats are defined as follows:
Dense mode:
b31 - b30
b29
0
b20
b19
Temp. value 3
b10
b9
Temp. value 2
b0
Temp. value 1
Limits mode without battery check:
b31
b20
b19
Measurement #
b10
b9
0
b0
Temp. value
Limits mode with battery check:
b31
b20
b19
Measurement #
b10
b9
Battery value
b0
Temp. value
In Dense mode there is no Measurement number included,
because every measurement is stored to the EEPROM.
The Logging form is set with the Set Log Mode command and
is stored in the Bit30 and Bit29 in the Log mode field in the
EEPROM.

All values are stored to the measurement area. There are 3
10bit temperature values in each EEPROM block. The
upper 2 bits are 0. No Battery voltage storage is possible in
this mode.
All values that are out of the specified limits are stored to
the measurement area. There is only 1 measurement in
each EEPROM block. The temp. value is in the lower 10 bits
(b9 – b0). If Battery check is set to 1, the battery value is
stored to the next 10 bits. The upper 12 bits hold the
number of the measurement.

The upper 12 bits hold the number of the measurement.
ams Datasheet: 2014-May-06 [v1-01]
Commands
Out-of-Limits Counter
The Out-of-Limits counter can be used as an advanced alarm
mechanism. It is enabled in log format with temperature limits
and it will display the cumulative number of measurements that
are outside the specified limit. The application does not have
to read the whole EEPROM content in order to determine if the
temperature limits have been exceeded, just the Out-of-Limits
block. The Out-of-Limits counter block can be read out with the
Get Log State command.
Logging Timer
The SL13A device has an integrated RC oscillator that is
calibrated to 1024Hz. This oscillator drives the logging timer.
The logging timer resolution is 1 second, the maximum period
is 9.1 hours (32768 seconds).
The measurement real time is derived from 4 parameters - the
Start time (ST), the Delay time (DT), the measurement period
(MP) and the # of the measurement (NM). This value has to be
calculated in the reader by the equation:
Real time = ST+DT+MP*NM
Delay Time
The SL13A supports delayed start of the logging procedure. The
Delay time has a resolution of 8.53 minutes and a maximum
value of 582 hours (12 bits). The delay time value is set with the
Initialize command, while the Delay time counter starts
counting when the device receives the Start Log command.
Temperature Conversion
The calibration data does not have to be included in the
temperature conversion equation. The temperature value is
calculated as:
T(ºC) = code*0.169 – 92.7 – 5.4
LSB = 0.169ºC
offset = -92.7ºC
offset calibration = 0.169 * 32 = 5.4ºC
ams Datasheet: 2014-May-06 [v1-01]
SL13A – 31
Commands
Battery Voltage Conversion
The battery voltage conversion is dependent on the initial
battery voltage (1.5V or 3V).
For 1.5V battery, the equation is:
V = code*3.35mV + 860mV
LSB = 3.35mV
Offset = 860mV
For 3V battery:
V = code*6.32mV + 1.62V
LSB = 6.32mV
Offset = 1.62V
SPI Operation
Full and unlimited EEPROM access is possible through the SPI
interface. The primary function of the SPI interface is
production calibration and UID programming, but it can also
be used in application, where the ISO15693 interface cannot be
used.
Data on the D_IN pin is latched in on the falling edge of the
SCLK signal. Data on the D_OUT pin is shifted out on the falling
edge of the SCLK signal. The bytes are sent MSbit first.
The SPI communication is byte-oriented. It is composed of 3
fields of fixed length: Command field (1 byte), Address field (1
byte) and Data field (4 bytes).
The structure of the Command field is defined in the table
below.

Commands
The Address field holds the EEPROM address. Data field contains
the EEPROM data or Test vector.
The SPI communication is always organized into frames of 6
bytes, any other number of bytes will result in a communication
error. The communication has to end with a clock pulse - the
'execute' pulse. The whole number of clock pulses in a
communication frame is 49.
The only operation that requires more bytes is the EEPROM read
operation. After the 49th clock pulse, another 33 clock pulses
have to be generated, with a delay of at least 30μs after the
'execute' pulse. The data is shifted out with the last 32 clock
pulses.
The SPI supply will send an IRQ on the D_OUT pin after the
command is executed. In the SPI Write command, the D_OUT
signal will go high after the EEPROM write operation is fully
completed. This typically takes 12ms. In the SPI Read command,
the D_OUT signal will go high after the data is ready to be read.
In order to read the data, the master has to send 1 additional
clock pulse – the ACK pulse – before he starts to read the 32 bits
of data. In a Read command, the full operation takes 82 clock
pulses (48 for command + 1 Execute + 1 ACK + 32 data read).
The SPI interface is referenced to the V BAT supply. If the chip is
used in fully passive mode with external circuitry, the SPI
interface is referenced to the VEXT supply.

Temperature
The measurements have been performed on the following
equipment:
• Environmental chamber: ESPEC SU-241
• Reference temperature sensor: Testo 735 (system
accuracy of 0.05ºC)
• Reference temperature probe: Testo High accuracy Pt100
probe (0614 0235)
For each temperature point, 100 measurements were taken
using the logging function of the SL13A chip. The RF field of the
reader has been turned off during the temperature logging.

Applications
Applications
Typical Application
Figure 28 shows a typical application with a 1.5V battery, an
antenna coil and an optional external sensor module
(semi-passive mode).
Such application is typically used for automatic data logging
from on-chip temperature sensor or an external sensor
connected to S EXT.
The chip can store up to 762 measurement points. The intervals
between measurements as well as the limits are programmable.
It is possible to store all measuring points, or only the
measurements, which are outside predefined limits.

Applications
Passive Mode
Figure 29 shows a typical application without battery (passive
mode).
The SL13A chip also works in passive mode with no battery,
without the real-time clock function. This approach is intended
for applications in which a reader initiates the logging and
time-stamps the logging data.
The chip controls whether it takes data from internal or external
sensors. Access to the smart label chip is protected through a
3-level password authentication. Users can add other types of
external sensors to monitor shock control, humidity, or other
factors.

Applications
SPI Communication
Figure 30 shows an application using the SPI interface to
communicate with other circuitries.
The Serial Peripheral Interface (SPI) port can be connected to
external circuitries for display etc.; this allows further
communication between the chip and other circuits such as a
wireless transceiver for remote direct access to the logging data
and for easy setting of parameters and functions. The chip
supports an alarm system and functions that calculate shelf life.
Such applications are possible in both passive and semi-passive
mode. In passive mode, the chip provides a supply current of
maximum 4 mA from the V EXT assuming a reader provides
sufficient power from its field. The VEXT voltage is limited at 3.4V.
