CHARACTERISTICS OF THE I2C-BUS
The I2C-bus is for 2-way, 2-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 when connected to the output stages of a device.
Data transfer may be initiated only when the bus is not busy.
Start and stop conditions
Both data and clock lines remain HIGH when the 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)
(see Figure 4).
Bit transfer
One data bit is transferred during each clock phase. 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
control signals (See Figure 3).
System configuration
A device generating a message is a “transmitter”, a device receiving
is the “receiver”. The device that controls the message is the
“master” and the devices which are controlled by the master are the
“slaves” (see Figure 5).

out of the slave transmitter. The device that acknowledges has to
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, set–up and hold times must be
taken into account.
Acknowledge (see Figure 6)
The number of data bytes transferred between the start and the stop
conditions from transmitter to receiver is not limited. Each byte of
eight bits is followed by one acknowledge bit. The acknowledge bit
is a HIGH level put on the bus by the transmitter whereas the
master generates an extra acknowledge related clock pulse.
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.
A slave receiver which is addressed must generate an acknowledge
after the reception of each byte. Also a master must generate an
acknowledge after the reception of each byte that has been clocked

Asynchronous Start
Following any Start condition on the bus, a minimum of 9 SCL clock cycles must be completed before a Stop condition can be issued. The
device does not support a Stop or a repeated Start condition during this time period.
I/O OPERATIONS (see also Figure 7)
Each of the PTN3500’s eight I/Os can be independently used as an input or output. Input I/O data is transferred from the port to the
microcontroller by the READ mode (See Figure 10). Output data is transmitted to the port by the I/O WRITE mode (see Figure 9).

Quasi-bidirectional I/Os (see Figure 11)
A quasi-bidirectional I/O can be used as an input or output without the use of a control signal for data direction. At power-on the I/Os are HIGH.
In this mode, only a current source to VDD is active. An additional strong pull-up to VDD allows fast rising edges into heavily loaded outputs.
These devices turn on when an output is written HIGH, and are switched off by the negative edge of SCL. The I/Os should be HIGH before
being used as inputs.

the master issues the stop condition, initiating the internal write cycle
to the non-volatile memory. Only write and read operations to the
Quasi-bidirectional I/O are allowed during the internal write cycle.
MEMORY OPERATIONS
Write operations
Write operations require an additional address field to indicate the
memory address location to be written. The address field is eight
bits long, providing access to any one of the 256 words of memory.
There are two types of write operations, byte write and page write.
Page Write (see Figure 13)
A page write is initiated in the same way as the byte write. If after
sending the first word of data, the stop condition is not received the
PTN3500 considers subsequent words as data. After each data
word the PTN3500 responds with an acknowledge and the two least
significant bits of the memory address field are incremented. Should
the master not send a stop condition after four data words the
address counter will return to its initial value and overwrite the data
previously written. After the receipt of the stop condition the inputs
will behave as with the byte write during the internal write cycle.
Byte Write (see Figure 12)
To perform a byte write the start condition is followed by the memory
slave address and the R/W bit set to 0. The PTN3500 will respond
with an acknowledge and then consider the next eight bits sent as
the word address and the eight bits after the word address as the
data. The PTN3500 will issue an acknowledge after the receipt of
both the word address and the data. To terminate the data transfer

The master must perform a byte write to the address location to be
read, but instead of transmitting the data after receiving the
acknowledge from the PTN3500 the master reissues the start
condition and memory slave address with the R/W bit set to one.
The PTN3500 will then transmit an acknowledge and use the next
eight clock cycles to transmit the data contained in the addressed
location. The master ceases the transmission by issuing the stop
condition after the eighth bit, omitting the ninth clock cycle
acknowledge.
Read operations
PTN3500 read operations are initiated in an identical manner to
write operations with the exception that the memory slave address’
R/W bit is set to a one. There are three types of read operations;
current address, random and sequential.
Current Address Read (see Figure 14)
The PTN3500 contains an internal address counter that increments
after each read or write access, as a result if the last word accessed
was at address n then the address counter contains the address
n+1.
Sequential Read (see Figure 16)
The PTN3500 sequential read is an extension of either the current
address read or random read. If the master doesn’t issue a stop
condition after it has received the eighth data bit, but instead issues
an acknowledge, the PTN3500 will increment the address counter
and use the next eight cycles to transmit the data from that location.
The master can continue this process to read the contents of the
entire memory. Upon reaching address 255 the counter will return to
address 0 and continue transmitting data until a stop condition is
received. The master ceases the transmission by issuing the stop
condition after the eighth bit, omitting the ninth clock cycle
acknowledge.
When the PTN3500 receives its memory slave address with the
R/W bit set to one it issues an acknowledge and uses the next eight
clocks to transmit the data contained at the address stored in the
address counter. The master ceases the transmission by issuing the
stop condition after the eighth bit. There is no ninth clock cycle for
the acknowledge.
Random Read (see Figure 15)
The PTN3500’s random read mode allows the address to be read
from to be specified by the master. This is done by performing a
dummy write to set the address counter to the location to be read.

SOLDERING
seconds depending on heating method. Typical reflow temperatures
range from 215 to 250°C.
Introduction
There is no soldering method that is ideal for all IC packages. Wave
soldering is often preferred when through-hole and surface mounted
components are mixed on one printed-circuit board. However, wave
soldering is not always suitable for surface mounted ICs, or for
printed-circuits with high population densities. In these situations
reflow soldering is often used.
Preheating is necessary to dry the paste and evaporate the binding
agent. Preheating duration: 45 minutes at 45°C.
Wave soldering
Wave soldering is not recommended for SSOP packages. This is
because of the likelihood of solder bridging due to closely-spaced
leads and the possibility of incomplete solder penetration in
multi-lead devices.
This text gives a very brief insight to a complex technology. A more
in-depth account of soldering ICs can be found in our IC Package
Databook (order code 9398 652 90011).
If wave soldering cannot be avoided, the following conditions
must be observed:
DIP
• A double-wave (a turbulent wave with high upward pressure
Soldering by dipping or by wave
The maximum permissible temperature of the solder is 260°C;
solder at this temperature must not be in contact with the joint for
more than 5 seconds. The total contact time of successive solder
waves must not exceed 5 seconds.
followed by a smooth laminar wave) soldering technique
should be used.
• The longitudinal axis of the package footprint must be
parallel to the solder flow and must incorporate solder
thieves at the downstream end.
The device may be mounted up to the seating plane, but the
temperature of the plastic body must not exceed the specified
maximum storage temperature (Tstg max). If the printed-circuit board
has been pre-heated, forced cooling may be necessary immediately
after soldering to keep the temperature within the permissible limit.
Even with these conditions, only consider wave soldering
SSOP packages that have a body width of 4.4 mm, that is
SSOP16 (SOT369–1) or SSOP20 (SOT266–1).
During placement and before soldering, the package must be fixed
with a droplet of adhesive. The adhesive can be applied by screen
printing, pin transfer or syringe dispensing. The package can be
soldered after the adhesive is cured.
Repairing soldered joints
Apply a low voltage soldering iron (less than 24 V) to the lead(s) of
the package, below the seating plane or not more than 2 mm above
it. If the temperature of the soldering iron bit is less than 300°C it
may remain in contact for up to 10 seconds. If the bit temperature is
between 300 and 400°C, contact may be up to 5 seconds.
Maximum permissible solder temperature is 260°C, and maximum
duration of package immersion in solder is 10 seconds, if cooled to
less than 150°C within 6 seconds. Typical dwell time is 4 seconds at
250°C.
SO and SSOP
A mildly-activated flux will eliminate the need for removal of
corrosive residues in most applications.
Reflow soldering
Reflow soldering techniques are suitable for all SO and SSOP
packages.
Repairing soldered joints
Fix the component by first soldering two diagonally opposite end
leads. Use only a low voltage soldering iron (less than 24 V) applied
to the flat part of the lead. Contact time must be limited to
10 seconds at up to 300 °C. When using a dedicated tool, all other
leads can be soldered in one operation within 2 to 5 seconds
between 270 and 320°C.
Reflow soldering requires solder paste (a suspension of fine solder
particles, flux and binding agent) to be applied to the printed-circuit
board by screen printing, stencilling or pressure-syringe dispensing
before package placement.
Several techniques exist for reflowing; for example, thermal
conduction by heated belt. Dwell times vary between 50 and 300
