PCF85116-3
2048 × 8-bit CMOS EEPROM with I2C-bus interface
Rev. 03 — 19 August 2002
Product data
1. Description
The PCF85116-3 is an 16 kbits (2048 × 8-bit) floating gate Electrically Erasable
Programmable Read Only Memory (EEPROM). By using redundant EEPROM cells it
is fault tolerant to single bit errors. In most cases multi bit errors are also covered.
This feature dramatically increases reliability compared to conventional EEPROM
memories. Power consumption is low due to the full CMOS technology used. The
programming voltage is generated on-chip, using a voltage multiplier.
As data bytes are received and transmitted via the serial I2C-bus, a package using
eight pins is sufficient. Only one PCF85116-3 device is required to support all eight
blocks of 256 × 8-bit each.
Timing of the E/W cycle is carried out internally, thus no external components are
required. A write-protection input at pin 7 (WP) allows disabling of write-commands
from the master by a hardware signal. When pin 7 is HIGH, data in the EEPROM are
protected. The data bytes received will not be acknowledged by the PCF85116-3 and
the EEPROM contents are not changed.
Remark: The PCF85116-3 is pin and address compatible to the PCx85xxC-2 family.
The PCF85116-3 covers the whole address space of 16 kbits; address inputs are no
longer needed. Therefore, pins 1 to 3 are not connected. The write-protection input
(WP) is on pin 7.

8. Functional description
8.1 I2C-bus protocol
The I2C-bus is for 2-way, 2-line communication between different ICs or modules. The
serial bus consists of two bidirectional lines; one for data signals (SDA), and one for
clock signals (SCL).
Both the SDA and SCL lines must be connected to a positive supply voltage via a
pull-up resistor.
The following protocol has been defined:
• Data transfer may be initiated only when the bus is not busy.
• During data transfer, the data line must remain stable whenever the clock line is
HIGH. Changes in the data line while the clock line is HIGH will be interpreted as
control signals.
8.1.1 Bus conditions
The following bus conditions have been defined:
Bus not busy — Both data and clock lines remain HIGH.
Start data transfer — A change in the state of the data line, from HIGH-to-LOW,
while the clock is HIGH, defines the START condition.
Stop data transfer — A change in the state of the data line, from LOW-to-HIGH,
while the clock is HIGH, defines the STOP condition.
Data valid — The state of the data line represents valid data when, after a START
condition, the data line is stable for the duration of the HIGH period of the clock
signal. There is one clock pulse per bit of data.
8.1.2 Data transfer
Each data transfer is initiated with a START condition and terminated with a STOP
condition. The number of the data bytes transferred between the START and STOP
conditions is limited to 32 bytes in the E/W mode.
Data transfer is unlimited in the read mode. The information is transmitted in bytes
and each receiver acknowledges with a ninth bit.
Within the I2C-bus specifications a low-speed mode (2 kHz clock rate), a high-speed
mode (100 kHz clock rate) and a fast speed mode (400 kHz clock rate) are defined.
The PCF85116-3 operates in all three modes.
By definition, a device that sends a signal is called a ‘transmitter’, and the device
which receives the signal is called a ‘receiver’. The device which controls the signal is
called the ‘master’. The devices that are controlled by the master are called ‘slaves’.
Each byte is followed by one acknowledge bit. This acknowledge bit is a HIGH level,
put on the bus by the transmitter. The master generates an extra acknowledge related
clock pulse. The slave receiver which is addressed is obliged to generate an
acknowledge after the reception of each byte.

Philips Semiconductors
2048 × 8-bit CMOS EEPROM with I2C-bus interface
The 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 has to pull down the SDA line during the acknowledge
clock pulse in such a way 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. A master receiver must signal an
end of data to the slave 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 generation of the STOP condition.
8.1.3 Device addressing
Following a START condition, the bus master must output the address of the slave it
is accessing. The four MSBs of the slave address are the device type identifier (see
Figure 3). For the PCF85116-3 this is fixed to ‘1010’.
Fig 3. Slave address.
The next three significant bits of the slave address field (B3, B2, B1) are the block
selection bits. It is used by the host to select one out of eight blocks
(1 block = 256 bytes of memory). These are, in effect, the three most significant bits
of the word address.
The last bit of the slave address (R/W) defines the operation to be performed. When
R/W is set to logic 1, a read operation is selected.
8.1.4 Write operations
Byte/word write: For a write operation, the PCF85116-3 requires a second address
field. This address field is a word address providing access to any one of the eight
blocks of memory. Upon receipt of the word address, the PCF85116-3 responds with
an acknowledge and awaits the next eight bits of data, again responding with an
acknowledge. Word address is automatically incremented. The master can now
terminate the transfer by generating a STOP condition.
After this STOP condition, the E/W cycle starts and the bus is free for another
transmission. Its duration is a maximum of 10 ms.
During the E/W cycle the slave receiver does not send an acknowledge bit if
addressed via the I2C-bus.
Page write: The PCF85116-3 is capable of a 32-byte page write operation. It is
initiated in the same manner as the byte write operation. The master can transmit up
to 32 data bytes within one transmission. After receipt of each byte, the PCF85116-3
will respond with an acknowledge. The master terminates the transfer by generating a
STOP condition. The maximum total E/W time in this mode is 10 ms.

Philips Semiconductors
2048 × 8-bit CMOS EEPROM with I2C-bus interface
After the receipt of each data byte, the six high-order bits of the memory address
providing access to one of the 64 pages of the memory remain unchanged. The five
low-order bits of the memory address will be incremented only (see Figure 4). By
these five bits a single byte within the page in access is selected. By an increment the
memory address may change from 31 to 0, from 63 to 32, etc. If the master transmits
more than 32 bytes prior to generating the STOP condition, data within the addressed
page may be overwritten and unpredictable results may occur. As in the byte write
operation, all inputs are disabled until completion of the internal write cycles.

Remark: Write accesses to the EEPROM are enabled if the pin WP is LOW. When
WP is HIGH the EEPROM is write-protected and no acknowledge will be given by the
PCF85116-3 when data is sent. However, an acknowledge will be given after the
slave address and the word address.

8.1.5 Read operations
Read operations are initiated in the same manner as write operations with the
exception that the LSB of the slave address (R/W) is set to logic 1.
There are three basic read operations: current address read, random read, and
sequential read.
Remark: During read operations all bits of the memory address are incremented
after each transmission of a data byte. Contrary to write operations, an overflow of the
memory address occurs from 2047 to 0 (see Figure 8).

14. Soldering
14.1 Introduction
This text gives a very brief insight to a complex technology. A more in-depth account
of soldering ICs can be found in our Data Handbook IC26; Integrated Circuit
Packages (document order number 9398 652 90011).
There is no soldering method that is ideal for all IC packages. Wave soldering is often
preferred when through-hole and surface mount components are mixed on one
printed-circuit board. Wave soldering can still be used for certain surface mount ICs,
but it is not suitable for fine pitch SMDs. In these situations reflow soldering is
recommended.
14.2 Surface mount packages
14.2.1 Reflow soldering
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 methods exist for reflowing; for example, convection or convection/infrared
heating in a conveyor type oven. Throughput times (preheating, soldering and
cooling) vary between 100 and 200 seconds depending on heating method.
Typical reflow peak temperatures range from 215 to 250 °C. The top-surface
temperature of the packages should preferable be kept below 220 °C for thick/large
packages, and below 235 °C for small/thin packages.
14.2.2 Wave soldering
Conventional single wave soldering is not recommended for surface mount devices
(SMDs) or printed-circuit boards with a high component density, as solder bridging
and non-wetting can present major problems.
To overcome these problems the double-wave soldering method was specifically
developed.
If wave soldering is used the following conditions must be observed for optimal
results:
• Use a double-wave soldering method comprising a turbulent wave with high
upward pressure followed by a smooth laminar wave.
• For packages with leads on two sides and a pitch (e):
– larger than or equal to 1.27 mm, the footprint longitudinal axis is preferred to be
parallel to the transport direction of the printed-circuit board;
– smaller than 1.27 mm, the footprint longitudinal axis must be parallel to the
transport direction of the printed-circuit board.
The footprint must incorporate solder thieves at the downstream end.

• For packages with leads on four sides, the footprint must be placed at a 45° angle
to the transport direction of the printed-circuit board. The footprint must
incorporate solder thieves downstream and at the side corners.
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.
Typical dwell time is 4 seconds at 250 °C. A mildly-activated flux will eliminate the
need for removal of corrosive residues in most applications.
14.2.3 Manual soldering
Fix the component by first soldering two diagonally-opposite end leads. Use a low
voltage (24 V or less) soldering iron 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.
14.3 Through-hole mount packages
14.3.1 Soldering by dipping or by solder wave
The maximum permissible temperature of the solder is 260 °C; solder at this
temperature must not be in contact with the joints for more than 5 seconds. The total
contact time of successive solder waves must not exceed 5 seconds.
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.
14.3.2 Manual soldering
Apply the soldering iron (24 V or less) to the lead(s) of the package, either 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.

[1] For more detailed information on the BGA packages refer to the (LF)BGA Application Note
(AN01026); order a copy from your Philips Semiconductors sales office.
[2] All surface mount (SMD) packages are moisture sensitive. Depending upon the moisture content, the
maximum temperature (with respect to time) and body size of the package, there is a risk that internal
or external package cracks may occur due to vaporization of the moisture in them (the so called
popcorn effect). For details, refer to the Drypack information in the Data Handbook IC26; Integrated
Circuit Packages; Section: Packing Methods.
[3] For SDIP packages, the longitudinal axis must be parallel to the transport direction of the
printed-circuit board.
[4] These packages are not suitable for wave soldering. On versions with the heatsink on the bottom
side, the solder cannot penetrate between the printed-circuit board and the heatsink. On versions with
the heatsink on the top side, the solder might be deposited on the heatsink surface.
[5] If wave soldering is considered, then the package must be placed at a 45° angle to the solder wave
direction. The package footprint must incorporate solder thieves downstream and at the side corners.
[6] Wave soldering is suitable for LQFP, QFP and TQFP packages with a pitch (e) larger than 0.8 mm; it
is definitely not suitable for packages with a pitch (e) equal to or smaller than 0.65 mm.
[7] Wave soldering is suitable for SSOP and TSSOP packages with a pitch (e) equal to or larger than
0.65 mm; it is definitely not suitable for packages with a pitch (e) equal to or smaller than 0.5 mm.
