Power consumption is low due to the full CMOS technology used. The programming voltage is generated on-chip, using a voltage multiplier. The PCF8510x-2 is pin compatible to widely used industrial pinning (pin 7 not connected). • On-chip voltage multiplier • Serial input/output I2C-bus • Write operations: – byte write mode – 8-byte page write mode (minimizes total write time per byte). As data bytes are received and transmitted via the serial I2C-bus, a package using eight pins is sufficient. Up to sixteen PCF8510xC-2 devices may be connected to the I2C-bus. This is possible with the introduction of a second device selection code. Chip select is accomplished by three address inputs (A0, A1 and A2) for each PCF8510xC-2 type. • Read operations: – sequential read – random read. • Internal timer for writing (no external components) • Power-on reset • High reliability by using a redundant storage code • Endurance: 1000000 Erase/Write (E/W) cycles at Tamb = 22 °C • 10 years non-volatile data retention time • Standard industrial pinning (pin 7 not connected) • Up to sixteen EEPROMs addressable in one I2C-bus using both PCF85102 and PCF85103 in combination. 3 QUICK REFERENCE DATA SYMBOL PARAMETER VDD supply voltage IDDR supply current read IDDW IDDstb 2000 Feb 15 supply current E/W standby supply current CONDITIONS MIN.

The information is transmitted in bytes and each receiver acknowledges with a ninth bit. I2C-BUS PROTOCOL The I2C-bus is designed 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). Within the I2C-bus specifications, a low-speed mode (2 kHz clock rate) and a high speed mode (100 kHz clock rate) are defined. The PCF8510xC-2 operates in both modes. Both the SDA and SCL lines must be connected to a positive supply voltage via a pull-up resistor. By definition, a device that sends a signal is called a ‘transmitter’, and the device that receives the signal is called a ‘receiver’. The device that controls the signal is called the ‘master’. The devices that are controlled by the master are called ‘slaves’. 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 Each byte is followed by one acknowledge bit, which is placed on the bus at a HIGH level by the transmitter. The master generates an extra acknowledge-related clock pulse. The slave receiver that is addressed is obliged to generate an acknowledge after the reception of each byte. Bus conditions The following bus conditions have been defined: The master receiver must generate an acknowledge after the reception of each byte that has been clocked out of the slave transmitter. • 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. The device that acknowledges has to pull the SDA line down 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. • 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. 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. • 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. 8.2 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 seven bytes in the E/W mode and eight bytes in the page E/W mode. 2000 Feb 15 7 Philips Semiconductors Product specification 256 × 8-bit CMOS EEPROMs with I2C-bus interface 8.3 PCF85102C-2; PCF85103C-2 Device addressing 8.4 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 Fig.4 and Fig.5). For the PCF85102C-2, this is fixed to ‘1010’, for the PCF85103C-2 to ‘0010’. 8.4.1 After this STOP condition, the E/W cycle starts and the bus is free for another transmission. The duration of the E/W cycle is 10 ms per byte. The last bit of the slave address defines the operation to be performed. When set to logic 1, a read operation is selected. During the E/W cycle, the slave receiver does not send an acknowledge bit if addressed via the I2C-bus. Address bits must be connected to either VDD or VSS. 8.4.2 1 0 1 0 A2 A1 Fig.4 Slave address for PCF85102C-2. 0 0 1 0 A2 A1 After the receipt of each data byte, the three low order bits of the word address are internally incremented. The five high order bits of the address remain unchanged. The slave acknowledges the reception of each data byte with an ACK. The I2C-bus data transfer is terminated by the master after the eighth byte with a STOP condition. If the master transmits more than eight bytes prior to generating the STOP condition, no acknowledge will be given on the ninth (and following) data bytes. Also, the whole transmission will be ignored and no programming will be done. As in the byte write operation, all inputs are disabled until completion of the internal write cycles. A0 R/W MGL970 Fig.5 Slave address for PCF85103C-2. 8.3.1 REMARK The I2C-bus device select address ‘0010’ is not exclusively reserved for device PCF85103C-2. Therefore, multiple use has to be checked in advance. 2000 Feb 15 PAGE WRITE The PCF8510xC-2 is capable of an 8-byte page write operation. It is initiated in the same manner as the byte write operation. The master can transmit eight data bytes within one transmission. After receipt of each byte, the PCF8510xC-2 will respond with an acknowledge. The typical E/W time in this mode is 9 × 3.5 ms = 31.5 ms. Erasing a block of eight bytes in page mode takes a typical 3.5 ms and sequential writing of these eight bytes another typical 28 ms. A0 R/W MBC793 handbook, halfpage BYTE/WORD WRITE For a write operation, the PCF8510xC-2 requires a second address field. This address field is a word address providing access to the 256 words of memory. On receipt of the word address, the PCF8510xC-2 responds with an acknowledge and awaits the next eight bits of data, again responding with an acknowledge. The word address is automatically incremented. The master can now terminate the transfer by generating a STOP condition or transmitting up to six more bytes of data and then terminating by generating a STOP condition. The next three significant bits address a particular device or memory page (page = 256 bytes of memory). A system could have up to sixteen PCF8510xC-2 devices on the bus. This can be achieved with eight PCF85102C devices and eight PCF85103C devices, combined on one I2C-bus. The eight addresses are defined by the state of the A0, A1 and A2 inputs per type. handbook, halfpage Write operations 8 Philips Semiconductors Product specification 256 × 8-bit CMOS EEPROMs with I2C-bus interface S acknowledge from slave acknowledge from slave handbook, full pagewidth 0 A SLAVE ADDRESS PCF85102C-2; PCF85103C-2 WORD ADDRESS A acknowledge from slave DATA acknowledge from slave DATA A A P R/W auto increment word address auto increment word address MBA701 Fig.6 Auto increment memory word address; two byte write. handbook, full pagewidth S acknowledge from slave SLAVE ADDRESS 0 A acknowledge from slave WORD ADDRESS acknowledge from slave DATA N A A acknowledge from slave DATA N + 1 A R/W auto increment word address auto increment word address acknowledge from slave DATA N + 7 1 A last byte MBA702 Fig.7 Page write operation; eight bytes. 2000 Feb 15 9 auto increment word address Philips Semiconductors Product specification 256 × 8-bit CMOS EEPROMs with I2C-bus interface 8.5 PCF85102C-2; PCF85103C-2 Read operations 8.5.1 The lower eight bits of the word address are incremented after each transmission of a data byte (read or write). The MSB of the word address, which is defined in the slave address, is not changed when the word address count overflows. Thus, the word address overflows from 255 to 0. The read operations are initiated in the same way as write operations, with the exception that the LSB of the slave address is set to logic 1. There are three basic read operations; current address read, random read and sequential read sequential read.

The top-surface temperature of the packages should preferable be kept below 230 °C. 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). 14.3.2 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. 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. However, wave soldering is not always suitable for surface mount ICs, or for printed-circuit boards with high population densities. In these situations reflow soldering is often used. 14.2 14.2.1 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. Through-hole mount packages SOLDERING BY DIPPING OR BY SOLDER WAVE • For packages with leads on two sides and a pitch (e): 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. – 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 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. 14.2.2 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. 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. 14.3 14.3.1 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. 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. Surface mount packages REFLOW SOLDERING 14.3.3 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. 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. Several methods exist for reflowing; for example, infrared/convection heating in a conveyor type oven. Throughput times (preheating, soldering and cooling) vary between 100 and 200 seconds depending on heating method. 2000 Feb 15 WAVE SOLDERING When using a dedicated tool, all other leads can be soldered in one operation within 2 to 5 seconds between 270 and 320 °C. 16 Philips Semiconductors Product specification 256 × 8-bit CMOS EEPROMs with I2C-bus interface 14.4 PCF85102C-2; PCF85103C-2 Suitability of IC packages for wave, reflow and dipping soldering methods SOLDERING METHOD MOUNTING PACKAGE WAVE suitable(2) Through-hole mount DBS, DIP, HDIP, SDIP, SIL Surface mount REFLOW(1) DIPPING − suitable BGA, LFBGA, SQFP, TFBGA not suitable suitable − HBCC, HLQFP, HSQFP, HSOP, HTQFP, HTSSOP, SMS not suitable(3) suitable − PLCC(4), SO, SOJ suitable suitable − suitable − suitable − recommended(4)(5) LQFP, QFP, TQFP not SSOP, TSSOP, VSO not recommended(6) Notes 1. 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”. 2. For SDIP packages, the longitudinal axis must be parallel to the transport direction of the printed-circuit board. 3. These packages are not suitable for wave soldering as a solder joint between the printed-circuit board and heatsink (at bottom version) can not be achieved, and as solder may stick to the heatsink (on top version). 4. If wave soldering is considered, then the package must be placed at a 45° angle to the solder wave direction.
