 PCF8582C-2
256 x 8-bit CMOS EEPROM with I2C-bus interface
Rev. 02 -- 09 May 2002 Product data
1. Description
The PCF8582C-2 is a floating gate Electrically Erasable Programmable Read Only Memory (EEPROM) with 2 kbits (256 x 8-bit) non-volatile storage. By using an internal redundant storage code, it is fault tolerant to single bit errors. This feature dramatically increases the reliability compared to conventional EEPROMs. Power consumption is low due to the full CMOS technology used. The programming voltage is generated on-chip, using a voltage multiplier. Data bytes are received and transmitted via the serial I2C-bus. Up to eight PCF8582C-2 devices may be connected to the I2C-bus. Chip select is accomplished by three address inputs (A0, A1 and A2). Timing of the E/W cycle is carried out internally, thus no external components are required. Programming Time Control (PTC), Pin 7, must be connected to either VDD or left open-circuit. There is an option of using an external clock for timing the length of an E/W cycle.

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 7 bytes in the E/W mode and 8 bytes in the Page 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 high-speed mode (100 kHz clock rate) and a fast speed mode (400 kHz clock rate) are defined. The PCF8582C-2 operates in only the high-speed mode. 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.

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 address of the PCF8582C-2 is shown in Figure 4. To conserve power, no internal pullup resistors are incorporated on the hardware selectable pins and they must be connected to either VDD or VSS.

Fig 4. Slave address.
The last bit of the slave address defines the operation to be performed. When set to logic 1, a read operation is selected, while a logic 0 selects a write operation. 8.1.4 Write operations Byte/word write: For a write operation, the PCF8582C-2 requires a second address field. This address field is a word address providing access to the 256 words of memory. Upon receipt of the word address, the PCF8582C-2 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 or transmit up to six more bytes of data and then terminate 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 10 ms per byte. During the E/W cycle the slave receiver does not send an acknowledge bit if addressed via the I2C-bus.

Page write: The PCF8582C-2 is capable of an eight-byte page write operation. It is initiated in the same manner as the byte write operation. The master can transit eight data bytes within one transmission. After receipt of each byte, the PCF8582C-2 will respond with an acknowledge. The typical E/W time in this mode is 9 x 3.5 ms = 31.5 ms. Erasing a block of 8 bytes in page mode takes typical 3.5 ms and sequential writing of these 8 bytes another typical 28 ms. After the receipt of each data byte, the three low-order bits of the word address are internally incremented. The high-order five 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 8th 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 and 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.

Read operations Read operations are initiated in the same manner 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. Remark: The lower 8 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, and from 511 to 256.

15. Soldering
15.1 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.
15.2 Surface mount packages
15.2.1 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. 15.2.2 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. 15.2.3 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.
15.3 Through-hole mount packages
15.3.1 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. 15.3.2 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.

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. 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. For SDIP packages, the longitudinal axis must be parallel to the transport direction of the printed-circuit board. 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. 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. 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. 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.
