The shared properties of the PCF84CxxxA family of microcontrollers are described in the "PCD84xxxA family" data sheet which should be read in conjunction with this publication. The PCF84C85A is a general purpose CMOS microcontroller with emphasis on input/output. It provides 32 I/O port lines, 8 kbytes of program memory and 256 bytes of RAM. In addition to the 32 I/O port lines, the microcontroller provides an on-chip I2C-bus interface. This two-line serial bus extends the microcontroller's capabilities when implemented with the powerful I2C-bus peripherals.These include LCD drivers, telecom circuits, AD/DA converters, clock/calendar circuits, EEPROM and RAM and are listed in "Data Handbook IC12, I2C Peripherals". The instruction set is based on that of the MAB8048 and is a sub-set of that listed in the "PCF84CXXXA family" data sheet.

Dwell times vary between 50 and 300 seconds depending on heating method. Typical reflow temperatures range from 215 to 250 C. Preheating is necessary to dry the paste and evaporate the binding agent. Preheating duration: 45 minutes at 45 C. 15.3.2 WAVE SOLDERING 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. 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). 15.2 15.2.1 DIP SOLDERING BY DIPPING OR BY WAVE Wave soldering techniques can be used for all SO and VSO packages if the following conditions are observed: * A double-wave (a turbulent wave with high upward pressure 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. * The package footprint must incorporate solder thieves at the downstream end. 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. 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. A mildly-activated flux will eliminate the need for removal of corrosive residues in most applications. 15.3.3 REPAIRING SOLDERED JOINTS 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. 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. 15.2.2 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. 15.3 15.3.1 SO and VSO REFLOW SOLDERING Reflow soldering techniques are suitable for all SO and VSO packages. 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. Fix the component by first soldering two diagonallyopposite 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. 1996 Nov 21 16 Philips Semiconductors Product specification Microcontroller with extended I/O 16 DEFINITIONS Data sheet status Objective specification Preliminary specification Product specification Limiting values PCF84C85A This data sheet contains target or goal specifications for product development.
