Power-on reset For correct operation of the Power-on reset the rise time of VDD from 0 V to 1.55 V should be less than 0.1 ms. All resettable flip-flops are reset. Additionally the polarity of the first motor pulse is positive: VM1 - VM2 0 V. PCA167x series Customer testing and stop mode An output frequency of 32 Hz is provided at RESET (pin 8) to be used for exact frequency measurement. Connecting the RESET to VDD stops the motor pulses leaving them in a HIGH impedance 3-state condition and a 32 Hz signal is produced at the TEST pin. A debounce circuit protects against accidental stoppages due to mechanical shock to the watch (tDEB = 14.7 to 123.2 ms). Connecting RESET to VSS activates the test mode. The motor pulse period is 31.25 ms instead of tT. Test and stop mode are disabled by disconnecting RESET (open-circuit). AVAILABLE TYPES Refer to Fig.2 and to Chapters "Ordering information" and "Functional description and testing". SPECIFICATIONS SHORT TYPE NUMBER 1672 1673 1675 1676 1677 Note 1.

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). Reflow soldering Reflow soldering techniques are suitable for all SO 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. Several techniques exist for reflowing; for example, thermal conduction by heated belt. 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. Wave soldering PCA167x series Wave soldering techniques can be used for all SO 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. Repairing soldered joints 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. 1998 Apr 03 9 Philips Semiconductors Product specification 32 kHz watch circuits using a silver-oxide or a 3 V lithium battery DEFINITIONS Data sheet status Objective specification Preliminary specification Product specification Limiting values PCA167x series This data sheet contains target or goal specifications for product development.
