Only PCF2116 registers, Instruction Register (IR) Data Register (DR) directly controlled MPU. Before internal operation, control information stored temporarily these registers allow interface various types MPUs which operate different speeds allow interface peripheral control ICs. PCF2116 operation controlled instructions shown Table together with their execution time. Details explained subsequent sections. Instructions categories, those that: Designate PCF2116 functions such display format, data length, etc. internal addresses Perform data transfer with internal Others. normal use, category instructions used most frequently. However, automatic incrementing decrementing internal addresses after each data write lessens program load. display shift particular performed concurrently with display data write, enabling designer develop systems minimum time with maximum programming efficiency. During internal operation, instruction other than busy flag/address read instruction will executed. Because busy flag logic while instruction being executed, check make sure logic before sending next instruction wait maximum instruction execution time, given Table instruction sent while busy flag HIGH will executed.

8-bit operation, 1-line display using internal reset Table shows example 1-line display 8-bit operation. PCF2116 functions must function instruction prior display. Since display data store data characters, used advertising displays when combined with display shift operation. Since display shift operation changes display position only DDRAM contents remain unchanged, display data entered first displayed when Return Home operation performed. 4-bit operation, 1-line display using internal reset program must functions prior 4-bit operation. Table shows example. When power turned 8-bit operation automatically selected PCF2116 attempts perform first write 8-bit operation. Since nothing connected DB3, rewrite then required.

SOLDERING Introduction There soldering method that ideal packages. Wave soldering often preferred when through-hole surface mounted components mixed printed-circuit board. However, wave soldering always suitable surface mounted ICs, printed-circuits with high population densities. these situations reflow soldering often used. This text gives very brief insight complex technology. more in-depth account soldering found Package Databook" (order code 9398 90011). Reflow soldering Reflow soldering techniques suitable LQFP packages. Reflow soldering requires solder paste suspension fine solder particles, flux binding agent) applied printed-circuit board screen printing, stencilling pressure-syringe dispensing before package placement. Several techniques exist reflowing; example, thermal conduction heated belt. Dwell times vary between seconds depending heating method. Typical reflow temperatures range from Preheating necessary paste evaporate binding agent. Preheating duration: minutes Wave soldering Wave soldering recommended LQFP packages. This because likelihood solder bridging closely-spaced leads possibility incomplete solder penetration multi-lead devices.

wave soldering cannot avoided, following conditions must observed: double-wave turbulent wave with high upward pressure followed smooth laminar wave) soldering technique should used. footprint must angle board direction must incorporate solder thieves downstream side corners. Even with these conditions, consider wave soldering LQFP packages LQFP48 (SOT313-2), LQFP64 (SOT314-2) LQFP80 (SOT315-1). During placement before soldering, package must fixed with droplet adhesive. adhesive applied screen printing, transfer syringe dispensing. package soldered after adhesive cured. Maximum permissible solder temperature maximum duration package immersion solder seconds, cooled less than within seconds. Typical dwell time seconds mildly-activated flux will eliminate need removal corrosive residues most applications. Repairing soldered joints component first soldering diagonallyopposite leads. only voltage soldering iron (less than applied flat part lead. Contact time must limited seconds When using dedicated tool, other leads soldered operation within seconds between Wave soldering SQFP suitable wave soldering, this because likelihood solder bridging closely-spaced leads possibility incomplete solder penetration multi-lead devices.
