FUNCTIONAL DESCRIPTION Keyboard operation
SAA3010
Every connection of one X-input and one DR-output will be recognized as a legal key operation and will cause the device to generate the corresponding code. The same applies to every connection of one Z-input to one DR-output with the proviso that SSM must be LOW. When SSM is HIGH a wired connection must exist between a Z-input and a DR-output. If no connection is present the system number will not be generated. Activating two or more X-inputs, Z-inputs or Z-inputs and X-inputs at the same time is an illegal action and inhibits further activity (oscillator will not start). When one X- or Z-input is connected to more than one DR-output, the last scan signal will be considered as legal. The maximum value of the contact series resistance of the switched keyboard is 7 k. Inputs In the quiescent state the command inputs X0 to X7 are held HIGH by an internal pull-up transistor. When the system mode selection (SSM) input is LOW and the system is quiescent, the system inputs Z0 to Z3 are also held HIGH by an internal pull-up transistor. When SSM is HIGH the pull-up transistor for the Z-inputs is switched off, in order to prevent current flow, and a wired connection in the Z-DR matrix provides the system number. Outputs The output signal DATA transmits the generated information in accordance with the format illustrated by Fig.4 and Tables 1 and 2. The code is transmitted using a biphase technique as illustrated by Fig.5. The code consists of four parts: * Start part -1.5 bits (2 x logic 1) * Control part -1 bit * System part -5 bits * Command part -6 bits The output signal MDATA transmits the generated information modulated by 1/12 of the oscillator frequency with a 50% duty factor. In the quiescent state both DATA and MDATA are non-conducting (3-state outputs). The scan driver outputs DR0 to DR7 are open drain n-channel transistors and conduct when the circuit is quiescent. After a legal key operation the scanning cycle is started and the outputs switched to the conductive state one by one. The DR-outputs were switched off at the end of the preceding debounce cycle.

Infrared remote control transmitter RC-5
Combined system mode (SSM is LOW)
SAA3010
The X and Z sense inputs have p-channel pull-up transistors, so that they are HIGH, until pulled LOW by connecting them to an output as the result of a key operation. Legal operation of a key in the X-DR or Z-DR matrix will start the debounce cycle, once key contact has been established for 18 bit-times without interruption, the oscillator enable signal is latched and the key may be released. An interruption within the 18 bit-time period resets the device. At the end of the debounce cycle the DR-outputs are switched off and two scan cycles are started, that switch on the DR-lines one by one. When a Z- or X-input senses a low level, a latch enable signal is fed to the system (Z-input) or command (X-input) latches. After latching a system number the device will generate the last command (i.e. all command bits logic 1) in the chosen system for as long as the key is operated. Latching of a command number causes the chip to generate this command together with the system number memorized in the system latch. Releasing the key will reset the device if no data is to be transmitted at the time. Once transmission has started the code will complete to the end. Single system mode (SSM is HIGH) In the single system mode, the X-inputs will be HIGH as in the combined system mode. The Z-inputs will be disabled by having their pull-up transistors switched off; a wired connection in the Z-DR matrix provides the system code. Only legal key operation in the X-DR matrix will start the debounce cycle, once key contact has been established for 18 bit-times without interruption the oscillator enable signal is latched and the key may be released. An interruption within the 18 bit-time period resets the internal action. At the end of the debounce cycle the pull-up transistors in the X-lines are switched off and those in the Z-lines are switched on for the first scan cycle. The wired connection in the Z-matrix is then translated into a system number and memorized in the system latch. At the end of the first scan cycle the pull-up transistors in the Z-lines are switched off and the inputs are disabled again; the pull-up transistors in the X-lines are switched on. The second scan cycle produces the command number which, after being latched, is transmitted together with the system number. Key release detection An extra control bit is added which will be complemented after key release; this indicates to the decoder that the next code is a new command. This is important in the case where more digits need to be entered (channel numbers of Teletext or Viewdata pages). The control bit will only be complemented after the completion of at least one code transmission. The scan cycles are repeated before every code transmission, so that even with "take over" of key operation during code transmission the right system and command numbers are generated. Reset action The device will be reset immediately a key is released during: * debounce time * between two codes. When a key is released during matrix scanning, a reset will occur if: * a key is released while one of the driver outputs is in the low ohmic stage (logic 0) * a key is released before that key has been detected * there is no wired connection in the Z-DR matrix when SSM is HIGH.

Oscillator
SAA3010
The OSC is the input/output for a 1-pin oscillator. The oscillator is formed by a ceramic resonator, TOKO CRK429, order code, 2422 540 98069 or equivalent. A resistor of 6.8 k must be placed in series with the resonator. The resistor and resonator are grounded at one side. Test Initialization of the circuit is performed when TP1, TP2 and OSC are HIGH. All internal nodes are defined except for the LATCH. The latch is defined when a scan cycle is started by pulling down an X- or Z-input while the oscillator is running. If the debounce cycle has been completed, the scan cycle can be completed 3 x 23 faster, by setting TP1 HIGH. If the scan cycle has been completed, the contents of the latch can be read 3 x 27 faster by setting TP2 HIGH.

SOLDERING Introduction 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). DIP SOLDERING BY DIPPING OR BY WAVE 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. 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. SO 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 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.
