Can be used to connect to Din of the next SMARTSWITCH. As a result, many SMARTSWITCHES can be controlled with one clock and data signal. 6 FLM First Line Marker The marking signal for the first line data of LCD display. The first line of LCD will be selected by the falling edge of LP signal during the high level (FLM). 7 LP Latch Pulse Line data latch pulse will latch content of internal 40-bit shift register at falling edge for one line of display. LP will also increment the display line by one. 8 SCP Serial Clock Pulse Clock used by 40-bit internal shift register of the switch, shifting the display data bit presented at Din at falling edge. 9 Din Data Input Display serial data bit. Note: to map the display data, because of the difference between the number of internal shift register data (40) and the single line of LCD pixels (36), the first four bits of data shifted will be dummy bits. 10 GND 11 VDD Power Power source for logic circuit 12 VLC Power Power source for LCD drive 13 BL-LED (+) Terminal of Backlight LED Anode for common 14 BL-LED (–) Terminal of Backlight LED Cathode for green Ground NKK Switches • email: [email protected] • Phone (480) 991-0942 • Fax (480) 998-1435 • www.nkksmartswitch.com 3 SMARTSWITCH TM SUPER BRIGHT LED SPECIFICATIONS Typical Electrical Characteristics (Temperature at 25°C) Backlight Color Symbols Red Green Blue Unit Forward Current IF 10 10 10 mA Forward Voltage VF 2.1 3.3 3.3 V ABSOLUTE MAXIMUM FOR LEDS Electrical Characteristics (Temperature at 25°C) Backlight Color Symbols Red/Green/Blue Unit Forward Current IF 20 mA Reverse Voltage VR 4.0 V –0.27 mA/°C 135 maximum mW Current Reduction Rate Above 25°C ∆ I F (D C) Power Dissipation* PD *For uniform light emission, Power Dissipation should not exceed the Absolute Maximum Rating.

The VLC voltage should not be applied before logic voltage. If VLC voltage is present before logic voltage, it may cause the driver logic to freeze and damage the LCD, and the driver logic itself may become damaged. ATTENTION The IS Series devices are electrostatic sensitive. ELECTROSTATIC SENSITIVE DEVICES Limit operating force to keytop to 100.0N maximum, as excessive pressure may damage LCD device. Recommended soldering time and temperature limits are 5 seconds maximum @ 270°C maximum. Do not exceed 60°C at the LCD level. The IS series devices are not process sealed. If the LCD is accidentally broken, avoid contact with the liquid and wash off any liquid spills to the skin or clothing. Clean cap surface with dry cloth. If further cleaning is needed, wipe with dampened cloth using neutral cleanser and dry with clean cloth. Do not use organic solvent. Storage 1. Store away from direct sunlight. 2. Keep away from static electricity. 3. Avoid extreme temperatures, high humidity, gaseous substances, and all forms of chemical contamination.
