HCMS-235x Data Sheet CMOS Extended Temperature Range 5 × 7 Alphanumeric Display Broadcom AV02-0195EN Electrical Description The display contains four 5 x 7 LED dot matrix characters and two CMOS integrated circuits, as shown in Figure 1. The two CMOS integrated circuits form an on-board 28-bit serial-in/parallel-out shift register that accepts standard TTL logic levels. The Data Input, pin 12, is connected to bit position 1 and the Data Output, pin 7, is connected to bit position 28. The shift register puts out control constant current sinking LED row drivers. A logic 1 stored in the shift register enables the corresponding LED row driver and a logic 0 stored in the shift register disables the corresponding LED row driver. The electrical configuration of these CMOS IC alphanumeric displays allows for an effective interface to a display controller circuit, which supplies decoded character information. The row data for a given column (one 7-bit byte per character) is loaded (bit serial) into the on-board 28-bit shift register with high-to-low transitions of the clock input. To load decoded character information into the display, column data for character 4 is loaded first, and the column data for character 1 is loaded last in the following manner. The 7 data bits for column 1, character 4, are loaded into the on-board shift register. Next, the 7 data bits for column 1, character 3, are loaded into the shift register, shifting the character 4 data over one character position. This process is repeated for the other two characters until all 28 bits of column data (four 7-bit bytes of character column data) are loaded into the on-board shift register. Then the column 1 input, V COL pin 1, is energized to illuminate column 1 in all four characters. This process is repeated for columns 2, 3, 4, and 5. All V COL inputs should be at logic low to ensure that the display is off when loading data. The display is blank when the blanking input VB, pin 8, is at logic low regardless of the outputs of the shift register or whether one of the VCOL inputs is energized.

HCMS-235x Data Sheet CMOS Extended Temperature Range 5 × 7 Alphanumeric Display Broadcom AV02-0195EN ESD Susceptibility The display has an ESD susceptibility rating of Class 3 of MIL-STD-883E, HBM. Take normal CMOS handling precautions when handling these devices. Soldering and Post Solder Cleaning These displays may be soldered with a standard wave solder process using either an RMA flux and solvent cleaning or an OA flux and aqueous cleaning. For optimum soldering, the solder wave temperature should be 245°C, and the dwell time for any display lead passing through the wave should be 1.5 to 2 seconds. For more detailed information, refer to Application Note 1027, Soldering LED Components. Contrast Enhancement When used with the proper contrast enhancement filters, the display is readable in sunlight. Refer to Application Note 1029, Luminous Contrast and Sunlight Readability of the HDSP-235X Series Alphanumeric Displays for Sunlight Viewable Applications, for information on contrast enhancement for sunlight and daylight ambient. Refer to Application Note 1015, Contrast Enhancement Techniques for LED Displays, for information on contrast enhancement in moderate ambients. Night Vision Lighting When used with the proper NVG/DV filters, the HCMS-235x display may be used in night vision lighting applications. For a list of NVG/DV filters and a description on night vision lighting technology, refer to Application Note 1030, LED Displays and Indicators and Night Vision Imaging System Lighting. Controller Circuits, Power Calculations, and Display Dimming Refer to Application Note 1016, Using the HDSP-2000 Alphanumeric Display Family, for information on controller circuits to drive these displays, how to do power calculations, and a technique for display dimming.
