Current drive to the LEDs is selected with an external resistor. The required resistor value can be indicated on the part. Serial data transfer from the data source to the dis- play driver is accomplished with three signals: data input, data enable, and clock. The data format consists of a lead- ing 1 followed by 35 data bits. The 35 data bits are latched after the 36th bit is complete, thus providing non- multiplexed direct drive to the display. Outputs change only if the serial data bits differ from the previous time. THREE-FIVE SYSTEMS, INC. THREE-FIVE SYSTEMS, LTD.

The start bit precedes the 35 data bits. At the 36th clock, a LOAD signal is generated synchronously with the high state of the clock, which loads the 35 bits in the shift registers into the latches. At the low state of the clock, a RESET signal is generated which clears all the shift registers for the next set of data. The shift registers are static master-slave configurations. There is no clear for the master portion of the first shift register, thus allowing continuous operation. If the clock is not continuous, there must be a com- plete set of 36 clocks, otherwise the shift registers will not clear. When the chips first powers ON, an internal power ON reset signal is generated which resets all registers and all latches. The START bit and the first clock return the chip to its normal operation. To clear the display, load a 1 followed by 35 Os. This blanks the LED and resets the driver IC. Bit 1 is the first bit following the start bit and determines the drive current state of the decimal point of digit 4 (note: segment and digit designations are given inthe block dia- gram of Figure 1). The bit sequence for all segments is shown in Table 1. The LED element current is typically 25 times greater than the current into the brightness control pin as shown in Figure 4. Relationship of the LED current to LED supply voltage is shown in Figure 2. A .0ipF capacitor must be connected from the bright- ness control pin to the ground pin to prevent oscilla- tions.

This is done by connecting an appro- priate resistor between the brightness input and the VDD (5.0V) pin. This resistor is located on the customer's TABLE 2Part Marking mother board. Three-Five Systems, Inc. can test each part and mark it with the appropriate resistor value to be used, In addition, a Customer Bin Code is marked on the part. The relationship between Resistor Value and Customer Bin Code is given in Table 2.

The edge connector tab will withstand 230C for 5 seconds. Permanent damage to the display will result if reflector temperature exceeds 70C. Since the display is not hermetic, immersion of the entire package during flux and clean operation may cause condensation of flux or cleaner on the underside of the reflector.

Freon TF, lsopropanol, Methanol or Ethanol solvents are recommended only at room temperature and for short periods. The use of other solvents or elevated temperature use of the recom- mended solvents may cause permanent damage to the reflector or display. The TSM6X55 Series are CMOS devices and normal precautions should be taken to avoid static damage. @ Copyright 9/89 a THREE-FIVE SYSTEMS, INC. = Phoenix, Arizona TEL: 602-496-0035; FAX: 602-496-0168 THREE-FIVE SYSTEMS, LTD.
