The HDLX-2416 has several enhancements over the HPDL-2416. These features include an expanded character set, internal 8-level dimming control, external dimming capability, and individual digit blanking. Finally, the extended functions can be disabled which allows the HDLX-2416 to operate exactly like an HPDL-2416 by disabling all of the enhancements except the expanded character set. The difference between the sunlight viewable HDLS-2416 and the low power HDLU-2416 occurs at power-on or at the default brightness level. Following power up, the HDLS-2416 operates at the 100% brightness level, while the HDLU-2416 operates at the 27% brightness level. Power on sets the internal brightness control (bits 3–5) in the control register to binary code (000). For the HDLS-2416 binary code (000) corresponds to a 100% brightness level, and for the HDLU-2416 binary code (000) corresponds to a 27% brightness level. The other seven brightness levels are identical for both parts. Broadcom -2- HDLx-2416 Series Data Sheet Package Dimensions 25.15 (0.990) 3.05 (0.120) 0.38 REF. (0.015) 0.25 ± 0.13 TYP.

Electrical Description Pin Function Description Chip Enable (CE1 and CE2, pins 1 and 2) CE1 and CE2 must be a logic 0 to write to the display. Clear (CLR, pin 3) When CLR is a logic 0 the ASCII RAM is reset to 20hex (space) and the Control Register/Attribute RAM is reset to 00hex. Cursor Enable (CUE pin 4) CUE determines whether the IC displays the ASCII or the Cursor memory. (1 = Cursor, 0 = ASCII). Cursor Select (CU, pin 5) CU determines whether data is stored in the ASCII RAM or the Attribute RAM/Control Register. (1 = ASCII, 0 = Attribute RAM/Control Register). Write (WR, pin 6) WR must be a logic 0 to store data in the display. Address Inputs (A1 and A0, Pins 8 and 7) A0–A1 selects a specific location in the display memory. Address 00 accesses the far right display location. Address 11 accesses the far left location. Data Inputs (D0–D6, Pins 11-17) D0–D6 are used to specify the input data for the display. VDD (pin 9) VDD is the positive power supply input. GND (pin 10) GND is the display ground. Blanking Input (BL, pin 18) BL is used to flash the display, blank the display or to dim the display. Broadcom - 10 - HDLx-2416 Series Data Sheet Display Internal Block Diagram Figure 1 shows the HDLX-2416 display internal block diagram. The CMOS IC consists of a 4×7 Character RAM, a 2×4 Attribute RAM, a 5-bit Control Register, a 128 character ASCII decoder and the refresh circuitry necessary to synchronize the decoding and driving of four 5×7 dot matrix displays. Four 7-bit ASCII words are stored in the Character RAM. The IC reads the ASCII data and decodes it via the 128 character ASCII decoder. The ASCII decoder includes the 64 character set of the HPDL-2416, 32 lower case ASCII symbols, and 32 foreign language symbols. For each display digit location, two bits are stored in the Attribute RAM. One bit is used to enable a cursor character at each digit location. A second bit is used to individually disable the blanking features at each digit location. The display is blanked and dimmed through an internal blanking input on the row drivers. Logic within the IC allows the user to dim the display either through the BL input or through the brightness control in the control register. Similarly the display can be blanked through the BL input, the Master Blank in the Control Register, or the Digit Blank Disable in the Attribute RAM. A 5-bit word is stored in the Control Register. Three fields within the Control Register provide an 8-level brightness control, master blank, and extended functions disable.

Note that the display will be cleared regardless of the state of the chip enables (CE1, CE2). After the display is cleared, the ASCII code for a space (20hex) is loaded into all character RAM locations and 00hex is loaded into all Attribute RAM/Control Register memory locations. When cursor enable (CUE) is a logic 1, a cursor will be displayed in all digit locations where a logic 1 has been stored in the Digit Cursor memory in the Attribute RAM. The cursor consists of all 35 dots ON at half brightness. A flashing cursor can be displayed by pulsing CUE. When CUE is a logic 0, the ASCII data stored in the Character RAM will be displayed regardless of the Digit Cursor bits. Data Entry Blanking Figure 2 shows a truth table for the HDLX-2416 display. Setting the chip enables (CE1, CE2) to logic 0 and the cursor select (CU) to logic 1 will enable ASCII data loading. When cursor select (CU) is set to logic 0, data will be loaded into the Control Register and Attribute RAM. Address inputs A0–A1 are used to select the digit location in the display. Data inputs D0–D6 are used to load information into the display. Data will be latched into the display on the rising edge of the WR signal. D0–D6, A0– A1, CE1, CE2, and CU must be held stable during the write cycle to ensure that correct data is stored into the display. Data can be loaded into the display in any order. Note that when A0 and A1 are logic 0, data is stored in the right most display location. Blanking of the display is controlled through the BL input, the Control Register and Attribute RAM. The user can achieve a variety of functions by using these controls in different combinations, such as full hardware display blank, software blank, blanking of individual characters, and synchronized flashing of individual characters or entire display (by strobing the blank input). All of these blanking modes affect only the output drivers, maintaining the contents and write capability of the internal RAMs and Control Register, so that normal loading of RAMs and Control Register can take place even with the display blanked. Broadcom - 13 - HDLx-2416 Series Data Sheet Figure 2 Display Truth Table Broadcom - 14 - HDLx-2416 Series Data Sheet Table 1 shows how the Extended Function Disable (bit D6 of the Control Register), Master Blank (bit D2 of the Control Register), Digit Blank Disable (bit D1 of the Attribute RAM), and BL input can be used to blank the display. When the Extended Function Disable is a logic 1, the display can be blanked only with the BL input. When the Extended Function Disable is a logic 0, the display can be blanked through the BL input, the Master Blank, and the Digit Blank Disable. The entire display will be blanked if either the BL input is logic 0 or the Master Blank is logic 1, providing all Digit Blank Disable bits are logic 0. Those digits with Digit Blank Disable bits a logic 1 will ignore both blank signals and remain ON. The Digit Blank Disable bits allow individual characters to be blanked or flashed in synchronization with the BL input. Table 1 Display Blanking Truth Table EFD MB DBDn BL 0 0 0 0 0 0X 1 Display ON 0 X 1 0 Display blanked by PL. Individual characters "ON" based on "1" being stored in DBDn Dimming Dimming of the display is controlled through either the BL input or the Control Register. A pulse width modulated signal can be applied to the BL input to dim the display. A three bit word in the Control Register generates an internal pulse width modulated signal to dim the display. The internal dimming feature is enabled only if the Extended Function Disable is a logic 0. Bits 3–5 in the Control Register provide internal brightness control. These bits are interpreted as a three bit binary code, with code (000) corresponding to the maximum brightness and code (111) to the minimum brightness. In addition to varying the display brightness, bits 3–5 also vary the average value of IDD. IDD can be specified at any brightness level as shown in Table 2.

This package construction makes the display highly tolerant to temperature cycling and allows wave soldering. Figure 3 Intensity Modulation Control using an Astable Multivibrator (reprinted with permission from Electronics magazine, Sept.19, 1974, VNU Business pub. Inc.) The inputs to the CMOS IC are protected against static discharge and input current latchup. However, for best results standard CMOS handling precautions should be used. Prior to use, the HDLX-2416 should be stored in anti-static tubes or conductive material. During assembly a grounded conductive work area should be used, and assembly personnel should wear conductive wrist straps. Lab coats made of synthetic material should be avoided since they are prone to static charge build-up. + VDD 1k 4 8 3 7 1k 1N914 BL (PIN 18) 10 kHz OUTPUT 555 Input current latchup is caused when the CMOS inputs are subjected either to a voltage below ground (Vin < ground) or to a voltage higher than VDD (Vin > VDD) and when a high current is forced into the input. To prevent input current latchup and ESD damage, unused inputs should be connected either to ground or to VDD. Voltages should not be applied to the inputs until VDD has been applied to the display. Transient input voltages should be eliminated. 6 250 k LOG 2 1 400 pF Figure 3 shows a circuit designed to dim the display from 98% to 2% by pulse width modulating the BL input. A logarithmic or a linear potentiometer may be used to adjust the display intensity. However, a logarithmic potentiometer matches the response of the human eye and therefore provides better resolution at low intensities. The circuit frequency should be designed to operate at 10 kHz or higher. Lower frequencies may cause the display to flicker. Extended Function Disable Extended Function Disable (bit D6 of the Control Register) disables the extended blanking and dimming functions in the HDLX-2416. If the Extended Function Disable is a logic 1, the internal brightness control, Master Blank, and Digit Blank Disable bits are ignored. However the BL input and Cursor control are still active. This allows downward compatibility to the HPDL-2416. Mechanical and Electrical Considerations The HDLX-2416 is an 18 pin DIP package that can be stacked horizontally and vertically to create arrays of any size. The HDLX-2416 is designed to operate continuously from –40°C to +85°C for all possible input conditions. The HDLX-2416 is assembled by die attaching and wire bonding 140 LEDs and a CMOS IC to a high temperature printed circuit board. A polycarbonate lens is placed over the PC board creating an air gap environment for the LED wire bonds. Backfill epoxy environmentally seals the display Soldering and Post Solder Cleaning Instructions for the HDLX-2416 The HDLX-2416 may be hand soldered or wave soldered with SN63 solder. When hand soldering it is recommended that an electronically temperature controlled and securely grounded soldering iron be used. For best results, the iron tip temperature should be set at 315°C (600°F). For wave soldering, a rosin-based RMA flux can be used. The solder wave temperature should be set at 245°C ±5°C (473°F ±9°F), and dwell in the wave should be set between 1.5 to 3 seconds for optimum soldering. The preheat temperature should not exceed 110°C (230°F) as measured on the solder side of the PC board. For further information on soldering and post solder cleaning, see Application Note 1027, Soldering LED Components. Contrast Enhancement The objective of contrast enhancement is to provide good readability in the end user’s ambient lighting conditions. The concept is to employ both luminance and chrominance contrast techniques. These enhance readability by having the OFF-dots blend into the display background and the ON-dots vividly stand out against the same background. For additional information on contrast enhancement, see Application Note 1015.
