Description

These are 5 x 7 dot matrix displays with four 0.27" tall characters, driven by an on-board CMOS IC. The IC stores and decodes 7 bit ASCII data and displays it with an easy to read 5 x 7 font. Multiplexing circuitry and drivers are included in the IC to allow the display to interface simply with bus-based micro- processor systems. The address and data inputs of the display can be directly con- nected to the microprocessor address and data buses. These displays are related to the HDLX-2416 family, and thus share the same enhancements over the HPDL-2416 segmented displays. These features include support for the full 128 character ESD Warning: Standard CMOS handling precautions should be observed with the HDLX-3416. US ASCII character set, 8 level dimming control, external hardware dimming capability, and digit blanking. An extended function disable exists for those designers who desire compatibility with competitive displays. This function disables the dimming and digit blanking controls.

Chip Enable (CE1 CE1 and CE2 must be a logic 0 to write to the and CE2, pins display. 3 and 4) Clear When CLR is a logic 0 the ASCII RAM is reset (CLR, pin 5) to 20hex (space) and the Control Register/ Attribute RAM is reset to 00hex. Cursor Enable CUE determines whether the IC displays the (CUE pin 11) ASCII or the Cursor memory. (1 = Cursor, 0 = ASCII.) Cursor Select CU determines whether data is stored in the (CU, pin 10) ASCII RAM or the Attribute RAM/Control Register. (1 = ASCII, 0 = Attribute RAM/ Control Register.) Write WR must be a logic 0 to store data in the (WR, pin 9) display. Address Inputs A0-A1 selects a specific location in the display (A1 and A0, pins memory. Address 00 accesses the far right 7 and 8) display location. Address 11 accesses the far left location. Data Inputs (D0-D6, D0-D6 are used to specify the input data for pins 16 – 22) the display. VDD (pin 6) VDD is the positive power supply input. GND (pin 12) GND is the display ground. Blanking Input BL is used to flash the display, blank the (BL, pin 14) display or to dim the display. Display Internal Block Diagram Figure 1 shows the HDLX-3416 display internal block diagram. The CMOS IC consists of a 4 x 7 Character RAM, a 2 x 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 x 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. 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. 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.
