ESD WARNING: Standard CMOS handling precautions should be observed with the HDLX-2416.

The address and data inputs can be directly connected to the microprocessor address and data buses. The HDLX-2416 has several enhancements over the HPDL- 2416. These features include an expanded character set, internal 8 level dimming control, external dimming capa- bility, 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. Package Dimensions The difference between the sunlight viewable HDLS- 2416 and the low power HDLU-2416 occurs at power-on or at the default brightness level. Follow ing 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 bright ness levels are identical for both parts. Pin No. Function Pin No. Function

Chip Enable (CE1 and CE1 and CE2 must be a logic 0 to write to the display. CE2, pins 1 and 2) 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 determines whether the IC displays the ASCII or (CUE pin 4) the Cursor memory. (1 = Cursor, 0 = ASCII). Cursor Select CU determines whether data is stored in the ASCII RAM (CU, pin 5) 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 A0-A1 selects a specific location in the display memory. (A1 and A0, Address 00 accesses the far right display location. Pins 8 and 7) Address 11 accesses the far left location. Data Inputs D0-D6 are used to specify the input data for the (D0-D6, Pins 11-17) display. VDD (pin 9) VDD is the positive power supply input. GND (pin 10) GND is the display ground. Blanking Input BL is used to flash the display, blank the (BL, pin 18) display or to dim the display. Display Internal Block Diagram Figure 1 shows the HDLX-2416 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.
