HDLx-2416 Series

Four Character 5.0 mm (0.2 inch) Smart 5x7

Alphanumeric Displays

Data Sheet

Description

These are 5.0 mm (0.2 inch) four character 5 x 7 dot matrix

displays driven by an on-board CMOS IC. These displays are

pin for pin compatible with the HPDL-2416. The IC stores

and decodes 7 bit ASCII data and displays it using a 5 x 7

font. Multiplexing circuitry, and drivers are also part of the

IC. The IC has fast setup and hold times which makes it easy

to interface to a microprocessor.

Features

• Enhanced drop-in replacement to HPDL-2416

• Smart alphanumeric display

Built-in RAM, ASCII decoder, and LED drive circuitry

The address and data inputs can be directly connected to the microprocessor address and data buses. The HDLX-2416 has several enhancements over the HPDL2416. 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.

Electrical Description Pin Function Description 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).

Display Clear Cursor Data stored in the Character RAM, Control Register, and Attribute RAM will be cleared if the clear (CLR) is held low for a minimum of 10 µs. 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.

Dimming Figure 3 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. 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.
