This is a 5.0 mm (0.2 inch) four character 5 x 7 dot matrix display
driven by an on-board CMOS IC. This display is 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. The address and data inputs can
be directly connected to the microprocessor address and data buses.
The HDLG-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
HDLG-2416 to operate exactly like an HPDL-2416 by disabling all of the enhancements except the expanded character set.
