Hp - hdls-2416 - red 4 digit alphanumeric smart display


This is a 5.0 mm (0.2 inch) four character 5 x 7 dot matrix display driven by an on-board CMOS IC. The 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 HDLS-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 HDLS-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. Power on sets the internal brightness control (bits 3-5) in the control register to binary code (000). The HDLS-2416 binary code (000) corresponds to a 100% brightness level.
