Data Sheet HDLX-1414 Series Four-Character Smart Alphanumeric Displays Description Features These Broadcom 3.7-mm (0.145-in.) four-character 5 7 Dot matrix replacement of HPDL-1414 dot matrix displays are driven by an on-board CMOS IC. Smart alphanumeric display These displays are pin for pin compatible with the Built-in RAM, ASCII decoder, and LED drive circuitry HPDL-1414.The IC stores and decodes 7-bit ASCII data 128 ASCII character set and displays it in an easy to read 5 7 font. Multiplexing and End stackable LED drive circuitry are also included in the display, and fast Categorized for luminous intensity Yellow and Green setup and hold times allow it to interface easily with common categorized for color microprocessors. Low-power and sunlight-viewable AlInGaP Deep Red versions The address and data inputs can be directly connected to Wide viewing angle (50 typical) microprocessor address and data buses. The HDLX-1414 offers a larger character set than the HPDL-1414. Lowercase letters and special symbols are now offered, made possible by the 5 7 dot matrix character layout. The difference between the sunlight-viewable HDLS-1414 and the low-power HDLU-1414 lies in the brightness level. The sunlight-viewable version is internally set to provide high-intensity characters. The low-power version uses the same bright LED technology, but reduces the current through each LED to a much lower level, and maintains an intensity comparable to the HDLO-1414.
