AVAGO HDSP-253x DATA SHEET

HDSP-253x Series

Eight Character 5 mm Smart Alphanumeric Display

Data Sheet

Description

The HDSP-253x is ideal for applications where displaying
eight or more characters of dot matrix information in an
aesthetically pleasing manner is required. These devices
are eight-digit, 5 x 7 dot matrix, alphanumeric displays.
The 5.0 mm (0.2 inch) high characters are packaged in a

0.300 inch (7.62 mm) 30 pin DIP. The on-board CMOS IC
has the ability to decode 128 ASCII characters, which are
permanently stored in ROM. In addition, 16 programmable
symbols may be stored in on-board RAM. Seven brightness
levels provide versatility in adjusting the display intensity
and power consumption. The HDSP-253x is designed for
standard microprocessor interface techniques. The display
and special features are accessed through a bidirectional
eight-bit data bus.

Notes:

1. Worst case values occur at an IC junction temperature of 125°C.

2. For designers who do not need to read from the display, the Read line can be tied to VDD and the Write and Chip Enable lines can be tied
together.

3. Changing the logic levels of the Address lines when CE = “0” may cause erroneous data to be entered into the Character RAM, regardless of the
logic levels of the WR and RD lines.

4. The display must not be accessed until after 3 clock pulses (110 µs min. using the internal refresh clock) after the rising edge of the reset line.
