Overview

The HDSP-210x/-211x/-250x series of products is ideal for

applications where displaying eight or more characters of

dot matrix information in an aesthetically pleasing manner is

required. These devices are 8-digit, 5×7 dot matrix,

alphanumeric displays and are all packaged in a standard

15.24 mm (0.6 inch) 28-pin DIP.

The onboard 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

onboard ROM, allowing considerable flexibility for

displaying additional symbols and icons. Seven brightness

levels provide versatility in adjusting the display intensity

and power consumption.

HDSP-210x/211x/-250x products are designed for standard

microprocessor interface techniques. The display and

special features are accessed through a bidirectional 8-bit

data bus.

During a normal access, the CE = 0 and either RD = 0 or WR = 0. However, erroneous data may be written into the Character RAM if the address lines are unstable when CE = 0 regardless of the logic levels of the RD or WR lines. Address lines A0–A2 are used to select the location in the Character RAM.

The UDC Address Register is eight bits wide. The lower four bits (D0–D3) are used to select one of the 16 UDC locations. The upper four bits (D4–D7) are not used. Once the UDC address has been stored in the UDC Address Register, the UDC RAM can be accessed.

HDSP-210x/-211x/-250x Series Data Sheet Eight-Character 5 mm and 7 mm Smart Alphanumeric Displays Blink Function (Bit 4) Bit 4 of the Control Word is used to synchronize blinking of all eight digits of the display. When this bit is a 1, all eight digits of the display blinks at approximately 2 Hz. The actual rate is dependent on the clock frequency. For an external clock, the blink rate can be calculated by dividing the clock frequency by 28,672.

Results of the internal self test are stored in bit 5 of the Control Word. Bit 5 is a read only bit where bit 5 = 1 indicates a passed self test and bit 5 = 0 indicates a failed self test. Setting bit 6 to a logic 1 starts the self-test function.
