Description
The 3.3 V HCMS-39xx family is similar to the 5.0 V
HCMS-29xx family, except it operates at a lower
operating voltage. Package dimensions and pin outs
are exactly the same for both families. The product has
been thoroughly characterized and stringent reliability
tested to ensure that the product is of high quality.
Similar to the 5.0 V platform, this family product is
a high performance, easy to use dot matrix display
driven by on-board CMOS IC. Each display can be
directly interfaced with a microprocessor, thus
eliminating the need for cumbersome interface com-
ponents. The serial IC interface allows higher character
count information displays with a minimum of data
lines. The easy to read 5x7 pixel format allows the
display of upper case, lower case, Katakana, and custom
user-defined characters. These displays are stackable
in the x- and y-directions, making them ideal for high
character count displays.

Notes:
1. Refers to the initial case temperature of the device immediately prior to measurement.
2. For comparison purpose with existing HCMS-29xx 5 V devices. The Typical and Minimum Luminous Intensity per LED Character Average can be
calculated by dividing the values in the table by two for the test condition 50% Peak Current, 100% Pulse Width and V
LED
= 3.3 V.
3. Measured with all LEDs illuminated in a digit.
4. Dominant wavelength, λ
d
, is derived from the CIE chromaticity diagram and represents the single wavelength which defines the perceived
LED color.
