HCMS-29xx Series
High Performance CMOS 5 x 7 Alphanumeric Displays
Data Sheet
Description
The HCMS-29xx series are high performance, easy
to use dot matrix displays driven by on-board CMOS ICs.
Each display can be directly interfaced with a microproces-
sor, thus eliminating the need for cumbersome interface
components. The serial IC interface allows higher charac-
ter count information displays with a minimum of data
lines. A variety of colors, font heights, and character
counts gives designers a wide range of product choices
for their specific applications and the easy to read 5 x 7
pixel format allows the display of uppercase, lower case,
Katakana, and custom user-defined characters. These dis-
plays are stackable in the x- and y- directions, making
them ideal for high character count displays.
Features
• Easy to use
• Interfaces directly with microprocessors
• 0.15” character height in 4, 8, and 16 (2x8) character
packages
• 0.20” character height in 4 and 8 character packages
• Rugged X- and Y-stackable package
• Serial input
• Convenient brightness controls
• Wave solderable
• Offered in five colors
• Low power CMOS technology
• TTL compatible
Applications
• Telecommunications equipment
• Portable data entry devices
• Computer peripherals
• Medical equipment
• Test equipment
• Business machines
• Avionics
• Industrial controls
