HCMS-2919, HCMS-2976
High Performance CMOS 5x7 AlphaNumeric GaN Blue Display
Data Sheet
Description
These products are high performance, easy to use dot
matrix displays driven by on-board CMOS IC. Each
display can be directly interfaced with a
microprocessor, thus eliminating the need for
cumbersome interface components. The serial IC
interface allows higher character count information
displays with a minimum of data lines. The 5x7 pixel
format allows the user great freedom to generate user-
defined characters. These displays are stackable in the
x- and y-directions, making them ideal for high
character count displays

)
DATA OUT (D
OUT
)
CLOCK (CLK)
REGISTER SELECT (RS)
Sets Control Register bits to logic low. The Dot Register contents are unaffected by the
Reset pin. (logic low = reset; logic high = normal operation)
Serial Data input for Dot or Control Register data. Data is entered on the rising edge of
the Clock input.
Serial Data out put for Dot or Control Register data. This pin is used for cascading
multiple displays.
Clock input for writing Dot or Control Register data. When Chip Enable is logic low, data
is entered on the rising Clock edge.
Selects Dot Register (RS = logic low) or Control Register (RS = logic high) as the
destination for serial data entry. The logic level of RS is latched on the falling edge of the
Chip Enable input.
This input must be a logic low to write data to the display. When CE returns to logic high
and CLK is logic low, data is latched to either the LED output drivers or a Control Register.
Selects either an internal or external display oscillator source. (SEL) (logic low = External
Display Oscillator; logic high = Internal Display Oscillator).
Output for the Internal Display Oscillator (SEL = logic high) or input for an External
Display Oscillator (SEL = logic low).
Blanks the display when logic high. May be modulated for brightness control.
