Description
The HCMS-29xx ries are high performance, easy to u dot
matrix displays driven by on-board CMOS ICs. Each display can be directly interfaced with a
microprocessor, thus eliminating the need for cumbersome interface components. The rial IC
interface allows higher character 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 upperca, lower ca, Katakana, and custom ur-defined characters. The displays are stackable in the x- and y-directions, making them ideal for high character count displays.

Electrical Description
Pin Function Description
RESET (RST)Sets Control Register bits to logic low. The Dot Register contents are
unaffected by the Ret pin. (logic low = ret; logic high = normal
operation).
DATA IN (D IN)Serial Data input for Dot or Control Register data. Data is entered on the
rising edge of the Clock input.
DATA OUT (D OUT)Serial Data output for Dot or Control Register data. This pin is ud for
cascading multiple displays.
CLOCK (CLK)Clock input for writing Dot or Control Register data. When Chip Enable is
logic low, data is entered on the rising Clock edge.
REGISTER SELECT (RS)Selects Dot Register (RS = logic low) or Control Register (RS = logic high)
as the destination for rial data entry. The logic level of RS is latched on
the falling edge of the Chip Enable input.
CHIP ENABLE (CE)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.
OSCILLATOR SELECT Selects either an internal or external display oscillator source.
(SEL)(logic low = External Display Oscillator; logic high = Internal Display
Oscillator).
OSCILLATOR (OSC)Output for the Internal Display Oscillator (SEL = logic high) or input for an公开课
External Display Oscillator (SEL = logic low).
BLANK (BL)Blanks the display when logic high. May be modulated for brightness
control.
GND LED Ground for LED drivers.
GND LOGIC Ground for logic.
