Notes:

1. Refers to the initial case temperature of the device immediately prior to measurement.

2. Measured with all LEDs illuminated.

3. Dominant wavelength,

λ

d

, is derived from the CIE chromaticity diagram and represents the single wavelength which defines the

perceived LED color.

Electrical Description

Pin Function

RESET (RST)

Description

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 output 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.

(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.

Ground for LED drivers.

Ground for logic.

Positive supply for LED drivers.
