Typ. Typ. Typ. AlGaAs Red HCMS- 29X5 95 230 645 637 High Efficiency Red HCMS- 29X2 29 64 635 626 Orange HCMS- 29X4 29 64 600 602 Yellow HCMS- 29X1 29 64 583 585 Green HCMS- 29X3 57 114 568 574 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 Description RESET (RST) Sets Control Register bits to logic low. The Dot Register contents are unaffected by the Reset pin. (logic low = reset; 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 used 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 serial 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 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. V LED Positive supply for LED drivers. V LOGIC Positive supply for logic. |
