■ Cascading data structure

32 consecutive 0’s denote the start of a command for an RGB LED. After receiving 32 0’s, IC gets the following 32 bits as the received command, including FLAG, DIMMING, BLUE, GREEN and RED fields.

The serial command is transmitted with MSB first, DIN is latched at the rising edge of CIN clock. COUT and DOUT are re-generated for the next RGB LED. COUT is inverted from CIN. When 32 consecutive 0’s are encountered, the next 1 is expected to start a 32-bit command, i.e., FLAG [2:0]=111. When FLAG [2:0]=111, then DIMMING, BLUE, GREEN and RED fields are latched respectively. While the current 32-bit command is got, IC passes remaining command bits to the next RGB LED.

After the last one command is issued for the last LED (LED n), the following 32 consecutive 1’s denote the end of the current command for an RGB LED(End of Frame) and wait for next 32 consecutive 0’s to start a new command set.(Note: IC is workable either with or without “End of Frame” command, but MCU should issue the extra N/2 numbers of clocks signal if there are N LED lamps totally connected in the strip to make sure the data transfer and display of the last one LED lamp is complete and correct)

FLAG [2:0] : 111 to start a 32-bit command DIMMING [4:0] : 32-level current control for R/G/B drivers BLUE [7:0] : 256 gray levels for blue LED GREEN [7:0] : 256 gray levels for green LED RED [7:0] : 256 gray levels for red LED

Sleep and power saving mode

IC supports the sleep/wake-up modes for power-saving purpose. In sleep mode, the built-in oscillator and associated circuitry will be disabled. The quiescent current of IC is approximately 1uA (typ.).

Command Setup to enable sleep or wake up mode

When receiving 24-bit 0’s BGR data (that is BLUE [7:0]=8h00, G [7:0]=8h00, R [7:0]=8h00), in the meantime, both of the data in 3-bits’ flag and 5-bits’ DIMMING is 8h’A0’ (that is FLAG [2:0]=3b101 and DIMMING [4:0]=5b00000), IC will enter sleep mode.

IC will wake up from sleep mode once receiving the new data with the data of Flag [2:0], DIMMING [4:0] is not 8h"A0"; after wake-up, all sleeping circuits in IC return to normal working mode within 1ms. Since it takes 1ms for a sleeping IC returning to normal function mode, it is recommended for a host to wait for 1ms to send display data and command after issuing a wake-up command.

Sleep power-saving mode example:

Page 11

In case 2, while lamp2 is under sleep mode, in the following data transfer process, the state of lamp 2 will be not changed as long as the 32 bits data for lamp 2 is received with data of Flag [2:0]、DIMMING [4:0] being 8h”A0” . It means lamp2 will keep in sleep mode as well. In the situation, lamp2 can pass through the remaining data to lamp 3 (32bits) to change the display data of lamp 3. In other words, the sleeping chip is able to pass the data to the next chips.

Precaution for Use 1. The chips should not be used directly in any type of fluid such as water, oil, organic solvent, etc. 2. When the LEDs are illuminating, the maximum ambient temperature should be first considered before operation. 3. LEDs must be stored in a clean environment. A sealed container with a nitrogen atmosphere is necessary if the storage period is over 3 months after shipping. 4. The LEDs must be used within 24 hrs after unpacked. Unused products must be repacked in an anti-electrostatic package, folded to close any opening and then stored in a dry and cool space. 5. The appearance and specifications of the products may be modified for improvement

without further notice. 6. The LEDs are sensitive to the static electricity and surge. It is strongly recommended to use a grounded wrist band and anti-electrostatic glove when handling the LEDs.If a voltage over the absolute maximum rating is applied to LEDs, it will damage LEDs.Damaged LEDs will show some abnormal characteristics such as remarkable increase of leak current, lower turn-on voltage and getting unlit at low current.

Packing

5 or 10 boxes per carton is available depending on shipment quantity.

Page 15

Dry Pack All SMD optical devices are MOISTURE SENSITIVE. Avoid exposure to moisture at all times during transportation or storage. Every reel is packaged in a moisture protected anti-static bag. Each bag is properly sealed prior to shipment.

Upon request, a humidity indicator will be included in the moisture protected anti-static bag prior to shipment.

The packaging sequence is as follows:

Baking Baking before soldering is recommended when the package has been unsealed for 72 hrs. The conditions are as followings: 1. 60±3℃×(12~24hrs)and<5%RH, taped reel type. 2. 100±3℃×(45min~1hr), bulk type. 3. 130±3℃×(15min~30min), bulk type. Precautions 1. Avoid exposure to moisture at all times during transportation or storage. 2. Anti-Static precaution must be taken when handling GaN, InGaN, and AlInGaP products. 3. It is suggested to connect the unit with a current limiting resistor of the proper size. Avoid applying a reverse voltage beyond the specified limit. 4. Avoid operation beyond the limits as specified by the absolute maximum ratings. 5. Avoid direct contact with the surface through which the LED emits light.

1. If possible, assemble the unit in a clean room or dust-free environment.

Handling of Silicone Resin LEDs Handling Indications During processing, mechanical stress on the surface should be minimized as much as possible. Sharp objects of all types should not be used to pierce the sealing compound.

Figure 1

In general, LEDs should only be handled from the side. By the way ,this also applies to LEDs without a silicone sealant, since the surface can also become scratched.

Figure 2 When populating boards in SMT production, there are basically no restrictions regarding the from of the pick and place nozzle, except that mechanical pressure on the surface of the resin must be prevented. This is assured by choosing a pick and place nozzle which is large than LEDs reflector area.

Reflow Soldering Recommend soldering paste specifications: 1. Operating temp.: Above 217 OC ,60~150 sec. 2. Peak temp.:260 OCMax.,10sec Max. 3. Reflow soldering should not be done more than two times. 4. Never attempt next process until the component is cooled down to room temperature after reflow. 5. The recommended reflow soldering profile (measured on the surface of the LED terminal) is as following: Lead-free Solder Profile

Reworking  Rework should be completed within 5 seconds under 260 OC.  The iron tip must not come in contact with the copper foil.  Twin-head type is preferred.

Cleaning Following are cleaning procedures after soldering:  An alcohol-based solvent such as isopropyl alcohol (IPA) is recommended.  Temperature x Time should be 50oC x 30sec. or <30oC x 3min  Ultrasonic cleaning: < 15W/ bath; bath volume ≤ 1liter  Curing: 100 OC max, <3min Cautions of Pick and Place  Avoid stress on the resin at elevated temperature.

 Avoid rubbing or scraping the resin by any object.  Electric-static may cause damage to the component. Please ensure that the equipment is properly grounded. Use of an ionizer fan is recommended.  Revise History
