Some key features of ZIP LEDs are:
- Each ZIP LED has a Red, Green and Blue element within the LED, and each of these can achieve 256 levels of brightness. This results in 16,777,216 possible output colours.
- Integrated intelligent reverse connect protection, so a reverse connection of the power supply does not damage the IC in each of the LEDs.
- Simple 3 wire connection for all LEDs.
- LEDS can be placed up to 5m apart without the need for any additional circuitry.
How do ‘ZIP’ LEDs work?The ZIP LEDs are connected using a three wire bus. These connects are V+ (3.5V to 5.3V), Gnd (Vss) and Data. The data is fed into the data in pin on the first LED and then out of the data out pin. This then feeds on to the next LED as shown in the graphic below which is taken from the datasheet. The data structure is as follows: Each 0 or 1 is sent as 1.25uS high to low cycle. The length of the high and low determines if it is a 0 or a 1 being sent. The times are as follows:
|T0H||0 code, high time||0.4us|
|T0L||0 code, low time||0.85us|
|T1H||1 code, high time||0.85us|
|T1L||1 code, low time||0.4us|
|RET||1 code, low time||>50us|
