2. High Brightness (HB) LED Controller
Figure 2-1. CY8CLED16P01: HB LED Controller
The HB LED Controller is based on Cypress's EZ-Color™
technology. EZ-Color offers the ideal control solution for high
brightness (HB) LED applications requiring intelligent dimming
control. EZ-Color devices combine the power and flexibility of
PSoC (Programmable System-on-Chip) with Cypress's PrISM™
(Precise Illumination Signal Modulation) modulation technology
providing lighting designers a fully customizable and integrated
lighting solution platform.
The CY8CLED16P01 supports up to 16 independent LED
channels with up to 32 bits of resolution per channel, giving
lighting designers the flexibility to choose the LED array size and
color quality. PSoC Designer software, with lighting-specific user
modules, significantly cuts development time and simplifies
implementation of fixed color points through temperature and
LED binning compensation. EZ-Color's virtually limitless analog
and digital customization enable simple integration of features in
addition to intelligent lighting, such as battery charging, image
stabilization, and motor control during the development process.
These features, along with Cypress's best-in-class quality and
design support, make EZ-Color the ideal choice for intelligent HB
LED control applications.
The list of functions that EZ-Color devices implement are:

2.1 LED Dimming Modulation
The LED Dimming modulators are an important part of any HB
LED application. All EZ-Color controllers are capable of three
primary types of LED dimming modulations. These are:
■
■
■
PWM is among the most commonly used and conventional
methods of modulation. It is straightforward to use and effective
in practice. There are two additional techniques of modulation
supported by EZ-Color that are superior to using the PWM alone:
■
■
LED dimming modulators use digital block resources. Digital
blocks are configurable 8-bit digital peripherals. There are two
types of digital blocks in the CY8CLED16P01: basic and commu-
nication. Usually, there are equal numbers of each. Any commu-
nication functions must be implemented using communication
blocks but basic, noncommunication functions are implemented
using either kind of block.
PWM and DSPWM modulators can have a dimming resolution
of up to 16 bits. A PrISM modulator can theoretically have a
dimming resolution of up to 32 bits, but the maximum recom-
mended resolution for these modulators is 13 bits. This is
because the output signal of a PrISM modulator has a frequency
output range that increases with the resolution of the modulator.
This increase in frequency output range is undesirable as it goes
beyond the switching frequency of the current driver. Therefore,
a resolution of 13 bits or lower is recommended for a PrISM
modulator. Refer to application note AN47372, PrISM
Technology for LED Dimming on http://www.cypress.com, for
details.
To determine the number of digital blocks used by one PWM or
PrISM modulator, use Equation 1. Note that a partial digital block
cannot be used, so the result must always be rounded up. In
Equation 1, n is the dimming resolution of the modulator. The
resolution of dimming is determined by the color accuracy
needed for the end application.
Pulse Width Modulation (PWM)
Precise Illumination Signal Modulation (PrISM)
Delta Sigma Modulated PWM (DSPWM)
PrISM is a modulation technique that is developed and
patented by Cypress. It results in reduced EMI as compared to
the PWM technique while still providing adequate dimming
control for LEDs.
The Delta Sigma Modulated PWM technique provides higher
resolution while using the same hardware resources as a
conventional PWM.
